Technical Field

The present invention relates to a reaction vessel for a diagnostic analyzer using re-usable and/or disposable parts used in contact with samples.

Background art

In vitro diagnostic testing has a major effect on clinical decisions, providing physicians with pivotal information. Particularly, there is great emphasis on providing quick and accu rate test results in critical care settings. In vitro diagnostic testing is usually performed by diagnostic analyzers using instruments operable to execute one or more processing steps or workflow steps on one or more biological samples and/or one or more reagents, such as pre-analytical instruments, post-analytical instruments and also analytical instruments.

Diagnostic instruments or analyzers are configured to obtain a measurement value from a sample. A diagnostic analyzer is operable to determine via various chemical, biological, physical, optical or other technical procedures a parameter value of the sample or a com ponent thereof. A diagnostic analyzer may be operable to measure said parameter of the sample or of at least one analyte and return the obtained measurement value. The list of possible analysis results returned by the analyzer comprises, without limitation, concentra tions of the analyte in the sample, a digital (yes or no) result indicating the existence of the analyte in the sample (corresponding to a concentration above the detection level), optical parameters, DNA or RNA sequences, data obtained from mass spectrometry of proteins or metabolites and physical or chemical parameters of various types. A diagnostic analyzer may comprise units assisting with the pipetting, dosing, and mixing of samples and/or rea gents.

The diagnostic analyzer may comprise a process and detection system whose workflow is optimized for certain types of analysis. Examples of such analyzers are clinical chemistry analyzers, coagulation chemistry analyzers, immunochemistry analyzers, urine analyzers, nucleic acid analyzers, used to detect the result of chemical or biological reactions or to monitor the progress of chemical or biological reactions.

Such automatic diagnostic analyzers allow to increase the number of analytical processes and obtainable measurements values. For this reason, such automatic diagnostic analyzers use several processing stations for processing several samples provided in reaction vessels at the same time. For example, 2 to 8 or even more different processing stations are present with such a diagnostic analyzer for preparing, processing, analyzing the respective sam ples.

Many processes during automated sample handling and sample preparation cannot be ob served on a running, closed system. Sometimes, the software does not allow special func tions to conduct only parts of an automated sample workflow. In other cases, the complex system architecture does not allow to observe the specific positions in the analytical unit. That makes specification testing, optimization and troubleshooting very cumbersome. Cur rently no tools are available to investigate the sample preparation processes from a sample point of view on such diagnostic analyzers. The influence on the patient sample can only be investigated indirect via (continuous) system monitoring or quality control sample out comes. Further, currently large manual efforts with respect to mechanical adjustment of the components of processing stations and/or moving mechanical parts in diagnostic analyzers are necessary. Often, two field service engineers are necessary, one at a computer to con trol components and another to guide the mechanical part due to distance between the part and the computer interface.

According to a first aspect of the present disclosure, a reaction vessel for a diagnostic ana lyzer comprising a plurality of processing stations is disclosed, wherein the reaction vessel comprises: at least one sensor configured to measure at least one physical parameter associated with at least one of the processing stations of the diagnostic analyzer, a memory configured to at least temporarily store at least one measurement value indicat ing the physical parameter measured by the sensor, a processing unit configured to control the sensor and to output measurement data includ ing the measurement value from the memory, an interface configured to provide communication of the processing unit with an external electronic device, a power source configured to supply electric power to the sensor, the processing unit and the memory, wherein the reaction vessel defines an internal volume, wherein the sensor, the processing unit, the memory and the interface are arranged within the internal volume.

Thus, an intelligent or smart reaction vessel equipped with one or more miniaturized sen sors is suggested, which can be processed like a real patient sample vessel for checking the functionality of the respective processing stations of the diagnostic analyzer. Particularly, the provision of one or more sensors allows to measure at least one physical parameter associated with at least one of the processing stations of the diagnostic analyzer. With oth er words, the reaction vessel is handled like a “normal” sample vessel and detects the phys ical parameter at or in the respective processing station by means of the one or more sen sors. The memory allows to at least temporarily store the measurement results as provided by the one or more sensors. The processing unit controls operation of the one or more sen sors and outputs the measurement results as appropriate, e.g. after receiving a correspond ing output request or command. The interface allows to processing unit to communication with an electronic device external to the reaction vessel. The power source supplies electric power to the electronic components of the reaction vessel such as the one or more sensors, the processing unit and the memory. Furthermore, all electronic components such as the one or more sensors, the processing unit and the memory are miniaturized so as to fit with in the internal volume defined by the reaction vessel.

