Evaluation of a Hemagglutination Test for Human Leptospirosis [PDF]
Applied Microbiology, 1973 An indirect hemagglutination test for the diagnosis of leptospirosis is described; the test uses a soluble antigen from serotype patoc to sensitize sheep erythrocytes which are then fixed with glutaraldehyde. Evaluation of this procedure indicates that it is more reliable than the conventional macroscopic agglutination test and, in contrast with both ...

An Improved Diluent for Rubella Hemagglutination and Hemagglutination-Inhibition Tests [PDF]
Applied Microbiology, 1968 Rubella hemagglutinating (HA) antigen was prepared in BHK-21 tissue as 5% cell suspensions and from unconcentrated and 20× concentrated infected supernatant fluids. In some instances, unconcentrated fluids were treated with Tween 80 and ether; cell suspensions were treated with ether alone.

Hemagglutination treponemal test for syphilis [PDF]
Journal of Clinical Microbiology, 1983 Sera from 290 hospital patients were tested to compare the sensitivity, specificity, and reproducibility of the hemagglutination treponemal test for syphilis (HATTS) with the fluorescent treponemal antibody absorption test (FTA-ABS). Complete agreement was obtained between the methods when 142 syphilitic sera from patients with various stages of ...
