N-acetyl-β-D-glucosaminidase (NAG) is mainly used in the colorimetric assay for the determination of N-acetyl-β-D-glucosaminidase in urine. NAG hydrolyzes 3-cresolsulfonphthaleinyl-N-acetyl-D-glucosaminide to release 3-cresolsulfonphthalein, which is measured photometrically at 580nm. It is an intracellular lysosomal enzyme, present in the S3 segment of proximal tubular cells and distal nephron. Presence of NAG in the urine shows an organelle impairment in proximal tubule. Level of NAG rises in individuals over 70 years of age.
