HIV self-tests give results within 20 minutes, and rapid tests at a clinic or community site take 30 minutes or less. Lab tests, including antigen/antibody blood draws and nucleic acid tests (NATs), can take several days. How fast a result comes back is separate from how soon a test can detect HIV. A reactive rapid test or self-test always needs a follow-up test to confirm it.[1][2]

Result time, test by test

CDC and HIV.gov publish these usual times for getting a result:[1][2]

With a rapid test at a clinic or testing site, you can often wait there for your result.[2] For a lab test, ask the clinic when results usually come back and how they will contact you. Times vary by clinic and lab.

A fast result is not the same as an early result

No HIV test can detect HIV right after an exposure. The time before a test can detect it is called the window period, and it depends on the test, not on how fast the result comes back.[1]

So lab tests take longer to return a result but can detect HIV sooner after an exposure. If you test negative inside the window for your test, CDC advises testing again after that window has passed.[1] Our window period guide explains each test in detail.

If your result is reactive

A reactive (positive) result on an antibody test needs a follow-up test to confirm it. If you used a self-test or tested at a community program, CDC says to see a health care provider for follow-up testing. If the follow-up test is also positive, it means you have HIV.[1][2]

A confirmed result is the start of care, not the end of the road. HIV treatment lets people living with HIV live long, healthy lives, and people who reach and keep an undetectable viral load do not transmit HIV through sex. Read what to do after testing positive for next steps.

While you wait

If your possible exposure was in the last 72 hours, do not wait for any test result. Ask a clinic, urgent care or emergency room about PEP right away. PEP must be started within 72 hours, and every hour counts.[3]

Waiting can be stressful. If it feels like too much, you can call or text 988 at any time to talk with someone.

Florida: free tests and results at home

Florida residents can request a free at-home OraQuick test through KnowYourHIVStatus.com, which gives a result in about 20 minutes. It is an antibody test, so an early negative cannot rule out a recent exposure. Florida also lists more than 1,600 publicly funded and registered testing sites. Use our care locator to find one near you.[4][5][1]

Related questions

How long does a rapid HIV test take?

A rapid test at a clinic or community site gives a result in 30 minutes or less. An HIV self-test at home gives a result within 20 minutes.[1][2]

Why do lab HIV test results take several days?

Lab tests send your blood sample to a laboratory for processing. CDC says results from a lab antigen/antibody test or a NAT may take several days. In return, these tests can detect HIV sooner after an exposure than rapid tests.[1]

Is a fast negative result accurate?

A negative result is reliable only if you tested after the window period for that test and had no new exposures since. If you tested inside the window, test again once it has passed.[1]

Does a reactive rapid test mean I have HIV?

Not on its own. A reactive antibody test, including a self-test, needs a follow-up test from a health care provider to confirm it. If the follow-up test is also positive, it means you have HIV.[1][2]
