TPHA test

Trep·o·ne·ma pal·li·dum he·mag·glu·ti·na·tion test

a highly sensitive and specific test for the serologic diagnosis of syphilis; tanned sheep red blood cells are coated with the antigen of T. pallidum and, after absorption of nonspecific patient serum antibody, a positive reaction with tanned sheep red blood cells and patient serum indicates the presence of specific antibody for T. pallidum in patient serum.

The TPHA test detects antibodies against a specific treponemal antigen.
To contribute to the scant data on syphilis screening and prevalence in psychiatric patients, we aimed: (i) to determine and compare the prevalence of syphilis among different psychiatric inpatient groups; (ii) to determine and compare the psychiatric diagnoses of syphilis-infected and -uninfected patients; (iii) to assess self-reported high-risk sexual behaviour among patients; (iv) to establish the syphilis/HIV co-morbidity among patients; (v) and to investigate the performance of the non-treponemal RPR test as a screening method compared with the confirmatory treponemal-specific TPHA test.
Compared with the TPHA test, the RPR test performed poorly, identifying only 2/23 patients who had syphilis.
The RPR test had an unacceptably low sensitivity as a syphilis screening procedure, indicating a low syphilis prevalence of only 1% (the TPHA test indicated a prevalence of 11.
The participants were screened for syphilis with the RPR and TPHA tests.
A TPHA test was performed in every case to rule out cross-reacting antibodies to Treponema pallidum.
The aims of this study were to determine and compare the prevalence of syphilis among different patient groups at Weskoppies Hospital, to determine and compare the psychiatric diagnoses of the infected and non-infected, to assess self-reported high-risk sexual behaviour, to establish the co-morbidity between syphilis and HIV, and to investigate the performance of the non-treponemal RPR test as screening method, compared with the confirmatory TPHA test.
A reactive TPHA test indicative of exposure to syphilis, although not necessarily of active disease, was used to diagnose syphilis.
Significant co-morbidity occurred between HIV and syphilis, with 7 of the 24 HIV infected patients also having reactive TPHA tests (p=0.