Further, the reaction vessel provides lower cost of ownership by workflow improvements and thus higher instrument uptime. Still further, the reaction ves sel provides cost reduction for the manufacturer by faster troubleshooting or lower fre quency of service engineer visits at a customer. Still further, the reaction vessel provides a shorter time for service engineer visits by automation through faster root cause analysis. Further, different parties profit by resolving instrument malfunction faster and narrowing down error sources. Furthermore, the reaction vessel provides an option on remote service with further time saving potential.

The term “reaction vessel” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a container defining a rather small volume configured to receive a small volume of a sample which is intended to be subject to a chemical and/or physical reaction by a diagnostic ana lyzer. The reaction takes place within the vessel. The term “diagnostic analyzer” as used herein is a broad term and is to be given its ordi nary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to any apparatus or apparatus component operable to execute one or more processing steps/workflow steps on one or more biological samples. The term “processing step” thereby refers to physically executed processing steps such as centrifugation, aliquotation, sample analysis and the like. The term “analyzer” covers pre-analytical sample work-cells, post-analytical sample work-cells and also analytical work-cells. Non-limiting examples for diagnostic analyzers are clinical chemistry analyzers, coagulation chemistry analyzers, immunochemistry analyzers, urine analyzers, nucleic acid analyzers, used to detect the result of chemical or biological reactions or to monitor the progress of chemical or biologi cal reactions.

The term “processing station” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to any station of a diagnostic analyzer where a processing step is physically executed such as cen trifugation, aliquotation, sample analysis and the like. Thus, the processing stations include one or more stations selected from the group consisting of: centrifuge, mixer, pipettor, gripper, incubator, shaker, evaporator, vessel tray loader.

The term “memory” as used herein is a broad term and is to be given its ordinary and cus tomary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a device that is used to store information for immediate use in a computer or related computer hardware device. It typically refers to semiconductor memory, specifically metal-oxide- semiconductor (MOS) memory, where data is stored within MOS memory cells on a sili con integrated circuit chip. The term "memory" is synonymous with the term "primary storage". Computer memory operates at a high speed, for example random-access memory (RAM), as a distinction from storage that provides slow-to-access information but offers higher capacities. If needed, contents of the computer memory can be transferred to sec ondary storage; a very common way of doing this is through a memory management tech nique called virtual memory. The term "memory", meaning "primary storage" or "main memory", is often associated with addressable semiconductor memory, i.e. integrated cir cuits consisting of silicon-based MOS transistors, used for example as primary storage but also other purposes in computers and other digital electronic devices. There are two main kinds of semiconductor memory, volatile and non-volatile. Examples of non-volatile memory are flash memory (used as secondary storage) and ROM, PROM, EPROM and EEPROM memory (used for storing firmware such as BIOS). Examples of volatile memory are primary storage, which is typically dynamic random-access memory (DRAM), and fast CPU cache memory, which is typically static random-access memory (SRAM) that is fast but energy-consuming, offering lower memory areal density than DRAM.

The term “processing unit” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a digital circuit which performs operations on some external data source, usually memory or some other data stream. It typically takes the form of a microprocessor, which can be im plemented on a single metal-oxide-semiconductor integrated circuit chip. The term is fre quently used to refer to the central processing unit in a system. However, it can also refer to other co-processors. A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry within a computer that executes instructions that make up a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. Traditionally, the term "CPU" refers to a processor, more specifically to its processing unit and control unit (CU), distinguishing these core elements of a computer from external components such as main memory and I/O circuitry. Most modem CPUs are microproces sors, where the CPU is contained on a single metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. An IC that contains a CPU may also contain memory, peripheral interfac es, and other components of a computer; such integrated devices are variously called mi crocontrollers or systems on a chip (SoC). Some computers employ a multi-core processor, which is a single chip or "socket" containing two or more CPUs called "cores".

