This study compares the detection of choline in seminal stains by both an enzymatic method and by the standard Florence crystal test. The tests were conducted on 293 actual casework samples. In those samples identified as containing semen, choline was detected twice as often by the enzymatic method compared to the Florence method (84.6 versus 40.3%). The choline results were correlated with spermatozoa and acid phosphatase tests. The enzymatic detection of choline in seminal stains was found to be a fast, easy, sensitive, and reliable test.
本研究比较了酶法和标准弗洛伦斯晶体试验对精液斑中胆碱的检测。对293份实际案件样本进行了检测。在那些被鉴定为含有精液的样本中，酶法检测胆碱的频率是弗洛伦斯法的两倍（分别为84.6%和40.3%）。胆碱检测结果与精子和酸性磷酸酶检测结果相关。精液斑中胆碱的酶法检测是一种快速、简便、灵敏且可靠的检测方法。
