IMMUNODIAGNOSTIC TEST CARDS HAVING INDICATING INDICIA

摘要

An immunodiagnostic test card includes a plurality of transparent chambers wherein each chamber includes a quantity of testing material that combines with a patient sample, when mixed, to produce an agglutination reaction. A plurality of indicia are disposed to aid in the manufacture and determining the usability of the cards prior to test and also in objectively grading the agglutination reactions that are formed or lack of agglutination.
