It is well known that ABH group specific substances are usually present in high concentrations in body fluids of secretors. In normal circumstances these substances can withstand drying and retain their antigenic activity over a prolonged period. This enables the forensic serologist to assist in the investigation of various crimes by grouping stains of body fluids such as semen and saliva. It is possible, for instance, to group saliva and lip mucosa stains on cigarette ends, gags, masks, postage stamps and envelope flaps etc. but it is the grouping of seminal stains in the investigation of sexual crimes which predominates. The results of such tests can be extremely valuable in either including or excluding suspects.
众所周知，ABH血型特异性物质通常在分泌者的体液中以高浓度存在。在正常情况下，这些物质能够耐受干燥，并在较长时间内保持其抗原活性。这使得法医血清学家能够通过对精液和唾液等体液污渍进行分型，协助调查各类犯罪。例如，对烟头、堵嘴物、口罩、邮票和信封封口处等上面的唾液和唇黏膜污渍进行分型是可行的，但在性犯罪调查中，精液污渍的分型最为重要。此类检测结果在排除或确定嫌疑人方面可能极具价值。
