Objective To evaluate the differences of domestic chemiluminescence( CLIA) reagent in hepatitis B and HIV blood screening by comparing using enzyme-linked immunosorbent assay( ELISA) and nucleic acids( NAT) detection.Methods A total of 2 163 donor samples were tested for HBs Ag and anti-HIV detection through parallel detection by ELISA,NAT and chemiluminescence assays. The HIV reactive samples were confirmed by Western blot( WB). A quantitative detection of HBs Ag was conducted using Roche and Abbott for co...
