# HIV p24 Antigen/Antibody With Reflex to Confirmation

> This test measures both the antibodies your immune system creates to fight the Human Immunodeficiency Virus (HIV) and a specific viral protein called the p24 antigen. Because the antigen appears in the blood sooner than antibodies, this test helps detect HIV infection at an early stage.
