Each clinical laboratory follows its own logic in deciding how to deploy automated analyzers for
urinalysis, I believe. For instance, all the specimens for which urine sediment microscopy is requested may be first tested using an analyzer, only specimens that are positive in test strip tests subjected to testing by the analyzer, or all samples coming from Urology departments examined by manual microscopy because analyzers could miss cancers. In this context, missing of clinically important signs would become less frequent as we set more stringent conditions for the deployment of analyzers. However, this would reduce the labor saving that comes from the use of automated
analyzers. Here, the appropriateness of the logic used for deploying analyzers becomes a major consideration.
