Reiter haemagglutination test: a screening test for syphilis
The British Journal of Venereal Diseases
|October 1, 1982
Summary
The Reiter haemagglutination test (RHA) shows promise as a sensitive and cost-effective first-line screening tool for syphilis. This serological test demonstrated high agreement with established methods, supporting its potential for widespread use.
Area of Science:
- Medical Microbiology
- Immunology
- Public Health
Background:
- Syphilis serology relies on various diagnostic tests to detect infection.
- Established tests include Wassermann, Reiter protein complement-fixation, FTA-ABS, TPHA, and VDRL.
- There is a need for sensitive, cost-effective screening methods for syphilis.
Purpose of the Study:
- To evaluate the Reiter haemagglutination test (RHA) as a serological diagnostic for syphilis.
- To compare the RHA's performance against established syphilis serological assays.
- To assess the RHA's suitability as a primary screening tool.
Main Methods:
- The Reiter treponeme was used as an antigen for the RHA.
- RHA results were compared with cardiolipin Wassermann reaction, Reiter protein complement-fixation, FTA-ABS, TPHA, and VDRL tests.
- Sensitivity and agreement with other tests were calculated.
Main Results:
- The RHA demonstrated a sensitivity of 85.8%.
- The RHA showed 85.8% agreement with the fluorescent treponemal antibody-absorbed (FTA-ABS) test.
- The Reiter haemagglutination test exhibited high concordance with multiple established syphilis tests.
Conclusions:
- The Reiter haemagglutination test is a sensitive serological assay for syphilis.
- Its simplicity, antigen availability, and low cost support its use as a first-line screening test.
- The RHA offers a viable alternative for syphilis detection, particularly in resource-limited settings.
