| Popis: | The cytology laboratory has traditionally performed a relatively small variety of tests. The testing processes employed were generally manually performed and included preparation of glass slide materials, staining of these slides, coverslipping, and microscopic evaluation of the cellular material. Instrumentation in the cytology laboratory was very limited and included a centrifuge, membrane filtration system, and possibly an automated staining machine. If instruments were added, for example, a liquid based preparation device or an automated coverslipping device; the instruments were rarely checked to assure they were operating properly before implementation into clinical practice. In addition, little documentation was maintained with regards to the instrument performance evaluation process. Increasing automation and expansion of testing options have changed how cytopathology is practiced. There are many new devices employed for the preparation of specimens, staining and coverslipping of slides, and evaluation of cellular material. The increasing use of molecular testing methods in cytopathology further adds to the changing landscape of cytopathology. New instrumentation and testing methods are routinely being introduced and the cytopathology laboratory must assure that the testing performed is accurate and consistent. Cytopathology laboratory professionals need to appreciate the value of validation of the tests we perform and the instruments we use in order to best serve the patient. Our clinical laboratory colleagues have traditionally performed validation on both instruments and test methods before using them for clinical testing. If cytopathology wants to perform the complex testing being introduced and effectively utilize new instrumentation, we need to understand the value of validation and how we apply validation to our laboratory practice.
