Reiter haemagglutination test: a screening test for syphilis.

Using an ultrasonicate of the Reiter treponeme as antigen the Reiter haemagglutination test (RHA) was evaluated as a serological test for syphilis. Comparison of the results of the cardiolipin Wassermann reaction, Reiter protein complement-fixation test, the fluorescent treponemal antibody-absorbed (FTA-ABS) test, the Treponema pallidum haemagglutination test (TPHA) (at dilutions of 1/16 and 1/...

Simplified method for the rubella haemagglutination inhibition screening test.

A modification of the rubella haemagglutination inhibition (HAI) test in which both pretreatment and serum titration are carried out in wells of the same microtitre plate saves time, labour, and materials and gives results comparable to a conventional HAI procedure.

Treponema pallidum haemagglutination test as a screening procedure for the diagnosis of syphilis.

The serological diagnosis of syphilis relies upon the widespread use of non-specific screenig tests, such as the cardiolipin Wassermann reaction (CWR) and the Venereal Diseases Research Laboratory (VDRL) slide test, in combination with the Reiter protein complement-fixation (RPCF) test (British Cooperative Clinical Group, 1972). Where necessary, the fluorescent treponemal antibody-absorbed (FTA...

Treponema pallidum specific IgM haemagglutination test for serodiagnosis of syphilis.

The Treponema pallidum specific IgM haemagglutination (TP-IgM-HA) test uses erythrocytes sensitised with antiserum to human IgM to separate IgM from IgG in serum. Specific antitreponemal IgM captured in this way is detected by adding a second reagent comprising erythrocytes sensitised with T pallidum antigen. Eighty two serum samples from 82 patients with untreated syphilis, 521 samples from 73...
