The HIV 1 & 2 Abs/p24Ag test is a diagnostic test used to detect both HIV antibodies (Abs) and the p24 antigen (Ag) in blood samples. The test is important because it provides a comprehensive and early method for detecting HIV infection. It combines the detection of antibodies and the p24 antigen, allowing for early diagnosis, which is crucial for effective treatment and prevention of transmission. The test plays a significant role in public health by ensuring safe blood supplies, supporting maternal health, and contributing to the reduction of HIV stigma and the overall control of the HIV epidemic.
