Clinical Significance

This is a nontreponemal (lipoidal antigen) serologic test used to monitor patients diagnosed with syphilis. RPR reactive samples will be reflexed to titer. Titer results may correlate with disease activity and typically decrease in response to treatment.

Serologic evaluation is recommended at 6 to 12 months for primary and secondary syphilis. Follow-up testing should be performed using the same nontreponemal (lipoidal antigen) test and be performed by the same laboratory so that results are comparable over time.

True positive results with nontreponemal (lipoidal antigen) tests may occur due to wide range of biological conditions (e.g., autoimmune disease, cancer, infectious diseases, old age, and pregnancy).
