摘要
对我国凝血酶原时间（ＰＴ）测定进行了试验情况的书面调查，调查显示我国地区级以上大中型医院有８３．９％仍用手工法进行ＰＴ测定，其参考值最短只有６秒，最长达１７秒。试验调查用相同的凝血活酶与参考品，最长与最短ＰＴ值相差２．５倍，表明ＰＴ测定的规范化、标准化亟待解决，笔者提出了我国凝血酶原测定试剂及操作规范化的建议。
he result-of a corresponding survey of prothrombin time assay in China shows that in 83.9%of large and medium hospital the assay is still performed with manual method.The results were quite dis-pere ranging from 6～17 seconds. Using the same thromboplastin and reference material in all partici-pants to survey PT test, the maximum value is equal to 2. 5 times the minimum value. It indicated that the standardization of PT assay is urgent. The standardization of reagent and performance in PT assay in China is proposed in this paper.
