rap·id plas·ma re·a·gin test

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.
Persons who were treated in the past are considered to have a new syphilis infection if quantitative testing on an RPR test or another nontreponemal test reveals a four fold or greater increase in titer (health departments maintain registries of past positive tests).
As with the RPR test, patients whose ulcerations were only MPCRTP positive had a higher FTA-ABS seropositivity rate than those with other aetiologies recorded (96.
Among the many serologic tests available, the RPR test and FTA-ABS test are the most widely employed.
While non-treponemal tests (NTTs), VDRL test and RPR tests are used for screening, follow-up and treatment, treponemal tests are used to verify the diagnosis (7).
ESPLINE TP and RPR tests have been validated for use in OWPs (11).
