title: [Detection of microalbuminuria using reagent tablets NIDDM: evaluation of the technique in primary care].
abstract: A qualitative technique for determining microalbuminuria (Micro-Bumintest) was compared with nephelometry testing in 129 DMNID outpatients with the purpose of validating the method in our medium. The sensitivity, specificity, and predictive values of the Micro-Bumintest are calculated with respect to 40, 20, and 17 micrograms/ml, which are figures that indicate a risk of early mortality and/or nephropathy. The sensitivity rates are 100, 85, and 69.2%, and the specificity 91.5, 96.3, and 97%, respectively. Our results were compared as well with those of other authors. The correlation between the Micro-Bumintest and nephelometry was 0.59 (p less than 0.005). The intra- and inter-observer variability is minimal. The conclusion that was drawn is that the Micro-Bumintest is reliable for concentrations greater than 40 micrograms/ml, losing some sensitivity in lower concentrations when applied in the control of primary care patients with DMNID.
