In two separate moves, the FDA has approved the first assay to detect both antigen and antibodies to HIV and the first rapid blood test for hepatitis C virus (HCV) antibodies.
The Architect HIV Ag/Ab Combo assay is approved for the diagnosis of HIV-1/HIV-2 infection in adults, including pregnant women. It is also the first assay for use as an aid in HIV-1/HIV-2 diagnosis in children as young as age 2 years.

The OraQuick test is approved for use only in people at risk for HCV infection or those with suspected hepatitis and is not intended for general-population screening purposes.
