Laboratory Diagnosis of HIV Infection

Diagnostic HIV Testing in Infants

October 2009

Therefore, HIV infection can be reasonably excluded if there are more than 2 negative HIV-virologic tests, preferably taken at 1 month or more in the individual newborn and again at 4 months after birth. Alternatively, if molecular tests or virologic tests are not available, then 2 negative HIV-serologic tests, at more than 6 months after age, is also possible to exclude HIV infection in such infants born to HIV-infected mothers.
