The modified zinc test and a commercially available acid phosphatase test were compared as to their screening parameters according to the microscopical finding of spermatozoa in cases of alleged sexual assault. The study involved 65 pieces of evidence material. It was found that the modified zinc te

✦ Synopsis
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.
