业已发现,以血浆为标准,用一期法和两期法测定因子Ⅷ浓缩物的因子ⅧC的结果,差别约为20％。为了研究造成这个差别的原因,本文作者采用一期法和两期法来研究氢氧化铝对血浆因子ⅧC抗原的吸附作用,并测定了吸附前、后血浆样品的因子ⅧC抗原。结果发现正常血浆样品和冰冻血浆样品经氢氧化铝吸附后,其因子ⅧC抗原有明显的损失(分别损失14.7％和25.2％),但
It has been found that the difference of about 20% for the determination of Factor VIII Concentration factor VIII C using the one-phase and two-phase methods with plasma as the standard. In order to investigate the reasons for this difference, the authors used a one-stage method and a two-stage method to study the adsorption of aluminum hydroxide on the plasma factor Ⅷ C antigen and determine the factor Ⅷ C antigen in plasma samples before and after adsorption. The results showed that the normal plasma samples and frozen plasma samples adsorbed by aluminum hydroxide, the factor Ⅷ C antigen significant loss (14.7% and 25.2%, respectively), but
