Quest and Labcorp STD Testing: How to Get Tested at a Lab
Quick answer
Yes. Both Quest and Labcorp sell STD tests directly online. You buy the test, give a urine or blood sample at one of their locations (Labcorp also lists at-home collection kits), and get results online. Quest says no doctor visit is required to buy, while Labcorp OnDemand says all of its testing requires an order from an authorized healthcare professional. Quest says it does not bill insurance. Prices are listed on each site and change, so check them at checkout.
The test you need
- Test
- Basic STD panel (chlamydia, gonorrhea, syphilis, HIV-1 and HIV-2), as Quest lists it
- Sample
- Blood and urine, or a patient-collected vaginal swab (Quest basic panel)
- When
- Depends on the infection and test. The CDC's HIV windows run from 10 to 90 days after exposure depending on test type.
- Results
- Quest emails a secure link when results are ready; in some states delivery may be delayed by a few days. Labcorp says results come through its online portal.
Is a Quest or Labcorp order a good fit?
If you want a throat or rectal swab, a pelvic exam or treatment at the same visit, a clinic is a better fit. This is a guide to choosing a route, not medical advice.
Quest and Labcorp are two of the biggest names in US lab testing, and both now let you buy STD tests without going through a clinic first. Here is how that works, what each lists, and where the limits are.
Does Quest do STD testing?
Yes. Quest Health’s STD page says you can buy your own STD tests online, that no doctor visit is required for purchase, and that you complete sample collection at one of 2000+ nearby locations. Results are delivered online. You also get the ability to discuss results with an independent healthcare provider.
For its basic panel, Quest lists chlamydia, gonorrhea, syphilis, HIV-1 and HIV-2, with a blood and urine sample or a patient-collected vaginal swab. You schedule an appointment, then visit a Quest patient service center, and it says same-day appointments are often available.
Fine print from Quest’s basic panel page:
- You must be 18 or older to buy.
- Collection is not available in AZ, HI or PR.
- Quest does not bill insurance, and purchases cannot be submitted for insurance reimbursement.
- A $6 physician service fee is added.
Does Labcorp do STD testing?
Yes. Labcorp OnDemand lets you buy tests on its site, and says results can be accessed through your Labcorp Patient account. It says all testing requires an order from an authorized healthcare professional, and that you visit a Labcorp location for sample collection or use an at-home collection kit. It says testing is performed in a CLIA-certified clinical laboratory, and that results come through a secure online portal.

Use these as a rough guide only. See STD test cost for what drives price.
Can I use insurance at Quest or Labcorp?
Quest says it does not bill insurance for these tests. Labcorp’s STI page does not address insurance, so check its checkout and help pages.
If you want your plan to pay, the route is different: your own clinician orders the tests, and you use an in-network lab. Healthcare.gov says preventive screenings such as HIV and syphilis screening for adults at higher risk are generally covered at no cost from an in-network provider, and that $0 is not guaranteed in all cases.
How do online STD services use Quest and Labcorp?
Some online services route you to these labs or to others. STDCheck, our test link partner, says on its About page that it uses CLIA-certified labs like Quest Diagnostics and LabCorp. Its testing pages refer to 4,500 testing centers without naming them, so check which lab you will be sent to before buying. It says most results arrive in 1 to 2 business days, that you need no appointment, and that it does not accept insurance.
Walgreens says its Virtual Healthcare STI testing can be performed at a Labcorp or Quest Diagnostics location, with a separate lab fee. See online STD testing for how these services compare.
What are the limits of a lab order?
- Sample types. Quest’s basic panel lists blood and urine or a vaginal swab. If you need a throat or rectal swab, the CDC’s guidance is to test the sites of exposure, so ask a clinic about those.
- Timing. A lab test is only as reliable as its timing. The CDC’s HIV windows run from 10 to 90 days depending on the test type. The window-period calculator can help you pick a date.
- Follow-up. Quest says the provider call cannot directly provide HIV or syphilis treatment. If a result is positive, contact a clinician.
What if I may have been exposed to HIV in the last 72 hours?
A lab appointment is not the right first step. HIV.gov says PEP must be started within 72 hours or it won’t work, and says to contact a health care provider immediately or go to an emergency room or urgent care clinic right away. Test afterward.
Get care now if
- You may have been exposed to HIV in the last 72 hours: go to an emergency room or urgent care clinic right away and ask about PEP
- You have severe pain in your belly, pelvis or testicles, or a fever with genital symptoms: get care today instead of booking a lab
- You are pregnant and think you may have been exposed: tell your prenatal clinician now
Call 911 for a medical emergency. Otherwise, an urgent care clinic, sexual health clinic or your doctor can see you.
When to test
- If a possible HIV exposure was in the last 72 hoursDo not wait for a lab appointment. Go to an emergency room or urgent care clinic right away and ask about PEP.
- After the window period for the infectionA lab test can miss a recent infection. For HIV the CDC says nucleic acid tests can usually detect HIV 10 to 33 days after exposure, lab antigen/antibody tests 18 to 45 days, and antibody tests 23 to 90 days. Use the window-period calculator for other infections.
- After a positive resultTalk to a clinician about next steps. Quest says its included provider call cannot directly provide HIV or syphilis treatment.
Common questions
Do I need a doctor to order a Quest or Labcorp STD test?
Quest says no doctor visit is required to buy its STD tests. Labcorp OnDemand says all of its testing requires an order from an authorized healthcare professional. Read each site's checkout steps to see how that order is handled.
Can I use insurance?
Quest says it does not bill insurance and that purchases cannot be submitted for insurance reimbursement, though HSA or FSA funds may be accepted. Labcorp's STI page does not say. If you want your plan to be billed, ask your own clinician to order the tests and check that the lab is in your network.
How long do results take?
Quest says you get a secure link by email when results are ready, and that in some states delivery may be delayed by a few days. Labcorp says results come through its online portal and gives no timeframe on its STI page. Ask about timing when you book.
Are the labs the same ones online services use?
Sometimes. STDCheck's About page says it uses CLIA-certified labs 'like Quest Diagnostics and LabCorp', though its testing pages do not name the labs. Walgreens says its Virtual Healthcare STI testing can be done at a Labcorp or Quest location.
Next: Basic STD panel (chlamydia, gonorrhea, syphilis, HIV-1 and HIV-2), as Quest lists it.
Blood and urine, or a patient-collected vaginal swab (Quest basic panel). Depends on the infection and test. The CDC's HIV windows run from 10 to 90 days after exposure depending on test type.
