One recommended strategy is to get tested 2-4 weeks, 3 months, and 6 months after a risky exposure. Using a sensitive antigen/antibody HIV test, of those who are infected, most will test positive at 1 month; almost all will test positive at 3 months; and the rest will test positive at 6 months.

Most infants born to HIV-positive women in the United States do NOT become HIV positive if the mother and infant have good prenatal and postpartum care. Infants who are infected with HIV often have no symptoms for the first 2 to 3 months. Once symptoms develop, they can vary.

Your doctor may be able to tell right away if you have an STD. But some tests take a few days or weeks to come back from a lab. Many clinics can do rapid testing for HIV — you'll get your result in about 20 minutes.

The body can take up to three months to produce these antibodies. Most people will have enough antibodies to test positive within three to 12 weeks after contracting HIV. At 12 weeks, or three months, 97 percent of people have enough antibodies for an accurate test result.

It usually takes a few days to a few weeks to get results of an HIV test, although rapid HIV tests can produce results in about 20 minutes.

You're having unprotected sex. Here's how long after exposure we can get a reliable test result: 2 weeks: gonorrhea and chlamydia (and a pregnancy test too!) 1 week to 3 months: syphilis. 6 weeks to 3 months: HIV, hepatitis C and B.

Rapid HIV tests can give results in 15 to 60 minutes, or on the same day. 'Rapid' refers to the time taken for the results and not to the time between exposure and the test. If samples are being sent to another lab, results can take from a few days or a few weeks.

Current tests typically become positive within 3–6 weeks of infection and 1–3 weeks after the onset of acute HIV symptoms [1]. While detection of early infection is a strength of these tests, it creates challenges in identifying persons with very early HIV.

Viral load and p24 tests are not accurate for diagnosing early HIV if the results are negative. An HIV antibody response can be detected as early as two weeks in a few people and in more than 99.9% of people by 12 weeks. An antibody test at 4 weeks will detect 95% of infections.

When the virus enters your body, your immune system makes proteins called antibodies. It takes time for the body to develop HIV antibodies after infection. Almost all persons develop antibodies within 2 to 12 weeks, but it can take up to 6 months after infection.

Within 2 to 4 weeks after infection with HIV, about two-thirds of people will have a flu-like illness. This is the body's natural response to HIV infection.

It depends. It can take 3 months for HIV to show up on a test, but it only takes a matter of days to a few weeks for STDs like gonorrhea, chlamydia, and syphilis to show up. Practicing safer sex lowers your chances of getting or spreading STDs.

At this early stage of HIV infection, it's important to know that you may not get accurate results from an HIV test. It can take 3-12 weeks for enough signs of the virus to show up on routine tests for the infection, which measure antibodies against HIV.

These signs and symptoms of acute HIV infection can begin a few days after you are exposed to HIV and usually last for about 14 days. They could last for just a few days, or they could last for several months. You might not realize your illness is acute HIV infection.

HIV RNA test ("viral load") is positive in patients with acute HIV infection. Lower-than-normal CD4 (white blood cell) count may be a sign of a suppressed immune system. The CD4 count usually improves 1 - 2 months after acute infection.

If you've had or want to start having sex — vaginal, anal, or oral — with a new partner, without a condom, it's a good idea to get tested. Here's how long after exposure we can get a reliable test result: 2 weeks: gonorrhea and chlamydia (and a pregnancy test too!)
