Presumptive

Based on a reasonable assumption. In non-breastfed infants born to mothers with HIV, presumptive exclusion of HIV infection is based on two or more negative virologic tests, one at age 14 days or older and the other at age 1 month or older; or one negative virologic test at age 8 weeks or older; or one negative HIV antibody test at age 6 months or older. Additional testing is necessary to definitively exclude HIV infection.
