About this test

HIV is a virus that weakens the immune system. CDC recommends that everyone aged 13 to 64 get tested at least once, and that some people test at least once a year, including men who have sex with men and people with more than one partner.

There are three kinds of HIV test. Antigen/antibody tests look for antibodies and for a piece of the virus called an antigen. The lab version uses blood from a vein, and rapid versions use a finger stick. Antibody tests look only for antibodies. CDC says most rapid tests and FDA-approved self-tests are antibody tests, and they can use blood or oral fluid. Nucleic acid tests, or NATs, look for the virus itself and detect it earliest.

A positive antibody or self-test result needs a follow-up test to confirm it. HIV is reportable by name in every state, and reports are kept confidential. If you test positive, CDC says to start treatment as soon as possible. Treatment that keeps the virus undetectable means you will not pass HIV on through sex.

When to test

The window depends on the test type. CDC says a nucleic acid test (NAT) can usually detect HIV 10 to 33 days after exposure. A lab antigen/antibody test on blood from a vein can usually detect it 18 to 45 days after exposure. A rapid antigen/antibody test from a finger stick takes 18 to 90 days, and an antibody test, including most rapid tests and self-tests, takes 23 to 90 days. A negative result after the window for your test type, with no new exposure in that time, means you don't have HIV. If the exposure was in the last 72 hours, ask about PEP now. CDC says it must start within 72 hours.

Retesting

If you tested during the window period, test again once it has passed for your test type. After a possible exposure, CDC's sexual assault guidance repeats HIV tests at 6 weeks and 3 months. CDC says people at ongoing risk should test at least once a year, and sexually active gay and bisexual men may benefit from testing every 3 to 6 months.

Reported to public health

Positive results for this infection are reported to the state or local health department, which keeps them confidential. That includes tests you order online. What that means for your privacy

Common questions

Can I test for HIV at home?

Yes, in two ways. A home collection kit sends your sample to a lab. An HIV self-test gives a result at home, and CDC says you can get results within 20 minutes. Most self-tests are antibody tests, so they can take up to 90 days after exposure to turn positive, and a positive result needs a follow-up test.

How soon after sex can I test for HIV?

It depends on the test. A lab antigen/antibody test on blood from a vein can usually detect HIV 18 to 45 days after exposure. A NAT can detect it 10 to 33 days after. Rapid and antibody tests can take up to 90 days.

What is PEP, and when do I need it?

PEP is medicine that can prevent HIV after a possible exposure. CDC says it must be started within 72 hours. If your exposure was that recent, go to an urgent care, emergency room or your doctor now. Testing can wait.

Will a positive HIV result be reported?

Yes. CDC says all states use name-based HIV reporting to the state or local health department, and the reports are confidential. The data passed on to CDC don't include personal identifiers.

Which HIV test is in an STD panel?

It varies. Check whether a panel uses a lab antigen/antibody test, an antibody test or a NAT, because the window period is different for each. The What's included column and the provider page usually name the test.
