Urine β-galactosidase

β-galactosidase is a hydrolytic enzyme in the lysosome of the cell, and it is higher in the renal proximal tubule epithelial cells. Β-galactosidase activity in urine can reflect the renal parenchyma, especially the early damage of renal tubules. It can be measured with urine N-acetyl β-D-aminoglucosidase for urinary enzyme profiling, which is helpful to observe the course and prognosis Evaluation.
