ABSTRACT:
A method of distinguishing between strips for different assays in an automated instrument, wherein characteristics to which the instrument is sensitive are selectively introduced in microwells of individual microstrips which are pretreated with a specific antigen or antibody for a particular test. On each microstrip, the wells having the characteristic collectively define a multi-bit code which corresponds to a particular condition or disease to be tested for. The automated instrument reads the characteristic from the selected wells and thus determines what test is to be conducted. The marks may have optical, radioactive, luminescent, fluorescent, or magnetic characteristics, in accordance with the test to be conducted.
