射香草酚浊度试验:(常简写为 T.T.T)在正常人的血清中加入射香草酚缓冲液以后,溶液仍保持澄清或轻微混浊。但当肝脏受到损害后,由于血清中某种物质或蛋白的改变(其原理,学者还没一致意见),则随着肝脏的损害程度而发生不同程度的混浊,其混浊程度以麦文莱根氏单位计算。我国正常人血清,据史济招等氏报告为2.2～10.5单位, Turbidiol turbidity test: (often abbreviated as T.T.T) The solution remained clear or slightly turbid after the addition of thymidine buffer in normal human serum. However, when the liver is damaged, due to the change of a certain substance or protein in the serum (the principle has not been agreed by the scholars), there will be different degrees of turbidity with the degree of damage of the liver, and the degree of cloudiness will be that of Mawenglaigen. The unit of calculation. The normal human serum in China is reported to be 2.2 to 10.5 units, according to Shi Ji Zhao et al.
