　　凝血酶原时间小于25秒提示凝血酶原消耗不佳在给予凝血因子后消耗不佳的凝血酶原时间得以纠正\\
　　凝血酶原时间小于25秒提示凝血酶原消耗不佳在给予凝血因子后消耗不佳的凝血酶原时间得以纠正。利用贮存血浆中含因子Ⅱ，正常吸附血浆中含因子Ⅴ，正常血清含因子Ⅶ和Ⅹ，正常新鲜血浆含所有血浆凝血因子，来纠正延长的PT，从而找出凝血酶原时间延长的原因。\\

标本采集：静脉采血时要一针见血，尽量减少组织液和气泡混入，避免溶血。沿管壁将静脉血注入试管。温度要恒定，过高或过低均可使凝固时间延长。4.注射器和试管均应保持干燥、清洁、否则会加速凝血和发生溶血。试管口径大小均应适当，管径越大，凝血时间越长。\\
标本运送：采集后应立即检测，否则凝血时间延长。
