Urine glucose, proteins, albumin and creatinine are measured for the screening of diabetes and renal diseases. The automated strip analyzers are used for quick screening of large populations. The goal of this study was to compare a more accurate method, the Cobas 8000 (Roche, Bale, Switzerland) to three automated analyzers: the Clinitek Novus (Siemens, Munich, Germany), the UC-3500 (Sysmex, Kobe, Japan) and the AutionMax (Menarini, Florence, Italy).
A total of 284 urine samples were prospectively collected for the comparison. The samples were analyzed on the three analyzers within 2 hours. Before the analysis of samples by each method, an aliquot was frozen at -80°C. All samples were then defrost and analyzed in one batch with the Cobas 8000 (Roche, Bale, Switzerland) within the month. The diagnostic accuracy was determined thanks to the results of the Cobas 8000. However, the creatinine and albumin cannot be assessed with the AutionMax
