About HIV 1 & 2 Ab & p24 Ag (Combo) Test
HIV 1 and 2 antibodies & p24 Antigen test detect the presence of both human immunodeficiency virus (HIV) antibodies and p24 antigen (protein) present on the surface of HIV virus-infected cells in your blood. HIV is a sexually transmitted infection (STI) that attacks and destroys immune cells that protect your body against diseases. Symptoms usually appear 2–4 weeks after infection, but they can take months (the window period) to appear. Sometimes, HIV infection can result in life-threatening acquired immunodeficiency syndrome (AIDS).
An HIV 1 & 2 Ab & p24 Ag test helps you know if you have an infection, and with early detection, you can receive early treatment. The available treatment for HIV can help strengthen the immune system and fight the virus more effectively. Thus, receiving early treatment can prevent the progression of AIDS

Interpretation of results
Positive test result
If you have a positive result for HIV 1 & 2 Ab & p24 Ag test, it means that HIV viruses were found in your sample. A follow-up test is required to confirm the HIV diagnosis.

Negative test result
A negative result for HIV 1 & 2 Ab & p24 Ag test, suggests that no HIV viruses were found in your sample. However, this doesn’t necessarily mean that you don’t have HIV.

After the window period, if the test result is negative, provided you have no other exposure during that time, it means that you do not have an HIV infection. Negative test results may require further testing after 4 weeks.
