Abstract:
Background: Nucleic acid testing (NAT) has been widely used for transfusion - transmitted infection screening at blood banks all over the world to reduce window period, yet the assay has not been implemented in Vietnam. Objective: Using and evaluating cost - effectiveness of NAT in screening HIV, HCV, HBV in blood \r\n', u'donors. Subjects and methods: The study was carried out on 9392 blood donors at National Institute of Hematology and Blood Transfusion from Jan to May 2007 who were HIV, HCV, HBV negative with ELISA. Plasma from donors was pooled (pool size of 8) and tested with UItrio Procleix HIV - 1, HCV, HBV (Chiton). Results: These 9392 plasma samples were pooled into 1174 pool samples to perform NAT. Among 1174 pooled samples, there was only 1 case with negative ELISA - Reactive NAT. The sample was determined as response with probe HCV. From there, one of eight pool samples was identified responding to probe HCV and it was more likely to have been missed in the window period when screened by ELISA.Conclusion: The sample should be further tested with HCV qualitative and quantitative testing to confirm the status of infection. \r\n', u'\r\n', u'
