Question

Quizplus · Accepted Answer

ELISA test for antibody and Western blot are not reliable in detecting HIV infection in infants younger than 18 months of age because infants born to HIV-infected mothers carry their mother's antibodies for several months, which may give false-positive test results. P24 antigen testing is more reliable than antibody testing in detecting early HIV infection, but it may not detect all cases of HIV infection in infants. DNA PCR testing, which detects the presence of HIV DNA in an infant's blood, is the most reliable test for diagnosing HIV infection in infants younger than 18 months of age, as it is not affected by the presence of maternal antibodies.
