Özet

Urine may be a waste product, but it contains an enormous amount of information. Well-standardized procedures for collection, transport, sample preparation and analysis should become the basis of an effective diagnostic strategy for urinalysis. As reproducibility of urinalysis has been greatly improved due to recent technological progress, preanalytical requirements of urinalysis have gained importance and have become stricter. Since the patients themselves often sample urine specimens, urinalysis is very susceptible to preanalytical issues. In order to increase the reliability of the test results and to reduce the cost, the precautionary measure and prevention is very important in the preanalytical phase. The laboratory must monitor and evaluate the overall quality of the preanalytic systems and correct identified problems for each specialty and subspecialty of testing performed. The laboratory must establish and follow written policies and procedures for an ongoing mechanism to monitor assess, and when indicated, correct problems identified in the preanalytic systems. The preanalytic systems assessment must include a review of the effectiveness of corrective actions taken to resolve problems, revision of policies and procedures necessary to prevent recurrence of problems, and discussion of preanalytic systems assessment reviews with appropriate staff. The laboratory must document all preanalytic systems assessment activities. An effective diagnostic strategy from urine should be based on standard procedures for collection, transport and analysis. The time of specimen collection must be recorded both on the examination request and on the subsequent report to aid in the correct interpretation of findings.
