Abstract:

Objective

To investigate the blood safety of single-HBsAg-reagent(+)/NAT(-) blood donors.

Methods

150 single-HBsAg-reagent(+)/NAT(-) blood donors (single-reagent(+) group) were tested for quantified HBsAg, HBsAb, HBcAb and two-half HBV detection from Jul 2020 to Apr 2022, which were compared with the control group of qualified blood donors.

Results

Quantified HBsAg of the single-reagent(+) group were all negative.The median value of HBsAg, HBsAb and HBcAb were 0.01 IU/ml, 51.368 mIU/ml and 0.212 PEIU/ml, respectively (P<0.05). The quantification of HBsAg and HBcAb, and the positive rate in the single-reagent(+) group were significantly higher than that in the control group (P<0.05). In the single-reagent(+) group, there was no difference in quantification and positive rate of HBV markers between first and multiple-time donors. There were 5 serological patterns in both groups, of which the model "2" was predominant. In the single-reagent(+) group, 16 donors who turned to qualified blood donors, and the quantitative value and positive rate of HBV markers showed no difference from the control group (P>0.05).

Conclusion

Single-HBsAg-reagent(+)/NAT(-) blood donors are mostly false positive for HBsAg, but they have a higher potential risk of transfusion-transmitting HBV than qualified blood donors.
