A direct agglutination assay is taught which provides increased sensitivity when assaying analytes which lack repeating epitopes. In this assay the sample is divided into portions which are separately reacted with different but complementary agglutination reagents and then recombined so that agglutination may occur. Increased sensitivity is obtained.
