Diagnostic value of urine trace protein test of the early kidney lesion among aged hypertension

Objective:To study the diagnostic value of renal trace protein test on early kidney lesion in aged patients with hypertension.Methods:Morning urine,vein blood at empty stomach of 95 aged essential hypertension(EH) patients were collected.Urine microalbumin(MA),both urine and blood β 2-MG were assayed with ELISA,blood BUN,Cr also assayed;when any of these index(MA,blood,urine β 2-MG) was positive,it was regarded as urine\|linked assay positive.Results:Positive rate of blood β 2-MG,urine β 2-MG,MA was 71.57%,68.42%,53.68% respectively,positive rate of urine-linked assay was 85.26%.Positive rate of these index was higher than urine routine test(14.73%),BUN?Cr(29.47%)( P 0.001);positive rate of urine-linked assat was 100% in patients with 2 and 3 stage EH.Conclusion:MA,blood?urine β 2-MG levels have earlier alteration than chaneg of BUN,Cr in aged EH patients with early kidney lesion.
