Additional Information / Important Notes
Repeatedly reactive specimens must be investigated using supplemental tests for HIV-1 and/or HIV-2 and/or p24 antigen. In specimens giving indeterminante supplemental test results, testing of a subsequent sample drawn at a later date is recommended.
For individuals who are confirmed positive for antibodies and/or p24 antigen, appropriate counsling and medical evaluation should be offered.
