Abstract
-
Three external quality assesment trials which composed of 12 control materials(12 chemical materials) for interlaboratory quality control assesment in urinalysis were performed with 446, participants, in each, in the year of 2003. The response rate were 92.4% (414/448), 91.9% (419/456) and 91.3% (408/447), in the first, the second and the third trials, in each. The test items include pH, glucose, protein, ketone, bilirubin, blood, urobilinogen, nitrite, leukocyte estrase and specific gravity. 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 86.8% and the distribution of using reagent strip was similar to the previous year.
