Urine N-acetyl-beta-D-glucosaminidase (UNAG)

Urine N-acetyl-β-D-glucosaminidase activity reflects renal parenchymal lesions and is particularly sensitive to acute injury and active phase, and can be used for early renal injury monitoring and disease course observation. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: normal. Normal value: Urine N-acetyl-β-D-glucosaminidase (fluorescence spectrophotometry): 3.20-9.58 U/L·Cr Above normal: Glomerulonephritis, lupus nephritis, congenital renal tubular disease, renal tubulointerstitial disease, renal failure, nephrotic syndrome, epidemic hemorrhagic fever. negative: Positive: Tips: Fresh morning urine should be used as much as possible. The urine that is randomly selected is preferably mid-stage urine. Women should avoid menstruation when taking urine specimens and should prevent vaginal secretions from mixing into the urine. Normal value 1, p-nitrophenol colorimetric method: urine NAG is normally distributed, the median is 9.13U / g creatinine, the 95th percentile upper limit is 16.10U / g creatinine. 2, fluorescence spectrophotometry: adult urine 6.39 ± 3.19U / L · Cr. Clinical significance Increase glomerulonephritis, lupus nephritis, congenital renal tubular disease, renal tubulointerstitial disease, renal failure, nephrotic syndrome, epidemic hemorrhagic fever. High results may be diseases: lupus nephritis, glomerulonephritis, renal failure precautions Note when checking: 1. Try to use fresh morning urine when doing this test. The urine that is randomly selected is preferably mid-stage urine. 2, women should avoid the menstrual period when taking urine specimens, should prevent vaginal secretions mixed into the urine, middle-stage urine is appropriate. 3.
