|HIV-1/2 Ab Screen, EIA||Non-Reactive|
A Non-reactive HIV-1/2 antibody result does not exclude HIV infection since the time frame for seroconversion is variable. If acute HIV infection is suspected, antibody retesting and nucleic acid amplification (HIV DNA/RNA) testing is recommended.
The combination HIV-1/HIV-2 includes detection of subtypes of HIV-1 not included in HIV-1, EIA alone. Repeatedly positive results are confirmed utilizing a different assay.