The term “interface” as used herein is a broad term and is to be given its ordinary and cus tomary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a shared boundary across which two or more separate components of an electronic system such as a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. Some interfaces may allow hardware devices to both send and receive data through the interface, while others may only provide an interface to send data to a given system. Hardware interfaces exist in many of the components, such as the various buses, storage devices, other I/O devices, etc. A hardware interface is described by the mechanical, electrical and logical signals at the interface and the protocol for sequencing them (sometimes called signaling). A standard interface, such as SCSI, decouples the design and introduction of computing hardware, such as I/O devices, from the design and introduction of other components of a computing system, thereby allowing users and manufacturers great flexibility in the implementation of computing systems. Hardware interfaces can be parallel with several electrical connections carrying parts of the data simultaneously, or serial where data are sent one bit at a time.

The term “power source” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a spe cial or customized meaning. The term specifically may refer, without limitation, to a source of electric power. Electric power is electrical energy which is transferred by an electric circuit and which is usually produced by electric generators or batteries.

The term “internal volume” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a three-dimensional space enclosed by a boundary of a constructional member such as by walls. The term may particularly refer to the space that a constructional member or its shape occupies or contains in its interior. This space may particularly be hollow so as to be configured to receive something. Thus, the internal volume of the reaction vessel may refer to a hollow space within the reaction vessel which is configured to receive the electronic components of the reaction vessel.

As shown in Figure 5, the processing unit 114 communicates with the external electronic device 120 by the interface 118.

Hereinafter, an example for an application of the reaction vessel 100 will be described. The reaction vessel 100 may be used in order to check a functionality of the diagnostic analyzer 106. The reaction vessel 100 is provided. Particularly, the reaction vessel 100 and its elec tronic components, respectively, are switched or powered on. For example, the switching on may be triggered by a command from the external electronic device 120. Further, the reaction vessel 100 is disposed at that processing station 108 of which at least one physical parameter is to be measured. Subsequently, a test process of the diagnostic analyzer 106 is carried out. During the test process of the diagnostic analyzer 106 the at least one physical parameter is measured by the at least one sensor 110. For example, if the reaction vessel 100 is disposed at an incubator, a temperature within the reaction vessel 100 during a test incubation process may be measured by the temperature sensor 136 which substantially corresponds to the temperature within the incubator. The temperature sensor 136 may monitor a temperature, temperature rates, heat transfer through vessel wall 102, a tempera ture distribution if multiple measuring points within reaction vessel 100 are realized. As another example, if the reaction vessel 100 is disposed at a mixer, centrifuge or shaker, g- forces and acceleration during sample mixing and movements may be measured. The ac celerometer 140 detects acceleration, vibration and tilt acting on the reaction vessel 100 to determine movement and exact orientation along the three room axes. The gyroscope 138 can measure additionally rotation. The magnetometer 142 may detect magnetic fields dur ing e.g. magnetic bead sample preparation. The proximity sensor 144 may measure prox imity to outside objects by means of an IR LED and IR detector. The pressure sensor 146 may measure the pressure in the reaction vessel 100 e.g. at a vacuum evaporation station of the diagnostic analyzer 106. Basically, the physical parameter may be at least one parame ter selected from the group consisting of: position of the reaction vessel, orientation of the reaction vessel, acceleration acting the reaction vessel, g-forces acting on the reaction ves sel, vibration acting on the reaction vessel, tilt of the reaction vessel, rotation of the reac tion vessel, magnetic field acting on the reaction vessel, proximity to an object outside of the reaction vessel, pressure on or within the reaction vessel, humidity within the reaction vessel, temperature within the reaction vessel, concentration of a fluid, particularly a liq uid, within the reaction vessel.

