    Abstract:
    Albuminuria is a powerful predictor of cardiovascular events in diabetic and hypertensive patients as well as in the general population. In the present study we evaluated the diagnostic performance of the new PreventID Albumin test, a semi-quantitative immunochromatographic dipstick device for the rapid detection of low concentrations of urinary albumin (microalbuminuria). 88 randomly selected fresh urine samples from the central clinical laboratory of the Charité, Berlin/Germany were analysed. The diagnostic accuracy of the PreventID Albumin test for the detection of urinary albumin excretion >18 mg/l was assessed by comparing the results with urinary albumin excretion determined by immunoturbidimetry as golden standard. In comparison with immunoturbidimetry the PreventID Albumin test had a sensitivity of 96.2% and specificity of 97.1%. False negative results were found in 2.3% and false positive results were obtained in 1.1% of specimens. These findings suggest that the PreventID Albumin test may be a useful and valid method for the screening of albuminuria. However, it should not be regarded as a diagnostic test. Positive results should be followed by quantification of urinary albumin or albumin/creatinine ratio by a laboratory based method.
