Abstract:
In Korea, external quality assessment trials for urinalysis and faecal occult blood (FOB) were performed for 1,250 participants. Urine chemistry and FOB tests were evaluated three times, whereas urine sediment by photography was evaluated twice. Urine chemistry tests consisted those for pH, protein, glucose, ketone, bilirubin, blood, urobilinogen, nitrite, leukocyte, and specific gravity. The results of the urine chemistry and specific gravity tests showed accuracy rates >95%. In the FOB quality test, all reagents showed false-positive results. These reagents showed positive results in stool specimens containing >11 ng/mL haemoglobin. In the FOB quantitative test, the results were significantly different, based on the instrument used for the measurements. The average accuracy rate of urine sediments was 90.8%, whereas those for renal epithelial cells and cholesterol crystals were 83%.
