Questionable usefulness of gamma-glutamyl transpeptidase test in legal medicine.
Because of the high level of GGT activity in semen, the suggestion was made that this enzyme could serve as a test in forensic medical practice; especially in rape cases. Comparisons of GGT and ACP tests revealed, however, that GGT is not sensitive enough and did not show acceptable specificity. One can conclude that GGT cannot be recommended either as a confirmatory test or as a substitute for ACP determinations in rape cases.
