A Rapid Plasma Reagin (RPR) test is a blood test used to screen for syphilis, a sexual transmitted disease.

Clinical Significance:

The Rapid Plasma Reagin (RPR) with Reflex to titer, is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis.

This is a non-treponemal screening test for syphilis, a sexual transmitted disease. False positive results may occur due to systemic lupus erythematosus, leprosy, brucellosis, atypical pneumonia, typhus, yaws, pinta, or pregnancy. Monitoring of RPR is helpful in assessing effectiveness of therapy.

If RPR Screen is reactive, then RPR titer will be performed at an additional charge.
