Diagnosis

Blood tests are the most common way to diagnose HIV. These tests look for antibodies to the virus that the body creates in an attempt to fight the virus. People exposed to the virus should get tested immediately, although it can take the body anywhere from six weeks to a year to develop antibodies to the virus. Follow-up tests may be needed depending on the initial time of exposure.

Early testing is crucial. If you test positive for the virus, you and your doctor will discuss and develop a treatment plan that can help fight HIV and ward off complications. Early testing also can alert you to avoid high-risk behavior that can spread the virus to others.

Most health care providers offer HIV testing, often with appropriate counseling. Anonymous and free testing also is available. During testing, your doctor will ask about your symptoms, medical history and risk factors, and perform a physical examination.
