摘要： A method of immunologically examining a specimen which comprises attaching a cap having a filter impregnated with a labeled antibody enclosed therein to a container body containing a diluted liquid specimen, pouring the diluted liquid specimen from the container into a test device, observing the reaction and thus examining the presence or absence of an analyte in the specimen. This examination method, whereby effects of differences among individual operators can be minimized and the occurrence of a nonspecific reaction can be prevented, is highly excellent in the reproducibility of the examination results and storage stability of a test reagent. A specimen container to be used in the above method to which a cap having a filter impregnated with a labeled antibody enclosed therein is attached. This container is appropriately usable as a member constituting a simplified diagnosis kit.

Then, the amount of the resultant reduced colored substance is measured. As the 1,5-anhydroglucitol dehydrogenase, an enzyme produced by a microorganism having the ability to produce the 1,5-anhydroglucitol dehydrogenase is preferably used.