A measurement value indicating the physical parameter measured by the sensor 110 can be at least temporarily stored in the memory 112. After the test process, measurement data including the measurement value are output from the memory 112 to the external electron ic device 120. The output may be triggered by a corresponding command from the external electronic device 120. Alternatively, the measurement data may be output in real time. The measurement data may be output by means of the interface 118. Particularly, the measure ment data may be output in a wired or wireless manner. Subsequently, the measurement data are compared with target data. The comparing step may be carried out by the external electronic device 120. A proper functionality is determined if comparing the measurement data with target data reveals a difference smaller than or equal to a predetermined thresh old. On the other hand, an improper functionality is determined if comparing the measure ment data with target data reveals a difference greater than the predetermined threshold. For example, if measurement data including a measurement value for a temperature meas ured by the temperature sensor 136 of the reaction vessel 100 during presence in an incu bator reveal a difference from a target temperature value being smaller than a predeter mined threshold, it can be concluded that a deviation of the actual temperature from a tar get temperature is smaller than a predetermined threshold. Thus, the actual temperature is within an acceptable range for the temperature meaning that the incubator properly works. Needless to say, the test process may be repeated a predetermined time and an average value of the measurement data may be calculated. In this case, an improper functionality is determined if comparing the average of the measurement data with the target data reveals a difference greater than the predetermined threshold. If the reaction vessel 100 comprises the optional light receiver, the method may further include detecting light emitted by a light source associated with a component of the diag nostic analyzer 106. Thus, the method may further comprise adjusting the orientation and/or position of the component of the diagnostic analyzer 106 based on the detected light. For example, the light receiver is a camera and may be used in order to detect light emitted from a light source mounted to a pipettor so as to check whether the pipettor moves correctly to a target position. The check of the position of the pipettor may be based on the amount, angle and/or position and/or wavelength of light incident on the light re ceiver. If a deviation of the pipettor from its target position is detected, the pipettor may be adjusted in its position so as to allow a proper pipetting process. Alternatively or in addi tion, the light receiver may detect light reflected from a component of the diagnostic ana lyzer 106. In this case, the reaction vessel may further comprise a light source.

Figure 6 shows a front view of electronic components of a reaction vessel 100 according to a second embodiment of the present invention. Hereinafter, only the difference from the reaction vessel 100 according to the first embodiment are described and like constructional members are indicated by like reference numerals. Rather than the at least one sensor 110, the reaction vessel 100 of the second embodiment comprises a light receiver 160. The light receiver 160 may particularly be a camera device such as a micro CCD camera. The reac tion vessel 100 is configured to be used with a diagnostic analyzer 106 comprising a plu rality of processing stations 108.

The memory 112 is configured to at least temporarily store at least one measurement value indicating the detected light provid- ed by the light receiver 160. The processing unit 114 is configured to control the light re ceiver 160 and to output measurement data including the measurement value from the memory 112. Particularly, the processing unit 114 is configured to determine an orientation and/or position of the component 162 associated with at least one of the processing stations 108 of the diagnostic analyzer 106 based on the measurement value. The orientation and/or position of the component 162 includes a position of the component 162 and/or an angle of the component with respect to a reference object such as a target pipetting path. For exam ple, the light receiver 160 is used in order to detect light emitted from the light source 164 mounted to the pipettor so as to check whether the pipettor moves correctly to a target po sition. The check of the position of the pipettor may be based on the amount, angle, wave length and/or position of light incident on the light receiver 160. If a deviation of the pipet tor from its target position is detected, the pipettor may be adjusted in its position in all directions of the three dimensional space so as to allow a proper pipetting process. Alterna tively or in addition to the light receiver, the reaction vessel may comprise an ultrasonic detector configured to detect and/or emit ultrasound in order to determine an orientation and/or position of the component 162 associated with at least one of the processing stations 108 of the diagnostic analyzer 106.

For this purpose, the diagnostic analyzer 106 comprises an adjusting device 166. The ad justing device 166 is configured to adjust an orientation of the component 162 according to a target orientation based on measurement data output from the processing unit 114 to the external electronic device 120. The adjusting device may be a xyz-stage or the like config ured to move the pipettor along all three axis of a room. The external electronic device 120 is configured to be connected to the adjusting device 166 or may be part of the diagnostic analyzer 106. Particularly, the external electronic device 120 is configured to calculate a deviation of an actual orientation of the component 162 from the target orientation and to provide orientation correction data to the adjusting device 166. The adjusting device 166 is configured to adjust the actual orientation of the component 162 to the target orientation based on the orientation correction data.

