Abstract
Leucocytes and bacteria in urine are the important indices for diagnosing urinary tract infections. Urine specimens from 260 patientswere examined for leucocytes and bacteria with the UF-100 flow cytometer (Sysmex Corporation, Japan). The results obtained with the UF-100 were compared with those obtained by bacteriologic cultures of the same urine samples. Bacteriologic samples were found to be positive in 48 urine samples. The best detected cut-off value for bacteria is 3800/μL (senstivity = 73%, specificity = 78%) and 25/μL for leucocytes (sensitivity = 73%, specificity = 92%). In addition, comparison of leucocyte count by manually and with UF-100 shows good correlation (r = 0.91). A flow cytometric urinalysis analyzer operates in a time saving manner, increases throughput and decrease microscopy review rates. It also provides a reliable information to clinicians prior to bacteriologic culture results, in terms of leucocyte and bacteria count.
