How long after unprotected sex does the P24 antigen become detectable on a HIV test? When it comes to HIV testing, two of the most common questions we are asked online or in person are: “When can I test for HIV?” and “Are my results conclusive?” There is a lot of confusing information out there, so this article will try to break down the timelines for accurate testing, and why this is the case. It is useful because the p24 antigen rises soon after infection and sooner than antibodies. As a result, an antigen/antibody test can detect the virus before an antibody test can. Therefore, to enable the laboratory to select appropriate testing, it is important to provide a clinical history that includes any recent high-risk behaviour or symptoms consistent with seroconversion illness ( 1 - 3 ). 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). The p-24 antigen tests will often show positive 2-3 weeks after initial infection. The test is often used with an antibody test to cover a longer period of time - known as the window period - when infection may have occurred.

In a small number of early seroconverters who are still in the 'window period', the p24 antigen may become positive before antibody is detectable.
