Abstract

A specimen analyzing method and a specimen analyzing apparatus capable of measuring interference substances before analyzing a specimen. The method comprises a step for sucking the specimen stored in a specimen container ( 150 ) and sampling it in a first container ( 153 ), a step for optically measuring the specimen in the first container, a step for sampling the specimen in a second container ( 154 ) and preparing a specimen for measurement by mixing the specimen with a reagent in the second container, and a step for analyzing the specimen for measurement according to the results of the optical measurement of the specimen.

First claim
