Centralized blood nucleic acid test data in Tibet: a retrospective analysis
Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 8
Abstract
Objective To retrospectively analyze the serological and nucleic acid testing(NAT) data of voluntary blood donors from six blood banks in Tibet, in order to explore the positive impact of NAT on reducing the risk of infective transfusion in a regional scope. Methods From 2018 to 2022, 38 718 voluntary blood donors from blood centers of Tibet, Shannan, Shigatse, Naqu, Nyingchi and Ngari were tested for hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV), human immunodeficiency virus antigen (HIV) and antibody (Ag/Ab1+2) serological determination by enzyme-linked immunosorbent assay (ELISA). At the same time, Haoyuan and Daan nucleic acid detection systems were used for the combined detection of HBV-DNA, HCV-RNA and HIV-RNA. The results of NAT of reactive ELISA samples were statistically analyzed. Results A total of 178 ELISA-/NAT+ samples were detected in Tibet over the past five years, including 170 HBV-DNA positive cases, 8 HCV-RNA positive cases, and 0 HIV-RNA positive cases, with the positive rate at 0.460%.The detection rate of 624 ELISA+/NAT+ samples was 1.61%.The age of blood donors with hepatitis B in Shigatse area was slightly higher than that in other areas, and the difference was statistically significant(P<0.05) . Conclusion The centralized detection of viral nucleic acid in Blood Center of Tibet Autonomous Region can effectively reduce the missed detection of transfusion transmitted diseases and guarantee the blood safety in the region.
