Summary
Background. The increasing availability of automated analyzers capable of evaluating the corpuscular fraction of urine, together with the use of automated dip-stick analysis and the possibility of dosing the urine analytes in liquid chemical, has focused the interest of laboratory professionals (doctors, technicians and graduates) on chemical and morphological urinalysis (CMU). Methods. During the Urinalysis now 2009 Congress a questionnaire was handed out which contained 20 questions, some of which were multiple choice. Data from 83 questionnaires from 69 different laboratories were evaluated. Results. The great majority of laboratories (93%) follow guidelines which advise that CMU be performed on midstream voided samples of first morning urine. Most laboratories (68%) supplied patients with detailed instructions concerning the collection of the sample and give reasonable attention to the pre-analyticalphase of the CMU. Nearly all laboratories (99%) performed chemical urine examination using dry chemistry analysis by means of automated dip-slide analyzers. In 43 laboratories (62%) analysis of urine particleswas performed by automated analyzers. Conclusions. Data obtained from the questionnaires revealed a great change in our laboratories: more attention to guidelines, massive implementation of automated analyzers also for urine particle analysis and the expression of results in quantitative terms.
