The Diagnostic Accuracy of a Urine Albumin-Creatinine Ratio Point-of-Care Test for Detection of Albuminuria in Primary Care

The instrument-read reagent strip test was a poor rule-in test for albuminuria at the point of care, as evidenced by the low positive predictive value, but was a reasonable rule-out test. Observed sensitivity was lower than reported in earlier laboratory-based studies. This decreased diagnostic accuracy needs to be balanced against the potential advantages of a point-of-care testing approach.
