Nationwide nucleic acid amplification testing (NAT) for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus type 1 (HIV-1) of blood donated voluntarily after serological screening was implemented on July 1st 1999 for transfusion and plasma fractionation by the Japanese Red Cross blood transfusion services. From February 1st 2000, HBV, HCV and HIV-1 NAT screening of pools of 50 negative serologically screened donated blood was started and the results were reported within 1 day after blood donation. Systems were established for rapid shipment, electronic communication, automated specimen preparation, pooling and automated amplification and detection. ⋯ The NAT system was developed from serological screening test negative non-remunerated voluntary donations. We supply blood products to medical organizations after screening by NAT for HBV, HCV and HIV-1 for transfusion and source plasma for fractionation. This is the first automated integrated system for prevention of transfusion transmitted HBV, HCV and HIV-1 infections, by NAT screening.
