You can get an HIV test kit at most major pharmacies, online retailers like Amazon, or for free through government programs. Over-the-counter kits typically cost around $30 to $40, and results take anywhere from one minute to several days depending on the type of test you choose.
Pharmacies and Online Retailers
HIV self-test kits are sold without a prescription at chain pharmacies like CVS, Walgreens, and Walmart, as well as through Amazon and other online retailers. The most widely available option, the OraQuick self-test, currently sells for about $33 to $40 online. You can walk into a pharmacy and buy one off the shelf, or order one delivered to your home if you prefer more privacy.
A newer option, the INSTI HIV Self Test, uses a fingerstick blood sample instead of an oral swab. It received FDA approval for over-the-counter use and is also available at major retailers and online, though it may be harder to find in physical stores depending on your area.
How to Get a Free Kit
The CDC runs a program called Together Take Me Home that mails free HIV self-test kits directly to you, subject to availability. You order through their website, and the kit arrives in discreet packaging. Many local health departments and HIV service organizations also distribute free or low-cost self-tests. A quick search on HIV.gov or a call to your local health department can point you to what’s available near you.
If you have health insurance, HIV screening is covered without cost-sharing under the Affordable Care Act for anyone aged 15 to 65, and for younger or older people at increased risk. This applies to most private insurance plans, Medicare, and Medicaid. That coverage typically applies to tests performed at a clinic or lab rather than over-the-counter kits, so if cost is a concern, getting tested at a healthcare facility or community health center may be your cheapest route.
Types of Self-Test Kits
There are two main approaches to at-home HIV testing: rapid self-tests and mail-in blood sample kits.
- Rapid oral swab (OraQuick): You swab your gums and place the swab in a vial of testing solution. Results appear in about 20 minutes. No blood draw required, which makes it the simplest option.
- Rapid fingerstick (INSTI): You prick your finger, apply a drop of blood to the test device, and get results in about one minute. It tests for both HIV-1 and HIV-2 antibodies.
- Mail-in blood sample: You collect a small blood sample at home using a dried blood spot card, then mail it to a lab. Results come back in a few days. Some users find these kits trickier to use. In one study, about a third of participants in a mail-in testing group reported problems with confusing directions, difficulty collecting enough blood, or trouble with shipping.
The rapid options are better if you want answers quickly and with minimal hassle. Mail-in kits may offer slightly different testing technology, but the convenience trade-off is real.
Accuracy and the Window Period
All at-home HIV tests detect antibodies your immune system produces in response to the virus. They do not detect the virus itself. This matters because your body needs time to produce enough antibodies for a test to pick up. For the OraQuick oral test, that window period is about three months. If you were potentially exposed to HIV less than three months ago, a negative result may not be reliable, and you’d need to test again after the window closes.
The OraQuick test correctly identifies about 92% of people who have HIV (sensitivity) and 99.98% of people who don’t (specificity). That high specificity means false positives are extremely rare. The 92% sensitivity means the test misses roughly 1 in 12 positive cases, mostly due to testing during the window period. If you test negative but believe you were recently exposed, testing again after three months gives you a much more definitive answer.
What Happens After a Positive Result
A positive result on any at-home antibody test is preliminary, not a diagnosis. You need a follow-up confirmatory test from a healthcare provider or lab. If you take a self-test at home and it comes back positive, go to a healthcare provider or community testing site for that second test. If the confirmatory test is also positive, that confirms HIV infection.
This two-step process exists because no screening test is perfect, and the consequences of a false positive are significant enough to warrant verification. Most community health centers and local health departments can perform confirmatory testing, often at no cost. The follow-up test typically uses a different method, such as a lab-based blood draw that can detect the virus more directly, giving you a definitive answer.
