The study concluded:
- The auto verification criteria for iRICELL urinalysis workcell can improve the efficiency of urine tests, reduce manpower and ensure the reliability of the test results
- Taking manual microscopic examination results as the gold standard, the auto verification criteria of iRICELL urinalysis workcell were initially established. The auto verification pass rate was 52.51% (1,811/3,449); the microscopic examination rate was 2.58% (89/3,449); and the false negative rate, false positive rate, true negative rates and true positive rates were 2.26% (78/3,449), 11.86% (409/3,449), 47.00% (1,621/3,449), and 38.88% (1,341/3,449) respectively
- A total of 20 independent auto verification criteria were determined, including 17 screen review criteria, 2 microscopic examination criteria and one dry chemical confirmation criterion
- The effective interception rate, invalid interception rate, effective verification rate, invalid verification rate and auto verification pass accuracy rate were 38.52% (599/1,555), 10.35% (161/1,555), 49.07% (763/1,555), 2.06% (32/1,555) and 87.59% (1,362/1,555) respectively
- With the application of the auto verification criteria, the rate of manual microscopic re-examination is notably lowered
