Common<unk> c tests used routinely include:
Venereal Disease Research Laboratory (VDRL),
Rapid plasma reagin (RPR), or
Recombinant antigen test
Sensitivity of<unk> c tests vary with the disease stage.
78-86% sensitivity for primary syphilis
100% sensitivity for secondary syphilis
95-98% sensitivity for tertiary syphilis
Specificity is aprroximately 85-99%
False positives on the rapid tests can be seen in viral infections (Epstein-Barr, hepatitis, varicella, measles), lymphoma, tuberculosis, malaria, endocarditis, connective tissue disease, pregnancy, intravenous drug abuse, or contamination. As a result, these two screening tests should always be followed up by a more specific treponemal test.
