Details
RPR (Diagnosis) with Reflex to Titer and Treponema pallidum Antibody, IA - This test is used to aid in the diagnosis of syphilis using the traditional algorithm. Testing can be performed for individuals suspected of syphilis based on signs and symptoms or for screening asymptomatic individuals. Screening is recommended in certain populations at increased risk for infection and pregnant women.
Reflex testing uses predefined clinical logic to automatically order one or more follow-up tests based on the initial test results. Reflex tests are performed automatically without the intervention of the ordering practitioner. They are conducted using the same sample your Patient already provided. If reflex tests are required, there will be additional charges.
Initial test
- RPR (Reagin Ab)
Possible reflex biomarkers
- Treponema Pallidum Ab
- RPR Titer
Estimated days for results: Results should be available in 2 - 5 business days after the sample is collected
Testing can be performed for individuals suspected of syphilis based on signs and symptoms or for screening asymptomatic individuals. Screening is recommended in certain populations at increased risk for infection and pregnant women.
False positive results with nontreponemal (lipoidal antigen) test results may occur due to wide range of biological conditions (e.g., autoimmune disease, cancer, infectious diseases, old age, and pregnancy). False negatives can occur in persons with recent exposure. Persons with previously treated syphilis will remain positive using a treponemal test. Therefore, a single type of serological test is insufficient for diagnosis and positive result using a nontreponemal (lipoidal antigen) test should be confirmed by a treponemal specific assay using the traditional algorithm.
