Using an ultrasonicate of the Reiter treponeme as antigen the Reiter haemagglutination test (RHA) was evaluated as a serological test for syphilis.

Simplicity, sensitivity, availability of the antigen, and the very low cost of this test support its use as a first-line screening test for syphilis. Reiter treponemes (seeding cultures received from Wellcome Company) were grown on Christiansen's'5 modification of Brewer's thioglycollate medium with the omission of agar and resazurin: trypticase 15 g,
