Ann Clin Microbiol 2021;24:83-96. Evaluation of Five Automated Urine Analyzers as Screening Instruments for Enhancing Diagnostic Efficiency in Urinary Tract Infection
| Characteristic | Analyzer | Male (n = 307) | Female (n = 203) | P-value§ |
|---|---|---|---|---|
| Age (yr) | 59 (43-70) | 61 (46-71) | 0.985 | |
| Significant bacteriuria | 23 (7.5) | 48 (23.6) | < 0.001* | |
| WBC (/µL) | UF-5000 | 2.50 (1.00-7.85) | 4.60 (1.30-17.40) | 0.539 |
| UAS800 | 1.10 (0.00-6.44) | 3.30 (0.00-10.56) | 0.034* | |
| Cobas®u701 | 1.98 (0.00-6.44) | 3.96 (1.32-13.86) | 0.096 | |
| iQ®200SPRINT | 5.56 (0.00-11.12) | 5.56 (0.00-17.60) | 0.441 | |
| URiSCAN®PlusScope | 0.22 (0.00-2.05) | 2.05 (0.00-6.15) | 0.440 | |
| Bacteria (/µL)†,‡ | UF-1000i | 8.20 (3.10-27.30) | 15.50 (5.10-107.80) | 0.021* |
| UF-5000 | 2.30 (1.10-8.00) | 8.00 (2.30-63.50) | 0.020* | |
| UAS800 | 125.40 (58.19-207.40) | 110.00 (55.88-211.64) | 0.963 | |
| iQ®200SPRINT (ASP) | 1166.50 (471.75-2914.25) | 927.00 (463.00-2478.00) | 0.162 |
Values are presented as median (IQR) or number (%).
*P-value < 0.05 represents statistical significance.
†For bacteria count, the UF-1000i was also evaluated as a reference analyzer for comparison.
‡The Cobas® u701 and URiSCAN® PlusScope did not display the quantitative bacterial counts when our experiment was conducted. The iQ®200SPRINT provided ASP values instead of bacterial counts.
§The P-value stands for the statistical difference between genders.
Abbreviations: IQR, interquartile range; WBC, white blood cell; ASP, all small particle.
