Test Code:
RPR (Montior) w/ Reflex to Titer: 799
CPT Code(s):
RPR (Montior) w/ Reflex to Titer: 86592
Methodology: Flooculation
Clinical Significance:
RPR (Monitor) w/ Reflex to Titer: 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 and 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.
False positive results with nontreponemal (lipoidal antigen) test may occur due to wide range of biological conditions (e.g., autoimmune disease, cancer, infectious disease, old age, and pregnancy).
Includes:
RPR (Monitor) w/ Reflex to Titer: If RPR Screen is reactive, RPR titer will be performed at an additional charge (CPT code(s): 86593).

Rejection Criteria:
- Contact DLO's Customer Service for specific criteria.
- Hemolysis
- What are hemolyzed specimens?
- Hemolysis occurs when the red cells are damaged during sample collection causing them to rupture. Hemolyzed serum or plasma is pale pink to red rather than the normal clear straw or pale-yellow color.
- What causes a specimen to be hemolyzed?
- Mixing tubes too vigorously
- Placing tubes in the refrigerator without allowing 30 minutes at room temperature for complete clotting
- Exposure to heat or in a refrigerator that is too cold
- Using a needle with too small of a bore necessary for the venipuncture
- Using too large a tube when using a butterfly needle
- Not allowing sufficient time for alcohol to dry on puncture site
- Leaving the tourniquet on for longer than one minute
- How can hemolyzed specimens be prevented?
- For routine collections, use a 20–22-gauge needle
- Do not remove the needle from the vein with the vacuum tube engaged
- Do not collect a specimen in a hematoma
- Do not centrifuge the specimen for a prolonged period of time
- Draw the sample gently and evenly
- What are hemolyzed specimens?
- Specimens exceeding stability
- Specimens other than serum
- Unlabeled or improperly labeled specimens
