Description

The Urine N-Acetyl-β-D-Glucosaminidase test helps detect early kidney tubular damage, especially in diabetes or hypertension; costs ¥15–45 at partner hospitals in China, with ChinaMedicalHub assisting with booking and interpreter support.

Main Uses

The primary purpose of the N-Acetyl-β-D-Glucosaminidase (NAG) test in urine is to assess kidney function, particularly the health of the renal tubules. It is used to detect early signs of kidney damage, monitor the progression of kidney diseases, and evaluate the effectiveness of treatments. This test is especially useful in diagnosing and monitoring conditions like diabetic nephropathy, acute and chronic kidney injuries, and drug-induced nephrotoxicity.

Normal Range

The normal range for N-Acetyl-β-D-Glucosaminidase (NAG) in urine is typically between 0.3 to 2.5 U/L, though this can vary slightly depending on the laboratory and the specific method used for measurement.

Low Values - Possible Causes

Low values of NAG in urine are less commonly a concern but may be associated with: 1. Overhydration, 2. Certain medications that reduce enzyme activity, 3. Rare genetic conditions affecting enzyme production, 4. Very low protein intake, 5. Lack of renal tubular damage or stress.

High Values - Possible Causes

High values of NAG in urine can indicate: 1. Acute kidney injury, 2. Chronic kidney disease, 3. Diabetic nephropathy, 4. Renal tubular disorders, 5. Exposure to nephrotoxic substances such as heavy metals or certain drugs.
