No HIV test can detect HIV immediately after infection. That's because of the window period—the time between HIV exposure and when a test can detect HIV in your body. The window period depends on the type of HIV test. A nucleic acid test can usually detect HIV the soonest (about 10 to 33 days after exposure). Learn more about the window period for each HIV test. If you think you've been exposed to HIV in the last 72 hours, talk to a health care provider, an emergency room doctor, or an urgent care provider about post-exposure prophylaxis (PEP) right away.

HIV Testing: Types, How Often, What To Expect & Results
Oct 25, 2022 — How soon after exposure to HIV can a test detect the virus? ... A nucleic acid (NAT) test has the shortest window period. It can tell if you have an HIV infection from 10 to 33 days after exposure. Antigen/Antibody tests can detect infection from 18 to 45 days after exposure (for blood draw tests) or 18 to 90 days after exposure (for finger-prick tests). Antibody tests (most rapid and at-home tests) can detect infection 23 to 90 days after exposure.
The window period for tests done with finger prick blood or oral fluid is likely to be longer. Additionally, taking pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis
(PEP) may extend the window period because of a delayed antibody response.

If you've been tested once within the window period, you'll need to wait until the end of the period to have a second test to confirm your result. For example, if you had a potential exposure on January 1, your 3-month window period would be up to March 31. If you test at any point during that period and the result is negative, there is still the possibility that HIV was not picked up by the test.

Early HIV symptoms most often appear 2–4 weeks after a person catches the virus. The symptoms can seem like a bad case of the flu and often include fever and chills.

The window period
for HIV tests depends on the type of test. A nucleic acid test
(NAT) can usually detect HIV 10–33 days after exposure, while an antigen
/antibody test can detect HIV 18–45 days after exposure, and a rapid antigen/antibody test can detect HIV 18–90 days after exposure. Antibody tests, which are the most common type of rapid test and at-home test, can detect HIV 23–90 days after exposure.

Jun 22, 2022 — A rapid antigen/antibody test done with blood from a finger stick can usually detect HIV 18 to 90 days after exposure. An antigen/antibody lab test using blood from a vein can usually detect HIV 18 to 45 days after exposure. A nucleic acid test (NAT) can usually detect HIV 10 to 33 days after exposure.

HIV Testing Overview
Types of HIV Tests and Their Window Periods ... Antigen/Antibody Test—An antigen/antibody test performed by a laboratory on blood from your vein can usually detect HIV infection 18 to 45 days after exposure. An antigen/antibody test done with blood from a finger prick takes longer to detect HIV (18 to 90 days after an exposure). Antibody Test—An antibody test can usually detect HIV infection 23 to 90 days after an exposure. Most rapid tests and self-tests are antibody tests. In general, antibody tests that use blood from a vein detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid.

The results have been reduced greatly with tests such as orasure .
Now when I was diagnosed in 1989 the test results took at least a week to be determined altho since the arrival of orasure and other tests discovery time can take as little as 15 minutes .

@A myHIVteam Member. No. Although the course of HIV disease is long. The body will produce antibodies in less than 3 months.
