Background: Laboratory costs are one of the fastest growing areas of health care cost. Not only the developments in education and technology cause a natural increase in the test requests but also unnecessary tests are known to have an important role in the increase in laboratory use. Aim of the study: The aim of study was to determine unnecessary repeated total prostate specific antigen (tPSA) according to minimum retest interval and to evaluate the change between consecutive measurement results with RCV. Methods: According to report of Association for Clinical Biochemistry and Laboratory Medicine, when first result is raised, it is recommended to repeat tPSA once in 6 weeks to assess the trend. In March 2015-2017, tPSA of patients were evaluated. If tPSA was >2.5 ng/mL and this test was repeated in less than 6 weeks, it was determined as unnecessary repeated test. RCV was calculat..
