血块退缩定性试验是出血性疾病常用的检验方法之一。国内最常用的是试管法,需从静脉取血两毫升,经24小时可得出结果。为了节省血液和减轻病人的痛苦,我们设计了一种微量血块退缩试验,在末稍取血0.15毫升即可。其操作简便,使用器具少,操作步骤又与试管法大体相同,易于习惯推广。我们将微量法和试管法做了部份对照。 Blood clot qualitative test is one of the common testing methods for hemorrhagic disease. The most commonly used is the test tube method, take two milliliters of blood from the vein, the results can be obtained after 24 hours. In order to save blood and alleviate the suffering of patients, we designed a trace blood clot retraction test, 0.15 ml blood can be taken at the end. Its easy to operate, the use of less appliances, operating procedures and test tube method generally the same, easy to promote customary. We made a partial comparison between the microtitration method and the tube method.
