URIT 11F dipstick for proteinuria testing: comparison with quantitative protein assay and evaluation of the diagnostic accuracy for proteinuria detection in a outpatient population

T. Köken \| N. Doğan \|
<p>The purpose of this study is to evaluate the diagnostic performances of URIT 11F urine dipstick assay for the<br />detection of proteinuria comparing it with a quantitative method. 5743 urine test results [urine dipstick, urine protein<br />and creatinine concentrations and the calculated protein to creatinine ratio (PCR)] were collected from outpatients<br />with various clinical conditions. The agreement between the URIT 11F urine dipstick and quantitative protein assay<br />was examined. To evaluate the accuracy of urine dipstick results for proteinuria detection, we used two different cutoffs:<br />PCR ≥200 mg/g and ≥150 mg/g. Dipstick test results (negative, trace, 1+, 2+, 3+) were allocated to five levels<br />of urine protein concentration (<14, 14-30, 30.1-100, 100.1-300, >300 mg/dL) respectively. There was an agreement<br />with a Kappa coefficient of 0.341 and p<0.001. When PCR ≥200 mg/g was used as cut-off and “> negative” was<br />classified as a positive dipstick result, the agreement of the URIT 11F dipsticks improved substantially. The findings<br />of our study show a fair agreement between URIT 11F dipstick results and the quantitative method for urine protein.<br />However, our results show also a high number of false negative results with dipstick testing. While second level<br />laboratory testing can eliminate the false positive results, false negative results could cause a delay in beneficial early<br />treatment of incipient nephropathy. For this reason, more sensitive proteinuria screening test for patients with<br />potential early stage renal diseases should be used.</p>
