Explanation:

The definitive diagnosis of HIV infection at any age requires diagnostic testing that confirms the presence of HIV. Serological testing identifies HIV antigen and/or antibody generated as part of the immune response to infection with HIV. In children older than 18 months of age, serological testing should be used in the same manner as in adults. However, maternal HIV antibody is transferred to the baby passively during pregnancy and then declines (with a half-life of 28–30 days in non-breastfed infants) (24-29). Infected infants then go on to produce HIV antibody (30); however, most commonly used HIV serological assays cannot distinguish between maternal HIV antibody and HIV antibody produced by the infant, making the interpretation of reactive HIV serological test results difficult (29, 31). In order to diagnose HIV infection definitely in children aged less than 18 months, assays are required that detect the virus or its components
