HCV: Hepatitis C Virus (HCV) is the major cause of hepatitis. Making positive HCV Ab tests reflex to confirmatory molecular testing is necessary to confirm active HCV infection. Providing a second reflex to perform genotyping on HCV isolates when RNA is detected is also a necessary step before starting therapy. This double reflex will reduce the percentage of antibody-positive patients who lack appropriate confirmatory RNA testing and who do not have genotype testing performed. HIV: This 4th generation HIV Ag/Ab Combo assay is intended to be used as an aid in the diagnosis of HIV1/HIV2 infection, including acute or primary HIV-1 infection.

HIV tube must be labeled with patient identifier and submitted only
for HIV testing. Tube should be spun after clotting and remain
unopened.
