of platelet aggregation and plasma coagulation time. Platelet-rich plasma (PRP) is obtained from freshly derived human whole blood and incubated with nanoparticles. Then the plasma is examined using a particle count and size analyzer to determine the number

Analysis of the Protein S Gene in Protein S Deficiency

Protein S (PS) is a 71-kDa vitamin K-dependent glycoprotein first identified in human plasma by DiScipio and colleagues in 1977 (1 ), a year after the discovery of the anticoagulant protein C (PC) (2 ,3 ). A few years later, Walker

血浆凝血酶原时间测定操作规程（检验SOP）

一、项目名称： 血浆凝血酶原时间测定（prothrombin time ，PT） 二、检验方法名称： 凝结法 三、方法学原理： 在确定量的血浆样本经过一定时间的加温后，加入试剂。加入试剂后，采用波长为660nm的光照射样本。凝血过程（纤维蛋白原转化为纤维蛋白）中血的浑浊度可以通过测量散射光光强度的改变来测定。从散射光光强度的测定，可以做出凝血曲线，通过Percentage Detection Method法求得凝血时间。 四、方法学溯源： 凝血
