ABSTRACT
Objective To explore the diagnosis value of joint detection of microalbumin(mALB) ,α1-Microglolin(α1-M ) and N-acety-β-D-glucosaminidase(NAG) in the diabetes and hypertension patients with early injury of kidney .Methods Sample were col-lected from July 2013 to January 2014 ,including 63 diabetic cases(diabetic group) ,58 patients with hypertension(hypertension group) and 64 health controls(control group) ,then the levels of urinary mALB ,α1-M were detected by immunoturbidimetry ,urina-ry NAG activity was assessed by endpoint colorimetric assay .Results The levels of urinary mALB ,α1-M and NAG in diabetic group and hypertension group were higher than those in control group(P<0 .05) .The positive rates of three indices single detected were less than 50 .0% ,the positive rates of any two indices joint detected were more than 50 .0% ,the positive rate of three indices joint detected was more than 70 .0% .Conclusion The method of urinary mALB ,α1-M and NAG joint detected is sensitive and reli-able for diagnosing of the early injury of kidney .
