ABSTRACT
In 2018, external quality assessment trials for urinalysis and fecal occult blood (FOB) were performed using 1,590 participants. Urine chemistry tests were performed thrice while urine sediment and FOB tests twice. Urine chemistry tests comprised of pH, protein, glucose, ketone body, bilirubin, blood, urobilinogen, nitrite, leukocyte, and specific gravity analyses. The results of urine chemistry and specific gravity tests showed accuracy rates >95%, except for the pH test. The accuracy rate of urine sediments was low, especially for atypical calcium oxalate crystal and red blood cell cast. In the FOB quality test, reagents showed accuracy rates >90%, except for SD and GC Genedia FOB reagents. In the FOB quantitative test, Alfresa NS-Plus C instrument showed falsely high values in the FOB negative specimens.
