| Popis: | Objective To discuss the reliability and applicability of the current blood deferral strategy concerning anti-TPreactive blood donors (by ELISA). Methods TPPA confirmatory test was performed on the samples routinely detected by two different anti-TP ELISA reagents(reagent 1 and reagent 2), and the test data of dual reagent reactive and one reagent reactive blood donors were analyzed to determine the possibility of true positivity. Results 1 624 anti-TP reactive samples(by ELISA) were collected, among which 1 467 were dual reagent reactive, 77 were reagent 1 reactive, and 80 were reagent 2 reactive. TPPA results showed that the positive predictive value (PPV) of dual reactive samples was 85.48%. Samples with high S/CO value (reagent 1≥13 and/or reagent 2 >17) were more likely to be true positive, with the PPV at 98.56% (reagent 1) and 99.13% (reagent 2), respectively, which were significantly higher than that when the S/CO value was≥1. Among the samples reactive to one reagent, 2 were confirmed positive in reagent 1 and 3 in reagent 2, with the PPV at 2.60% and 3.75% respectively, and had no correlation with high S/CO value. Conclusion Dual-reagent reactive donors with high S/CO value showed high possibility of true positivity, therefore should be deferred. TPPA test is helpful to identify true positivity in one-reagent reactive donors. Confirmatory test and follow-up should be a supplement to the current blood donor deferral strategy to ensure blood safety. |
