Patent ID: 7267802

Claim:
A method for correcting measurement data for carrying out a correction in accordance with a deterioration of a reagent over time with respect to the measurement data measured by using a reagent carrier that carries a reagent in accordance with items to be measured, and an information indicator, in which reagent information including information necessary to designate a lot and a date of manufacture is recorded, being attached to the reagent carrier, the method comprising: designating a deterioration correction data table corresponding to the lot of the reagent carrier used for measurement in the deterioration correction data table containing deterioration indices showing a deterioration of a reagent over time from the date of manufacture to an expiration date at plural time points on a time series for each lot of the reagent carrier based on the reagent information obtained from the information indicator of the reagent carrier used for measurement, extracting the deterioration indices at a preceding time point and a following time point of a measurement date of the measurement data in the deterioration indices recorded in the designated deterioration correction data table, calculating a deterioration index by interpolation at the measurement date based on the deterioration indices at the preceding and following time points extracted, and carrying out a deterioration correction of the measurement data based on the calculated deterioration index.
