Urinary gamma-glutamyltransferase

Urine γ-glutamyltransferase activity reflects renal parenchymal lesions. It can be used as a differential index for renal transplant rejection and to assess the degree of renal water tube damage in patients with suspected kidney disease. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: No relevant information. Normal value: Urinary γ-glutamyl transferase: 10-50 U/L Above normal: Found in acute glomerulonephritis, lupus nephritis, pyelonephritis and other kidney damage caused by nephrotoxic substances and renal transplant rejection. negative: Positive: Tips: Reduce to kidney tumors. At present, it is clinically considered that patients with serum GGT values ​​above 150 U/L often have hepatobiliary diseases. Normal value 10.0 ~ 50.0U / L. Clinical significance (1) The activity of the enzyme in the urine is increased, which can be seen in acute glomerulonephritis, lupus nephritis, pyelonephritis and other kidney diseases caused by nephrotoxic substances and renal transplant rejection. (2) If there is urinary tract infection, the enzyme activity is normal in the case of cystitis, urethritis and other lower urinary tract infections, urinary bacteria culture can be positive, urinary leukocytosis can occur; pyelonephritis, interstitial nephritis and other upper urine In the case of road infection, the activity of the enzyme in the urine is increased, and may be accompanied by a cast. High results may be diseases: lupus nephritis, acute glomerulonephritis precautions Reduced to kidney tumors. At present, it is clinically considered that patients with serum GGT values ​​above 150 U/L often have hepatobiliary diseases. Inspection process Take 100 μL of the test specimen, add 1.0 ml of the substrate buffer pre-warmed at 37 ° C, and immediately inhale the analyzer. The dilution factor of the specimen is 11.
