The HIV p24 + IgG test is a blood test used to detect antibodies against HIV (Human Immunodeficiency Virus) in the blood, specifically targeting the p24 antigen and IgG antibodies. The p24 antigen is a protein present in the HIV virus, and IgG antibodies are produced by the immune system in response to HIV infection.
This test is often used for HIV screening and diagnosis. It can detect HIV infection as early as two to four weeks after infection, as the p24 antigen appears in the blood during the early stages of HIV infection, followed by the production of IgG antibodies.
Regarding the timing of the test, it is generally recommended to wait at least 90 days (three months) after potential exposure to HIV before taking this test. This waiting period allows for the body to produce detectable levels of antibodies, ensuring the test's accuracy. Testing too early after exposure may result in a false negative result due to insufficient antibody levels.
In summary, yes, the HIV p24 + IgG test can be taken after the 90th day following potential exposure to HIV for accurate results. However, it's always best to consult with a healthcare professional for personalized advice and testing recommendations based on individual circumstances.
