  • This report reviewed the efficacy of nucleic acid testing (NAT), derived from assaying and measuring data, using a Cobass201 system at the Dongguan blood center from 2008 to 2017. During this period, four blood screening models, each reflecting procedure improvements designed to improve residual risk (RR) assessment were assessed. A total of 716 846 blood donors were screened, detecting 1 395 positive by the mixed pool test, which were finally modified to 900 positive cases, after final detection by the separation-single test: detecting 6 HIV cases, 4 HCV cases and 890 HBV cases with a total positive rate of 1.25%. The lowest result was obtained from the twice administered enzyme-linked immunoassay (ELISA) test,used in conjunction with the single Cobas MPX v2.0 model,with rates of: 1/7 405 for HBV, 1/346 020 for HCV and 1/473 934 for HIV, respectively. NAT positive rate is not affected by different screening models. NAT is a recent detection method which can be used to good effect with ELISA, and is a worth while procedure for promoting blood transfusion safety.
