The STI Basic Panel covers the four most commonly screened sexually transmitted infections. It includes 4th-generation HIV testing (antigen + antibody), Chlamydia and Gonorrhea (urine-based RNA detection), and Syphilis screening. The CDC recommends STI screening for all sexually active adults, especially those with new partners or multiple partners.
3-test STI screen: HIV (4th-gen), Syphilis (with confirmation), Hepatitis C. The lowest-cost option for routine STI screening when partner-monitoring or post-exposure peace of mind is the goal.
Sexually active adults wanting routine screening, anyone with new partners, before a relationship status change. Add the [STI Comprehensive Panel](/tests/sti-comprehensive-panel) if you want chlamydia/gonorrhea and hepatitis B coverage.

An STI Basic Panel costs $84.99 at TestWell — $90.99 all-in, since the $6 lab processing fee is charged once per order and there is no draw or physician fee. The labs' own sites list the closest equivalent at $149.00 at Quest Health and $189.00 at Labcorp OnDemand (checked Oct 21, 2026; see the product notes). With insurance you pay your plan's negotiated rate against your deductible; TestWell's price is fixed before the draw and HSA/FSA-eligible.

Basic: HIV, Syphilis, Hepatitis C — 3 tests, $84.99. Comprehensive: adds chlamydia/gonorrhea, hepatitis B, and herpes — 6 tests, $249.99. Basic is the screening starter; Comprehensive is the complete workup.
HIV (4th-gen): test at 2-4 weeks, retest at 6 weeks and 3 months. Syphilis: 3-6 weeks after exposure. Hep C: 8-12 weeks after exposure. If exposure was within 72 hours, see urgent care immediately for HIV PEP (post-exposure prophylaxis) — it can prevent infection if started early.
On TestWell, the STI Basic Panel is $84.99. Ordering the same 3 tests separately would be about $110. Quest Health lists comparable bundles at $125, walk-in hospital labs typically bill $300-450 for the same biomarkers without insurance. Free testing is also available at most community health centers and Planned Parenthood.
Your TestWell order is private — only you can see your results in your account. Positive results that require reporting to public health (HIV, syphilis) are reported by the lab per state law, not by TestWell. We don't share your data with insurance or employers.
All TestWell STI tests use confirmatory algorithms — a reactive screen automatically triggers confirmation testing before reporting positive. You'll get follow-up instructions and provider resources with any positive result. Most STIs are highly treatable — HIV is now a chronic manageable condition, syphilis is cured with antibiotics, Hep C is curable in 95%+ with 8-12 weeks of pills.
Annually for sexually active adults with stable partners. Every 3-6 months for MSM, anyone with multiple partners, or anyone using PrEP. After any new partner. After unprotected exposure with unknown-status partner.
STI Basic Panel results are typically ready in 2–5 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
No, fasting is not required for an STI Basic Panel — you can eat normally and book any time of day. Do not urinate for at least 1 hour before providing urine sample. No fasting required.
