Call (877) 731-6362 to schedule your test today. --- Syphilis test how it works involves collecting a blood sample, sending it to a national lab network for screening and confirmation, and a certified Medical Review Officer reviews non-negative results. This process ensures accuracy and compliance. Call (877) 731-6362 to arrange your syphilis test. COLLECTION ## How is the sample collected for a syphilis test? The syphilis test sample is collected through a blood draw at an authorized collection site. AMH Nationwide directs the requester to one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox. A trained phlebotomist performs the blood draw following standard procedures to ensure sample integrity. LAB ANALYSIS ## How does the lab analyze the syphilis test sample? Once collected, the blood sample is sent to the designated national lab for initial screening. The screening typically uses immunoassays to detect antibodies related to Treponema pallidum, the bacteria causing syphilis. If the screening result is reactive, the lab performs a confirmatory test, such as the fluorescent treponemal antibody absorption (FTA-ABS) or the Treponema pallidum particle agglutination (TP-PA) test, to verify the presence of infection. PROCESS STEPS ## What are the steps from screening to confirmation in a syphilis test? The syphilis test process includes two main phases: screening and confirmation. First, the screening detects possible syphilis antibodies. If the screening is non-reactive, the test is reported negative. If reactive, the sample undergoes confirmatory testing to rule out false positives. Confirmatory tests use different methods to specifically identify syphilis antibodies, ensuring the diagnosis is accurate. Screening: Initial immunoassay detects syphilis antibodies Confirmatory: Secondary test verifies positive screening results Negative screen: No further testing needed Positive screen: Proceed to confirmation testing MRO REVIEW ## What role does the Medical Review Officer play in syphilis test results? Every non-negative syphilis test result is reviewed by a certified Medical Review Officer (MRO) as part of the standard process. The MRO evaluates the laboratory findings in the context of the individual’s medical history and any relevant information. This review ensures that positive results are valid and that any potential false positives or clinical considerations are addressed before final reporting. ## Ready to Get Your Syphilis Test?

The exact turnaround time depends on the lab network and confirmatory testing if needed. The syphilis test involves a standard blood draw, which may cause minor discomfort similar to any routine venipuncture. Syphilis tests detect antibodies, which may take several weeks to develop after infection. Early infection might not be detected immediately, so follow-up testing may be recommended. If the test is positive after confirmation, the Medical Review Officer reviews the result and advises on next steps, which may include consultation with a healthcare provider for treatment. Yes, all syphilis test results processed through AMH Nationwide and its lab partners are handled with strict confidentiality and privacy protections. No fasting or special preparation is required before a syphilis blood test.
