  1. Preparation of Standard Paneled Plasma for HBV, HCV, and HIV-1 in Japan Hisao Yugi Study Group of the Ministry of Health, Labour and Welfare, Japan Japanese Red Cross Central Blood Center

  2. Objectives To achieve the safety of blood products For standardizations and specifications of the NAT and serological test For evaluation of reagents

  3. Contents Virus : HBV, HCV, HIV-1 Source : Fresh frozen plasma from voluntary donated bloods Panels : 100 panels each including negatives undiluted fresh frozen plasma from each donors Test Items : NAT and serological tests

  4. HBV Panels Test Items Methods/Reagents TaqMan PCR(J), AMPLICOR HBV Monitor(R) HBV DNA HBsAg PRISM(A), AxSYM(A), ARCHITECT(A), Lumipulse(F), Vitros(O), HBsAg ELISA(O) anti-HBc AxSYM(A), Lumipulse(F), HBcAb ELISA(O) anti-HBs AUSAB(A), Lumipulse(F) IgM anti-HBc Lumipulse(F) Genotype DNA sequencing Subtype deduced from sequence Pre-C mutation DNA sequencing (A):Abbott, (F):FUJIREBIO, (J):JRC, (O):Ortho, (R):Roche

HCV Panel Test Items Methods/Reagents TaqMan PCR(J), AMPLICOR HCV Monitor(R) HCV RNA HCV core Ag Lumipulse(F), HCV Ag ELISA(O), HCV Ag IRMA(O) anti-HCV PHA(A), PA(F), Lumipulse(F), AxSYM(A), HCV Ab ELISA(O) anti-HCV core Lumipulse(F) WB RIBA(C) Genotype PCR (A):Abbott, (C):Chiron, (F):FUJIREBIO, (J):JRC, (O):Ortho, (R):Roche

  9. Preliminary Application Study • A nation-wide survey for HCV NAT • Coded panel for the survey • - Genotype 1b, 2a, 2b (200-300 IU/mL) • - Negative plasma • Participants: • - COBAS AMPLICOR : 92 HPs and Labs • - AMPLICOR (MWP) : 32 HPs and Labs

  10. Result • False negative result • - 1b : 2.4% (3/124) • - 2a : 6.5% (8/124) • - 2b : 2.4% (3/124) • - Neg : 0.0% (0/124) • 11 sites gave false negative results • 9 with COBAS, 2 with MWP Improvement ==>> No false negative nor positive result in 11 sites in the follow-up survey
