HIV testing is a process used to detect the presence of the human immunodeficiency virus (HIV) in the body. It involves analyzing a blood sample or oral fluid sample to look for antibodies, antigens, or genetic material related to the virus. The most common types of HIV tests include antibody tests, antigen tests, and nucleic acid tests (NATs). These tests are important for diagnosing HIV infection, monitoring the progression of the disease, and determining the effectiveness of treatment. It is crucial to get tested if you believe you may have been exposed to HIV.
