RPR with Reflex to TPPA

Test Summary

RPR: This is a non-treponemal screening test for syphilis. False positive results may occur due to systemic lupus erythematosus, malaria, mononucleosis, infectious hepatitis, leprosy, brucellosis, atypical pneumonia, typhus, yaws, pinta, or pregnancy. Positive results should be confirmed with a more specific treponema pallidum antibody test (FTA-ABS). Monitoring of RPR is helpful in assessing effectiveness of therapy. The reflex TPPA test is designed to be used as an aid in the confirmation of antibodies to the Treponemal organisms that cause Syphilis. .
