用于临床医学检验中凝血机制(PT，APTT、凝血因子)检验，柠檬酸钠浓度为109mmol/L，采集血液与抗凝剂的比为1：9 ， 双层塑料管内管材质为PP(聚丙烯)，防止了液体添加剂的逐渐蒸发，保证了柠檬酸钠溶液浓度的长期稳定，另外，干燥的表面对于获得准确可靠的测试结果是有利的

外层管的材质是PET，保证了真空在保质期内的长期稳定，以PET和PP为材质的采血管可承受2500-3000g纵向的相对离心力，以获得不含血小板的血浆(PFP)

t is used for the test of blood coagulation mechanism.sach as PT,APTT.The citrate concentrationis 109mollThe mixing ratio is  9 pan citrate solution to I parts blood.The inner tube is made of PP materials,which can prevent the evaporation of liquid additive,and  keep the concentration of sodium citrate solution stable.Purthermore.the dry surface is favorable to obtain accurate testing result.The  outer tube is made of PET materials,which can maintain the vacuum stable in the shelf lfe period.The double layer tube can bear the  relative centrifugal force with 2500-3000g to obtain platelet-free plasma(PFP).
