抗HCV抗体和抗TP抗体筛查试验的假阳性问题不容忽视

Pay close attention to false positivity in the determinations of anti-HCV and anti-TP antibodies

阐述了抗丙型肝炎病毒(HCV)抗体和抗梅毒螺旋体(TP)抗体筛查试验的假阳性问题和应对措施,强调检测抗HCV抗体和抗TP抗体应包括抗体的筛查试验和针对筛查呈重复阳性反应结果而进行的更特异的补充确证试验,旨在提请临床和采供血机构的免疫学检验工作者对抗HCV抗体和抗TP抗体筛查试验的假阳性问题予以足够重视。

The false positivity in the determinations of anti-hepatitis C virus（ HCV） antibody and anti-treponema pallidum（ TP） antibody and the correspondence measures for solving this problem are presented. It is emphasized that the determinations of anti-HCV and anti-TP antibodies should use an antibody screening assay and a specific supplementary confirmation assay for the results showing repeatedly positive reaction in screening assay. Immunology test technicians in clinic and blood collection agencies should pay close attention to false positivity in the determinations of anti-HCV and anti-TP antibodies,which also is the purpose of this article.
