What is P24 tests?

P24 tests, also known as p24 antigen tests, are diagnostic tests used to detect the presence of the p24 protein, a component of the HIV virus, in the blood. They are particularly useful in the early detection of HIV infection, often before antibodies develop, making them valuable for diagnosing acute HIV. These tests can provide results more quickly than antibody tests, typically within a few hours to a day. However, they are usually used in conjunction with other tests to confirm an HIV diagnosis.
