1Assuming 63 days of average duration for transient antigenaemia [8], that is, 63/329. 2Assuming 75% of blood donors with ELISA detectable HBsAg8. 3Confidence interval. 4Reciprocal value of the probability of detecting HBV seroconversion by stand-alone HBsAg test, that is, 1/0.. 5Assuming Poisson distribution for one HBsAg seroconverting case. |
