Median Urine Leukocyte Values of Patients With Urinary Tract Infection and Controls (With Subgroups), Measured by Automated Microscopy and Urine Flowcytometry

n | 56 | 18 | 24 | 57 |
Automated microscopy in cells/µL, median (IQR) | 900 (430–900) | 296 (49–773) | 4 (1–30) | 18 (5–57) |
Urine flowcytometry | ||||
n | 35 | 17 | 24 | 58 |
Urine flowcytometry in cells/µL, median (IQR) | 1575 (581–4673) | 197 (43–1368) | 6 (1–35) | 20 (4–88) |
All values are expressed as median (IQR) as leukocyte values did not follow a normal distribution. The UTI column contains patients with both lower and upper UTI. Urine flowcytometry data were missing for 28 patients with UTI as they were included in regional hospitals in which urine flowcytometry was not available. For automated microscopy values, 900 cells/µL was the upper limit of detection. Abbreviations: ASB, asymptomatic bacteriuria; IQR, interquartile range; UTI, urinary tract infection.
