红细胞沉降率(下称血沉)的测定方法有多种,但普遍采用的仍为魏氏法。该法通常以3.8％柠檬酸钠溶液作抗凝剂,使用此种溶液作抗凝剂存在以下问题:(1)抗凝剂与全血之比例往往不易精确控制,从而影响测定结果之重现性。(2)病房抽血时,在携带与转送实验室过程中不够方便。(3)用血量较多,为使准确加入1.60毫升全血,有时因空针漏气等原因,往往需抽血2.0毫升。由于以上原因,我们试用生化实验室中通用的含草酸钾粉末的抗菌素小瓶(将10％草酸钾1滴注入小瓶中于80℃烘干)作抗凝剂,
Erythrocyte sedimentation rate (hereinafter referred to ESR) determination of a variety of ways, but the commonly used method is still Wei’s. The method is usually 3.8% sodium citrate solution as anticoagulant, the use of such solution as anticoagulant the following problems: (1) the ratio of anticoagulant and whole blood is often not easy to accurately control, and thus affect the reproducibility of the measurement results Sex. (2) ward blood, not easy to carry and transfer laboratory process. (3) with more blood, in order to accurately add 1.60 ml of whole blood, and sometimes due to empty needles and other reasons, often need to take blood 2.0 ml. For the above reasons, we tried antibacterial vials containing potassium oxalate powder commonly used in biochemical laboratories (one drop of 10% potassium oxalate into a vial and dried at 80 ° C)
