Book Syphilis Test: Purpose, Normal Range and Price

The Syphilis test is a blood test that detects antibodies produced by the immune system in response to infection with Treponema pallidum, the bacterium that causes syphilis. Modern syphilis testing at NABL-accredited laboratories uses treponemal antibody detection methods including TPHA, CMIA, or ELISA-based assays that directly detect antibodies against the syphilis bacterium itself, making them highly specific and sensitive for confirming syphilis infection. This is distinct from older non-treponemal screening tests such as VDRL and RPR, which detect reagin antibodies as a proxy for infection and require treponemal confirmation. Syphilis is a re-emerging sexually transmitted bacterial infection in India with rising case numbers particularly in urban populations, among men who have sex with men, and in antenatal care settings. Left untreated, syphilis progresses through primary, secondary, latent, and tertiary stages over years, causing serious complications including cardiovascular syphilis, neurosyphilis, and permanent organ damage. Congenital syphilis from untreated maternal infection causes stillbirth, neonatal death, and severe developmental complications. Syphilis is entirely curable with a single dose of penicillin in early stages, making early detection through testing critically important. The test involves a simple blood draw completed in under five minutes.

Doctors prescribe a Syphilis test in the following situations: Screening sexually active individuals with new or multiple sexual partners, genital ulcers, skin rashes, or other symptoms suggestive of sexually transmitted infection where early detection allows curative penicillin treatment before disease progression to later irreversible stages. Routine antenatal screening in all pregnant women as mandated by Indian maternal health guidelines, where early detection and treatment of maternal syphilis prevents vertical transmission to the foetus and eliminates the risk of congenital syphilis, stillbirth, and neonatal complications. Investigating secondary syphilis in patients with a generalised skin rash including characteristic involvement of the palms and soles, mucous membrane lesions, condylomata lata, and generalised lymphadenopathy where treponemal antibody testing confirms the diagnosis. Diagnosing latent syphilis in patients with no current symptoms but with a history of untreated or inadequately treated STI, where a reactive treponemal test detects persistent antibodies confirming past or ongoing infection requiring treatment. Investigating neurosyphilis in patients with unexplained neurological symptoms, psychiatric manifestations, cranial nerve palsies, or cerebrospinal fluid abnormalities where syphilis must be excluded as a treatable and reversible underlying cause. Screening individuals diagnosed with other sexually transmitted infections including HIV, gonorrhoea, and chlamydia where syphilis co-infection is common and significantly alters management, particularly in HIV-positive patients where syphilis behaves more aggressively. Pre-marital and pre-operative screening as part of routine infectious disease blood investigations where syphilis testing is included in several Indian state protocols and institutional pre-operative panels.

The Syphilis test detects the presence or absence of treponemal antibodies against Treponema pallidum in the blood. Results are reported as Reactive or Non-Reactive. Interpreting Syphilis Test Results A Non-Reactive result indicates that treponemal antibodies were not detected, which is consistent with no current or past syphilis infection. In very early primary syphilis within the first 1 to 2 weeks before the immune response has fully developed, the test may occasionally be negative. If clinical suspicion remains high with a genital ulcer or known exposure, repeat testing after 2 to 4 weeks is recommended. A Reactive treponemal test result confirms exposure to Treponema pallidum and indicates either active syphilis requiring treatment or successfully treated past syphilis. Unlike non-treponemal tests such as VDRL and RPR, treponemal antibodies persist lifelong after infection even after successful treatment, meaning a reactive result in a previously treated patient does not necessarily indicate active disease. Clinical staging, treatment history, and a quantitative non-treponemal test such as RPR are required alongside a reactive treponemal result to determine whether the infection is active and requires treatment or represents successfully treated past infection.

No fasting is required for the Syphilis test. You can eat and drink normally before sample collection. Our team confirms preparation requirements at the time of booking. Inform the phlebotomist about all medications you are currently taking, particularly immunosuppressants, as these can affect antibody levels and must be disclosed for accurate interpretation. Inform your doctor about any previous syphilis diagnosis and treatment history, as treponemal antibodies persist lifelong after infection and a reactive result in a previously treated patient requires clinical interpretation in the context of prior treatment. Inform your doctor if you are pregnant, as antenatal syphilis screening is a standard requirement and reactive results in pregnancy require immediate assessment for foetal risk and urgent treatment initiation. Stay normally hydrated before sample collection.

If you are booking through the SecondMedic platform the Syphilis test price starts at approximately Rs. 231. The exact price will be confirmed at the time of booking through SecondMedic. If your doctor has prescribed multiple tests alongside Syphilis, SecondMedic health packages include Syphilis as part of a broader sexually transmitted infection screening or antenatal panel at a significantly lower combined price.

SecondMedic provides home sample collection for Syphilis test across all major areas in India. You do not need to visit a lab or collection centre. A certified and trained phlebotomist comes to your home or workplace at your chosen time, collects the sample using sterile single-use equipment, and ensures it is transported to the NABL-accredited lab within the required time window for accurate processing. Please note that SecondMedic provides free home sample collection on all tests priced above Rs. 300. Our team will check your pincode and confirm if your address falls under our free sample collection eligibility criteria, which depends upon the lab location and phlebotomist availability. Home collection is available between 7 AM and 10 PM, seven days a week, including Sundays and public holidays. Enter your pincode on the booking page or call our helpline to confirm availability at your address.
