Two External quality assesment trials which composed of eight control materials(eight chemical materials) for interlaboratory quality control assesment in urinalysis were performed with 456 participants in the year of 2000. The response rates were 83.9% and 80.2% in the first and the second 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 77.6% and the distribution of using reagent strip was similar as last year.
