PURPOSE: To provide a method and apparatus for measuring ATP quantity of cell which enables the ATP (adenosine triphosphate) quantity of cells to be measured with high precision dispensing with the operation of folding a filter membrane after cell trap and not only improving operability but also solving the dangerousness of contamination from outside the filter membrane.
CONSTITUTION: A filter membrane 100 which has trapped cells in a specimen is placed in a one-sided open tray container 200 without being folded. The container 200 is injected with an extraction reagent 104 and a luminous reagent to cause biochemical luminous reaction. A photomultiplier tube 108 is installed so as to face the opening of this container 200 to detect the luminous quantity, resulting in measurement of the ATP quantity of cells.
