N ACETYL BETA D GLUCOSAMINIDASE IN

The N-Acetyl Beta-D-Glucosaminidase (NAG) Test is a specialized urine test that measures the levels of the enzyme NAG in your urine. NAG is a lysosomal enzyme present in various tissues, including the kidneys. When kidney cells are damaged or under stress, they release NAG into the urine. Thus, elevated levels of NAG in the urine can indicate early kidney damage, even before other markers of kidney function show abnormalities.
