Is HIV p24 Ag +IgG test result conclusive at 115th day or so?

 HIV testing guidelines generally recommend retesting at least 90 days (around 3 months) after potential exposure for conclusive results, as this is the period it typically takes for detectable levels of HIV antibodies to develop in the bloodstream. However, different testing methods have varying windows of detection.



The p24 antigen test detects the presence of a protein called p24, which is part of the HIV virus itself. This test is generally reliable within the first few weeks after infection, as p24 antigen levels tend to peak during this early stage. However, it may not be as sensitive or reliable in later stages of infection.

The HIV IgG antibody test detects antibodies produced by the body in response to HIV infection. Antibodies typically become detectable within 2 to 8 weeks after infection, but in some cases, it may take up to 3 months.

Combining both the p24 antigen test and the HIV IgG antibody test increases the likelihood of detecting HIV infection earlier and improving the accuracy of the test results.

Given your mention of a p24 Ag + IgG test result at 115 days post-exposure, it's highly likely that the result is conclusive. However, it's always best to consult with a healthcare professional for personalized advice and interpretation of test results. They can provide the most accurate information based on your specific situation and any additional risk factors you may have.
