Multicentre evaluation of the urine analyser Miditron Junior

Area of Science:

• Clinical chemistry
• Urinalysis
• Medical diagnostics

Background:

• Urine analysis is crucial for diagnosing various medical conditions.
• Accurate and reliable urine analysers are essential for effective patient care.
• Semi-quantitative urinalysis provides rapid screening results.

Purpose of the Study:

• To evaluate the accuracy and precision of the Miditron Junior urine analyser.
• To assess the performance of the Miditron Junior across multiple laboratory settings.
• To determine the reliability of semi-quantitative results for common urine analytes.

Main Methods:

• Multicentre evaluation involving four laboratories.
• Comparison of Miditron Junior results with quantitative chemical, physical, and microscopic methods.
• Assessment of accuracy using agreement within identical or neighbouring concentration blocks.
• Evaluation of within-run precision (repeatability) and day-to-day precision.

Main Results:

• Agreement with reference methods ranged from 79% to 99% for tested analytes.
• Within-run precision showed results falling within the same or adjacent concentration blocks.
• Day-to-day precision demonstrated results within +/- one colour block from the mean.
• The analyser provides semi-quantitative results for erythrocytes, bilirubin, urobilinogen, ketone bodies, glucose, protein, nitrite, leukocytes, pH, and relative density.

Conclusions:

• The Miditron Junior urine analyser demonstrates acceptable accuracy and precision for semi-quantitative urinalysis.
• The multicentre evaluation confirms its reliable performance in diverse laboratory environments.
• This analyser is a valuable tool for routine urine screening and diagnostics.
