Classification: CPC G | IPC G

Claim 1:
2. An analysis method comprising:
a step of dispensing a sample into a first standby position;
a step of inputting analysis contents by an operator relating a type of analysis to be performed on to a sample;
a first determination step of determining whether a reaction inhibitor having a chemical structure similar to a binding site of the first reagent to the third reagent is expected to be present in the sample based on the inputted analysis contents, wherein if the reaction inhibitor is not expected to be present, the sample is dispensed from the first standby position to a first reaction vessel according to a first reaction process and, if the reaction inhibitor is expected to be present, the sample is dispensed from the first standby position to a second reaction vessel or a second standby position according to a second reaction process;
a step of, upon determining that the reaction inhibitor is expected to be present, performing the first reaction process which includes mixing the sample from the first standby position, a first reagent comprising a biotinylated antibody, and a second reagent comprising a labelled antibody including a substance emitting light detectable by the measurement unit in the first reaction vessel, for measuring a mixed solution of the sample and the first reagent to prepare a first mixed solution, and, after a lapse of predetermined time, mixing a third reagent, which comprises insoluble carriers carrying an antibody or antigen on a particle surface having a binding specificity for the first reagent, and the first mixed solution to prepare a second mixed solution in the first reaction vessel;
a step of, upon determining that the reaction inhibitor is not expected to be present, performing the second reaction process which includes mixing the first reagent and the third reagent to prepare a third mixed solution in a first reaction vessel, and, after a lapse of predetermined time, mixing the sample from the second reaction vessel or a second standby position, the second reagent, and the third mixed solution to prepare a fourth mixed solution;
a measurement step of measuring the second mixed solution or the fourth mixed solution; and
a second determination step of determining whether a result measured in the measurement step is within a predetermined range determined in advance based on the analysis contents, wherein
if the first reaction process is performed and the determination result is not within the predetermined range determined in advance based on the analysis contents in the second determination step, performing the second reaction process.
