Abstract:
In 2016, external quality assessment trials for urinalysis and faecal occult blood (FOB) were performed with 1,487 participants in Korea. Urine chemistry and FOB tests were performed three and two times, respectively, whereas urine sediment was evaluated once using photography. Urine chemistry tests consisted of pH, protein, glucose, ketone, bilirubin, blood, urobilinogen, and nitrite levels; leukocyte count; specific gravity. The results of the urine chemistry and specific gravity tests showed accuracy rates of >95%. The accuracy rate of urine sediments was low, especially that for transitional epithelial cells and atypical crystals. In the FOB quality test, all reagents showed accuracy rates of >90%, which suggested the improvement of false-positive reaction. In the FOB quantitative test, discrepant results depending on the instrument used was observed. To compensate for the result differences caused by the stool samples, the results should be reported using another unit (µg/g of stool).
