- The p24 antigen test can detect the p24 protein on average 10 to 14 days after infection with HIV. , , , One drawback of this test is that levels of the p24 protein peak at around three to four weeks after exposure to HIV and are usually not detectable after five to six weeks (and sometimes even earlier).

HIV Screening: Tests That Diagnose HIV The CDC recommends these blood tests. They can detect HIV as soon as 20 days earlier than antibody screening tests. They check for HIV antigen, a protein called p24 that's part of the virus that shows up 2-4 weeks after infection, as well as HIV antibodies. A rapid antibody/antigen test can give you results in 20 minutes. RNA Test. This looks for the virus itself and can diagnose HIV about 10 days after you've been exposed. It's expensive, though, so it's usually not the first test.

HIV/AIDS These antigen/antibody combination tests can find HIV as soon as 3 weeks after exposure to the virus, but they are only available for testing blood, not oral fluid. The rapid test is an immunoassay used for screening, and it produces quick results, in 30 minutes or less.or antibody tests, if you get a negative result within 3 months of your most recent possible exposure, you need to get tested again at the 3-month mark. For RNA tests or antibody/antigen tests, that timeframe may be shorter.

- There are different types of HIV Tests, and each type has a different window period. We have a more in depth article about HIV test window periods. A test taken at least 12 weeks (3 months) after exposure to the virus provides highly accurate results. In rare cases, a person could take up to six months to test positive using standard tests, and that is almost always a person with a severely compromised immune system due to another disease, such as leukemia.

Top 30 Doctor insights on: How Long Does Hiv Live On Surfaces The time period from infection with HIV until the body produces enough HIV antibodies to be detected by an HIV antibody test is called the window period. Most people develop HIV antibodies within 3 months after they are infected with HIV. But the window period can vary depending on the HIV test used. In general, anyone who has a negative result on an HIV antibody test within 3 months of a possible exposure to HIV should have the test repeated in 3 months.

How long do HIV test results take? How are they reported? How long do HIV test results take? How are they reported? How long do results take? Rapid HIV tests can give results in 15—60 minutes, or on the same day. ‘Rapid’ refers for the time taken for the results and not the time since exposure that a test can be used. If samples are being sent to another lab, results can take a few days or a few weeks. Rapid blood tests put a pin-prick of blood on a testing strip. This test takes about 15-20 minutes so you can get the results whilst you wait. Some rapid tests also work on oral samples rather than blood. Although they are sometimes called saliva tests this is not accurate.

HIV Testing Antibody tests check for HIV antibodies in blood or fluids from the mouth. HIV antibodies are disease-fighting proteins that the body produces in response to HIV infection. It can take 3 to 12 weeks for a person’s body to make enough antibodies for an antibody test to detect HIV infection.

Diagnosis of HIV/AIDS The vast majority of people (97%) have detectable antibodies by three months after HIV infection; a six-month window is extremely rare with modern antibody testing. During the window period, an infected person can transmit HIV to others although their HIV infection may not be detectable with an antibody test.

HIV Testing Antibody tests detect the presence of antibodies, proteins that a person’s body makes against HIV, not HIV itself. Most HIV tests, including most rapid tests and home tests, are antibody tests. It can take 3 to 12 weeks for a person’s body to make enough antibodies for an antibody test to detect HIV infection. In general, antibody tests that use blood can detect HIV slightly sooner after infection than tests done with oral fluid.

- Other HIV tests have been developed, which detect the virus itself—such as the HIV RNA or the p24 antigen tests. These have shorter window periods (from seven to 14 days) than antibody tests and so can potentially detect HIV infection during the acute phase.he time period from when a person becomes infected with HIV to when an HIV test can detect their infection, is known as the “window period.” During the “window period,” an HIV test may find a recently infected person to be HIV-negative.

What Is HAART? The most commonly used HIV tests detect the presence of these antibodies. There are rapid tests that can provide results in 20 minutes 2, but it usually takes 6–8 weeks after someone has been exposed to the virus for enough HIV antibodies to accumulate for accurate detection through testing (although improved HIV tests are now reducing this window to 2 weeks).
