A sandwich enzyme immunoassay for the detection of p30 prostate specific antigen was applied in 52 forensic cases. In each case, immunoassay results were compared with those of the search for spermatozoa and prostatic acid phosphatase analysis. The results indicate that the p30 assay gave no false positive and fewer false negative reactions than the acid phosphatase test. The sensitivities compared to the search for spermatozoa as a reference method were 94.8% for the p30 assay and 84.4% for the acid phosphatase test; the specificities were 95.6% and 90.0% respectively.
一种用于检测p30前列腺特异性抗原的夹心酶免疫测定法应用于52例法医案件。在每个案件中，将免疫测定结果与精子搜索结果及前列腺酸性磷酸酶分析结果进行比较。结果表明，与酸性磷酸酶检测相比，p30检测未出现假阳性，假阴性反应也更少。以精子搜索作为参考方法，p30检测的灵敏度为94.8%，酸性磷酸酶检测的灵敏度为84.4%；特异性分别为95.6%和90.0%。
