Unsatisfactory performance of flow cytometer UF-100 and urine strips in predicting outcome of urine cultures.
UF-100 flow cytometer and urine strip results were cross-interpreted to predict culture outcomes. The best negative predictive value was obtained with bacteria at > or =1,000/microl, white blood cells at > or =20/microl, or leukocyte esterase positivity. Nine of 24 false negatives were clinically significant. Thus, UF-100 and urine strip results do not accurately predict the outcome of cultures.
متن کاملReference values for neonates and children for the UF-100 urine flow cytometer.
The UF-100 fully automated urine flow cytometer classifies urinary particles on the basis of their light scattering, fluorescence, and impedance properties. The UF-100 counts erythrocytes, leukocytes, bacteria, epithelial cells, and casts. The operating principles of the UF-100 and its precision, accuracy, and analytical sensitivity have been published previously (1–4). The high sensitivity of ...
متن کاملLeukocyte counts in cerebrospinal fluid with the automated hematology analyzer CellDyn 3500 and the urine flow cytometer UF-100.
BACKGROUND The counting of leukocytes and erythrocytes in cerebrospinal fluid (CSF) is still performed microscopically, e.g., using a chamber in most laboratories. This requires sufficient practical experience, is time-consuming, and may constitute a problem in emergency diagnostics. Specific automated systems for CSF cell counting are not available at present. METHODS We tested the hematolog...
متن کاملAutomated urinalysis: first experiences and a comparison between the Iris iQ200 urine microscopy system, the Sysmex UF-100 flow cytometer and manual microscopic particle counting.
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 3...
