It can take up to three to 12 weeks for your body to make enough antibodies for an antibody test to detect HIV infection. 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.

A human immunodeficiency virus (HIV) test detects HIV antibodies or antigens, or the genetic material (DNA or RNA) of HIV in blood or another type of sample. This determines whether an HIV infection is present (HIV-positive). ELISA results are usually available in 2 to 4 days.

An antigen/antibody test performed by a laboratory on blood from a vein can usually detect HIV infection 18 to 45 days after an exposure. There is also a rapid antigen/antibody test available that is done with a finger prick.

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.

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.

In some cases, urine and blood tests aren't as accurate as other forms of testing. It may also take a month or longer after being exposed to certain STIs for blood tests to be reliable. If HIV is contracted, for example, it can take a couple of weeks to a few months for tests to detect the infection.

Yes. Modern HIV tests are very accurate. A confirmatory test three months after the exposure is always recommended. This is because 5% of people take this long to show a positive result. A positive test result is routinely confirmed using a different type of test called western blot.

Most people develop detectable antibodies within 6 weeks of infection; 97% respond within 3 months (1). Conservatively speaking, a result obtained today is only a reliable indicator of one's HIV status 3 months ago (the so-called “window period”).

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.

How soon after exposure to the hepatitis C virus can a test tell if someone is infected? After exposure to the hepatitis C virus, it can take 8–11 weeks for an HCV antibody test to be positive. For most people who are infected, the anti-HCV blood test will become positive by 6 months after exposure.

The symptoms usually last 1-2 weeks, but can be longer. They're a sign that your immune system is putting up a fight against the virus. But having these symptoms doesn't necessarily mean you have the HIV virus.

Other tests need to be sent to an external laboratory. The results will usually take between one to 14 days to come back.

If you test negative Talk with your healthcare provider about your test result and the type of test you took to understand what your result means. You could still have a current infection. The test may be negative because it typically takes 1–3 weeks after infection for your body to make antibodies.
1209607
Almost all persons develop antibodies within 2 to 12 weeks, but it can take up to 6 months after infection. A positive result means antibodies to HIV were found in your body. This means you have HIV infection. You are infected for life and can spread HIV to others.
673315
Most people experience a short flu-like illness 2 to 6 weeks after HIV infection, which lasts for a week or 2. After these symptoms disappear, HIV may not cause any symptoms for many years, although the virus continues to damage your immune system. This means many people with HIV do not know they're infected.

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.
263031
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.
