摘要 目的探讨不同保存时间对腹水腺苷脱氨酶(adenosine deaminase,ADA)活性的影响。方法收集结核性腹水患者腹水标本10份、恶性肿瘤患者腹水标本6份和肝硬化患者腹水标本6份,将1 h内ADA活性测定结果作为对照,分别在第1、2、3、7、10天对保存在-20℃的标本进行ADA活性检测,比较不同时间点测定结果与1 h内测定结果的差异和相关性。结果不同放置时间ADA活性和1 hADA活性的差异无统计学意义(均P>0.05);第1、2、3、7天ADA活性和1 h内测定结果的相关系数大于0.9(均P<0.01),第10天小于0.9(P<0.01)。结论腹水样本放置于-20℃,10 d内ADA活性改变无统计学意义,不影响检测结果。
