Utility of Untimed Urinary Albumin Measurements in Assessing Albuminuria in Black NIDDM Subjects

Abstract

The A-to-C ratio obtained from an untimed morning urine specimen correlates with the AER from a 24-h collection. In black subjects with newly diagnosed NIDDM, microalbuminuria is not present to a significant degree. Duration of NIDDM > 5 years is associated with increased prevalence of microalbuminuria, and hypertension is associated with microalbuminuria and clinical proteinuria in this population.
