Automated urinalysis: first experiences and a comparison between the Iris iQ200 urine microscopy system, the Sysmex UF-100 flow cytometer and manual microscopic particle counting

Abstract: Background: Automated analysis of insoluble urine components can reduce the workload of conventional microscopic examination of urine sediment and is possibly helpful for standardization. We compared the diagnostic performance of two automated urine sediment analyzers and combined dipstick/automated urine analysis with that of the traditional dipstick/ microscopy algorithm. Methods: A total of 332 specimens were collected and analyzed for insoluble urine components by microscopy and automated analyzers, namely… Show more

“…[5][6][7][8] In comparison to the study done by Shayanfar et al, most of the parameters showed similar results except for bacteria which was only 42% in their study where as in ours it was 90%. 6 However, the correlation of the bacteria present with the gold standard method of culture was not performed in our study.…”

“…[9][10][11] Conventional microscopic analysis of urine sediments although considered to be the reference method, in values several methodological steps such a centrifugation and discarding that lead to loss and destruction of cells and result in imprecision and inaccuracy. 6 These procedures are not required in the automated analysis. The turn-around time has markedly decreased and good reproducibility.…”

“…Urine microscopy fulfills all of these criteria. Furthermore, there is a trend toward automated microscopy at several hospitals in the United States (25,26). Although general clinicians depend on these automated systems, the performance of automated microscopy has not been thoroughly studied.…”

“…These methods, however, are still not qualified to detect and quantify urinary dRBC. The sensitivity and specificity of these methods to diagnose pathology are still under investigation, and manual microscopic examination is still required to identify some cell types [35]. The present study evaluated whether there is still reason to perform manual microscopic examination of urinary specimens in clinical practice.…”
