[Gm/Km determination in sperm traces].
In the forensic laboratories of the Federal Republic of Germany and West-Berlin 23 different semen stains and in our own laboratory 20 semen stains were typed in the gm/km-system doing 125 and 61 (own) test respectively. Examination was carried out by means of the haemagglutination method, which has been used successfully in typing bloodstains. Our critical assessment based on earlier experiences with semen stains was now confirmed and statistically evaluated: typing was successful in about 35-50% of the tests, but besides false-negative results, there was also a considerable percentage (4-10%) of false-positive ones. Therefore for the present it seems best to exclude the gm/km-typing of secretion stains from forensic investigations in order to avoid false incriminations or exonerations of suspects.
