Diagnosing HIV in infants and young children can be challenging due to the presence of maternal antibodies. The following tests are commonly used: 1. HIV DNA PCR test: This is the preferred test for diagnosing infants under 18 months. 2. HIV RNA test: This test detects the virus's genetic material. 3. HIV antibody test: This test is used for children older than 18 months.
Early diagnosis is critical for initiating treatment and improving outcomes.
