If the donor’s HBsAg reactivity is unconfirmed and anti-HBc is nonreactive, then the donor may be retested after 8 weeks and reinstated if HBsAg and anti-HBc are nonreactive. This retest may occur as per routine testing of a new donation. ...
特异性:目前的各种检测方法均有出现假阳性结果的可能性,这种情况在弱反应性的标本中更为常见。因此,有必要对HBsAg测定呈现有反应性(特别是弱反应性)的标本进一步进行确认试验HBsAg测定中的问题HBsAg测定结果的解释(国外试剂盒)AbbottMurex(ELISA)样本A值<Cut-off(阳性判断值)非反应性(non-reactive)阴性结果(negative...
Specimens with a cut-off index (signal/cut-off value) < 0.90 were classed as nonreactive, and considered negative for HBsAg. These specimens did not require further testing. The kit insert states that specimens with a cut off index ≥ 0.90 and < 1.0 are considered borderline, and should ...
The result of a sample is given either as reactive or non-reactive as well as in the form of a cutoff index (COI) = (signal sample/cutoff). The cutoff index is needed for selection of the correct sample pretreatment volumes for the confirmatory test. Limitations - interference Due to the...
We recently found that O-glycosylated M-HBsAg, reactive with jacalin lectin, is one of the primary components of HBV DNA-containing virus particles. Thus, we aimed to analyze and target the glycosylation of HBsAg. Methods HBsAg prepared from the serum of Japanese patients with HBV were analyzed...
