Abstract
|
|
|
|
Three external quality assesment trials which composed of 16 control materials (12 chemical materials and four microscopic photographs of urinary sediment) for interlaboratory quality control assesment in urinalysis were performed with 638, 645, and 662 participants, in each, in the year of 2007. The response rate were 95.5% (638/668), 96.7% (645/667) and 97.1% (662/682), in the first, the second and the third trials, in each. The test items include pH, glucose, protein, ketone, bilirubin, blood, urobilinogen, nitrite, leukocyte esterase, specific gravity and four microscopic photographs of body fluid and urinary sediment. The survey results are summarized as follows: 1. The chemical quality control test in urinalysis revealed generally good concordance. 2. The percentage of using urinalysis analyzer was slightly increased as 87.5% and the distribution of using reagent strip was similar to the previous year. 3. The percentage of response rate of microscopic photographs of urinary sediment was 80.7% (536/662) and the percentage of good performance of these tests was 60.6% to 99.1%.
