其中,TP表示真阳性(true positive),FN表示假阴性(false negative),TN表示真阴性(true negative),FP表示假阳性(false positive),n为样本数量。进一步采用Kappa检验评价试剂盒检测结果的一致性,若Kappa值<0,则一致性为极差;若Kappa值为0~0.20,则...
False‐positive reactions were not observed with K99‐negative strains and with several viral antigens. Only bovine coronavirus caused slight positive reactions which could be eliminated by a blocking test. As compared with the conventional procedure for the detection of the K99 antigen, ELISA seemed...