Hereinafter, an example for an application of the reaction vessel 100 will be described. The reaction vessel 100 may be used in order to determine an orientation the component 162 associated with at least one of the plurality of processing stations 108 of the diagnostic analyzer 106. The reaction vessel 100 of the second embodiment is provided. The electron ic components are switched or powered on such as by means of a command from the ex ternal electronic device 120. The reaction vessel 100 is disposed at the processing station 108 of which the orientation is to be determined. The light source 164 of the component 162 emits light towards the light receiver 160. The light emitted from the light source 164 of the component 162 associated with at one of the processing stations 108 is detected by means of the light receiver 160. A measurement value indicating the detected light provid ed by the light receiver 160 is at least temporarily stored in the memory 112. Measurement data including the measurement value are output from the memory 112 to the external elec tronic device 120. The output may be triggered by a corresponding command from the external electronic device 120. Alternatively, the measurement data may be output in real time. Subsequently, an orientation of the component 162 associated with at least one of the processing stations 108 of the diagnostic analyzer 106 is determined based on the meas urement value. The orientation of the component 162 includes a position of the component 162 and/or an angle of the component 162 with respect to a reference object. For example, the light receiver 160 detects an amount, a position and/or an angle and/or a wavelength of the light incident thereon. The external electronic device 120 may calculate the orientation of the component 162 based on the measurement data including the measurement value which corresponds to the amount, a position and/or an angle and/or a wavelength of the light incident on the light receiver 160. Further, an actual orientation of the component 162 associated with at least one of the processing stations 108 of the diagnostic analyzer 106 is adjusted to a target orientation based on the measurement value. The adjusting of the orien tation of the component 162 to its target orientation is carried out by the adjusting device 166 communicating with the external electronic device 120. Needless to say, the reaction vessel 100 may be disposed at more than one processing station. For example, the reaction vessel 100 may follow all processing stations a normal sample tube passes, i.e. the reaction vessel 100 starts with being disposed in the vessel tray and is returned therein at the end.

The control of the orientation of the component can be performed using a software running on the external electronic device 120 with feedback loops. A more specific task in adjust ing vessel handling devices is the adjustment of the height of the component, i.e. along a z- axis. Here the usage of the physical phenomena of induction can help. Using different in duction coils integrated into the reaction vessel 100, the height of the component can be measured and consequently be used for adjustment. A reaction vessel 100 made of metal in combination with using already in place technology such as liquid level detection corre sponding to conductivity of the pipettors can be used to improve adjustment procedures. Two scenarios are feasible. A small pin on top of the metal reaction vessel 100 can be a precise contact point for adjustment and inform the field service engineer either by a) sound or b) visual information such as a LED. Adjustment can this way be semi automat ed, wherein the field service engineer sees and/or hears with increased frequency when he arrives at the aimed position such as similar to a car parking system. In addition or alterna- tively, ultrasonic detection for height measurements similar to parking help for cars can be used. Alternatively, a fix point for LIDAR can be applied.

Figure 8 shows a flowchart of an example for a method for detecting physical parameters at the diagnostic analyzer 106 by means of the reaction vessel 100. This method can par ticularly be carried out by using the reaction vessel 100 according to the first embodiment. Particularly, Figure 8 shows the reaction vessel 100 disposed at the diagnostic analyzer 106. Further, Figure 8 shows an external electronic device 120. The external electronic device 120 comprises a wireless network such as BLE, WiFi, RFID reader and the like. The external electronic device 120 further comprises a microprocessor including a clock and simple logics. The external electronic device 120 further comprises a data storage hav ing a fast enough writing speed. The external electronic device 120 further comprises an optional interface to the diagnostic analyzer for trigger reception and commands. The ex ternal electronic device 120 further comprises an optional interface to an external data pro cessing unit for live transmission of signals, dashboards, warnings and the like. The exter nal electronic device 120 may communicate with an external device 168 for data viewing and treatment which may be connected to an external microcontroller. The external device 168 comprises visualization means such as monitor, display, and the like. The external device 168 allows a live comparison to defined thresholds for warning, live representation of the diagnostic analyzer status and run status. It is explicitly stated that the external elec tronic device 120 and the external device 168 could be provided in one solution, i.e. inte grated into one device, e.g. as a tablet with compatible Bluetooth interface and protocols).

