To provide an examination method of blood capable of conserving examination labor as a whole and capable of making the constitution of an examination apparatus more compact in an examination method performing biochemical examination and/or immune serum examination and blood coagulation examination in parallel.

In an examination method of blood, a sample in each of reaction containers C is analyzed by an optical machinery 2 while a large number of the reaction containers C are moved by a feed means. By the control of the feed means, the distribution operation of the sample or reagent, the reciprocal moving operation for moving the reaction containers C in forward and rearward directions by a predetermined number of times and slow speed feed operation for moving the reaction containers C are performed and, at a time of the reciprocal moving operation, the intensity of transmitted or scattered light from the sample in each reaction container C is detected at the photometric interval corresponding to reaction by the optical machinery 2.
