Abstract
|
|
|
|
In 2014, external quality assessment trials for urinalysis and faecal occult blood (FOB) were performed of 1,270 participants. Urine chemistry and FOB tests were evaluated three times, while urine sediment examination by photography was evaluated one time. Urine chemistry tests consisted of pH, protein, glucose, ketone, bilirubin, blood, urobilinogen, nitrite, leukocyte, and specific gravity (SG). The urine chemistry test results showed accuracy rates ＞95%, while those of the SG test by using a refractometer had accuracy rates ＜95%. In the FOB quality test, the Bio Focus reagent (BIO FOCUS Co., Korea) disclosed low positive rates (87%). The result of the FOB quantity test showed different values according to the instruments used, and the Kyowa instrument (Kyowa Chemical Industry Co., Japan) revealed the lowest values. In a urinary sediment examination, it is necessary to increase the frequency of the quality assessment trials due to low accuracy rates.
