【摘要】:目的探讨大鼠血清放置时间对14项血生化检测结果的影响。方法随机选取40只成年SD大鼠,空腹采集静脉血液标本,静置1 h,分离血清并密封分装,存放于4℃和-20℃冰箱内,应用全自动生化分析仪于分离血清后0 h、4 h、24 h、96 h、7 d检测谷丙转氨酶(ALT)、谷草转氨酶(AST)、碱性磷酸酶(ALP)、总蛋白(TP)、白蛋白(ALB)、肌酐(CREA-J)、尿酸(UA)、尿素氮(UREA)、血糖(GLU)、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、肌酸激酶(CK)和乳酸脱氢酶(LDH)等14项血生化指标,并进行比较。结果雌雄大鼠血生化数据变化趋势一致。4℃保存时,与0 h相比,ALP在4 h、24 h、96 h、7d均显著降低(P0.05),ALB在96 h和7 d均极显著升高(P0.01),CREA-J在96 h和7 d均显著升高(P0.05),UA在24 h、96 h、7 d均极显著升高(P0.01),其他指标差异无显著性(P0.05)。-20℃保存时,与0 h相比,ALT在7 d显著升高(P0.01),AST在96 h和7 d显著升高(P0.05),TP在4 h和24 h显著降低(P0.05),ALB在4 h、24 h、96 h、7 d均显著升高(P0.01),CREA-J在24 h、96 h、7 d均显著升高(P0.01),UA在4 h、24 h、96 h、7 d均显著升高(P0.01),TC在4 h、24 h、96 h、7 d均显著升高(P0.05),TG在96 h和7 d显著升高(P0.05),CK在96 h和7 d显著升高(P0.05),LDH在96 h和7 d显著升高(P0.05),其他指标差异无显著性(P0.05)。结论大鼠血生化测定尽可能在采集血清后即刻完成,尤其是ALP的测定,4℃冷藏时,测定UA不宜超过4 h,测定ALB和CREA-J不宜超过24 h,测定ALT、AST、TP、UREA、GLU、TC、TG、LDL-C、CK及LDH等指标不宜超过7 d。
