游离胆红素含义及其影响因素关于胆红素在血液中存在的方式,传统上是以凡登白反应阳性或阴性区分的。阳性系指与葡萄糖醛酸结合为酯的形式,称为直接胆红素;阴性是指不与葡萄糖醛酸结合,称为间接胆红素(unconjugatedbilirubin)。前者占97%,后者仅为3%。近年来,认为比这种分类法更简便的是,以血中呈游离状态的胆红素(unbound bilirubin,UB)和与白蛋白等呈结合状态的胆红素来区分。尽管UB量在血液中
The meaning of free bilirubin and its influencing factors The way in which bilirubin is present in the blood is traditionally distinguished by the Fondonbill reaction. Positive refers to glucuronic acid combined with ester form, known as direct bilirubin; negative is not glucuronic acid combination, called indirect bilirubin (unconjugatedbilirubin). The former accounted for 97%, while the latter only 3%. In recent years, it is considered more convenient than this classification method to distinguish between unbound bilirubin (UB) in the blood state and bilirubin that binds to albumin and the like. Despite the amount of UB in the blood
