摘要:
目的 研究脂肪血标本对凝血结果的干扰,并探讨血浆稀释法和高速离心法消除脂肪血标本的效果对比研究。方法 收集2017年1月~2019年12月期间健康体检者血浆标本100份(正常对照组),用脂肪乳配制成轻度脂肪血组(TG为3.955±1.053mmol/L)、中度脂肪血组(TG为8.020±3.126mmol/L)及重度脂肪血组(TG为22.712±5.013 mmol/L),分别检测三酰甘油(TG)、凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、血浆纤维蛋白原定量测定(FIB)和D-二聚体(DD)的浓度;再选取临床脂肪血标本78 份(研究组),包括中度脂肪血组42例和重度脂肪血组36例,通过血浆稀释法和高速离心法对其进行处理并检测,运用t 检验分析对比处理前后各组的差异性。结果 在不同程度模拟脂肪血中,中度脂肪血组和重度脂肪血组中PT,APTT,FIB检测水平均高于正常对照组(TG< 1.7mmol/L)和轻度脂肪血组,DD检测结果均低于正常对照组和轻度脂肪血组,差异均有统计学意义(t=-6.318~2.106,均P<0.05)。用血浆稀释法和高速离心法对78例中度、重度脂肪血标本进行处理,两种方法与处理前检测结果比较PT,APTT,FIB和DD检测结果差异有统计学意义( t=-4.225~8.655,均P<0.05) ,但这两种方法之间各项指标检测结果差异均无统计学意义(均P>0.05);用血浆稀释法对血凝仪器进行线性及精密度验证,结果都满足实验室要求。结论 血浆稀释法和高速离心法都能有效消除中度和重度脂肪血标本对凝血检测结果的干扰,但血浆稀释法无需高速离心,操作更简单,避免了基质效应,在消除脂肪血标本中有巨大的潜能。