The method starts with one or more reaction vessel 100 disposed at the diagnostic analyzer 106 which has programmable run parameters. In step S10, the at least one reaction vessel 100 is put on or gets on a rack carrying the same. In a subsequent step S12, the operator starts a service run or test process. In a subsequent step S14, the diagnostic analyzer 106 starts the run. In a subsequent step SI 6, a movement of the reaction vessel 100 is per formed through one or more processing stations 108 and the positions of the reaction ves sel 100 from the perspective of the diagnostic analyzer 106 is flagged with time stamps. During the movement, the reaction vessel 100 obtains the physical measurement data by means of its sensors 110 such as g-forces, pressure, temperature and the like as described above. In a subsequent step SI 8, the diagnostic analyzer 106 terminates the run. In a sub sequent step S20, the operator terminates the service run or test process. In a subsequent step S22, the operator removes the at least one reaction vessel 100 from the diagnostic ana lyzer 106. As is further shown in Figure 8, following step S14 in which the diagnostic analyzer 106 starts, in step S24 logging of measurement data from the sensor 110 of the reaction vessel 100 starts which is initiated by a first software trigger 170 and/or a first sensor trigger 172 such as a movement of the reaction vessel 100. Subsequently, the method proceeds to step S26 in which a transmission of the logged measurement data from the sensors 110 together with a timestamp is carried out with a frequency of at least 1 Hz. In subsequent step S28, the logging of measurement data from the sensor 110 of the reaction vessel 100 is termi nated. As is further shown in Figure 8, following step S18 in which the diagnostic analyzer 106 terminates the run, the method also proceeds to step S28 in which the logging of measurement data from the sensor 110 of the reaction vessel 100 is terminated, which is initiated by a second software trigger 174 and/or a second sensor trigger 176 such as a sen sor 110 without a change of its signal, e.g. no movement of the reaction vessel 100.

Figure 9 shows a flowchart of an example for determining an orientation of a component of the diagnostic analyzer by means of the reaction vessel. This method can particularly be carried out by using the reaction vessel 100 according to the second embodiment. Particu larly, Figure 9 shows the reaction vessel 100 disposed at the diagnostic analyzer 106. Here inafter, only the differences from the method shown in Figure 8 will be explained and like constructional features are indicated by like reference numerals. Particularly, the construc tion of the external electronic device 120 and the external device 168 is identical to the one shown in Figure 8.

The method starts with one or more reaction vessel 100 disposed at the diagnostic analyzer 106 which has programmable run parameters. In step S50, the at least one reaction vessel 100 is put on or gets on a rack carrying the same. In a subsequent step S52, the operator starts a service run or test process. In a subsequent step S54, the diagnostic analyzer 106 starts an adjustment run with the reaction vessel 100 being on a first adjustment position n. As is further shown in Figure 9, following step S54 in which the diagnostic analyzer 106 starts the adjustment run, in step S56 logging of measurement data from the sensor 110 of the reaction vessel 100 starts which is initiated by a first software trigger 170 and/or a first sensor trigger 172 such as a movement of the reaction vessel 100. As is further shown in Figure 9, there is a feedback loop 178 between step S56 and a step S58 in which the orien tation such as a position of a component of the diagnostic analyzer 106 such as a pipettor is checked against a reference point in a database of the diagnostic analyzer 106. During the feedback loop, in parallel step S60 a transmission of the logged measurement data from the sensors 110 together with a timestamp is carried out with a frequency of at least 1 Hz and a stepwise correction of the orientation or position of the component of the diagnostic ana lyzer 106 is carried out. If it is determined that the position of the component of the diag nostic analyzer 106 does not match with the reference point, i.e. there is a deviation of the actual position of the component from the target position thereof, the method returns from step S58 to step S56 and the logging of measurement data from the sensor 110 of the reac tion vessel 100 continues. If in step S58 it is determined that the position of the component of the diagnostic analyzer 106 matches with the reference point, i.e. there is no deviation of the actual position of the component from the target position thereof, the method proceeds to step S62 in which the diagnostic analyzer 106 starts an adjustment run with the reaction vessel 100 being on a second adjustment position n+1. Subsequently, steps S56 to S60 are repeated as described before. The, the method proceeds to step S64 in which the diagnostic analyzer 106 starts an adjustment run with the reaction vessel 100 being on a further ad- justment position n+x. Subsequently, steps S56 to S60 are repeated as described before. If all adjustment runs have been completed, the method proceeds to step S66 in which the diagnostic analyzer 106 terminates the run. In a subsequent step S68, the operator termi nates the service run or test process. In a subsequent step S70, the operator removes the at least one reaction vessel 100 from the diagnostic analyzer 106. As is further shown in Fig- ure 9, if the service run includes a position check of only one adjustment position, the method may proceed from step S58 to step S68.
