Human Retinol Binding Protein（RBP）Antigen, Native

Reference value: serum 25~70mg/L, urine < 0.7mg/L is used to detect retinol binding protein (RBP) in human serum or urine. RBP is a specific binding protein of vitamin An in blood, which plays an important role in the metabolism of vitamin A. it is synthesized by the liver and widely distributed in blood, cerebrospinal fluid, urine and other body fluids. The determination of RBP can detect the functional damage of renal tubules early and sensitively reflect the damage degree of renal proximal convoluted tubules. It can also be used as an index of early damage of liver function and monitoring treatment.
