RESUMEN
ObleetiveTo study the efficacy of flow cytometry in measurement.of urinary RBC. MethodsA total of 1 318 urine samples were analyzed by using the UF-50 urinary sediment analysor and microscopic examination respectively. ResultsThe positive rate of red blood celI(RI3C) in urinary sediments tested with UF-50 analysor was 13.05%, higher than that by microscopic examination as the'standard(9.18%). Their positive coincidence was 70%. ConclusionThe detection of RBC with UF-50 analysor is influenced by crystals, yeast fungi, infusorium, fat drops, sperma and bacteria, which may lead to false results. Fully automated urinalysis analyzer can not replace the microscopic exmination, but it has very important clinical value as a sieving and monitoring means.
