Abstract
Laboratory tests are useful for improving diagnostic efficiency. Furthermore, they are essential for carrying out medical treatment. However, the environment surrounding the clinical laboratory is becoming increasingly severe, and laboratory testing is falling into a dangerous situation. Under these circumstances, unnecessary laboratory tests have been conducted without considering the prescribed limits. At our hospital, requests for laboratory tests are made using the electronic medical records. However, there have been occurrences of multiple tests exceeding the stipulated limits of the number of tests conducted on the same day for one patient, the number of tests conducted simultaneously, and the number of related tests. The introduction of a check function for each laboratory test that would display a warning when multiple tests are requested within a certain period of time would reduce the number of unnecessary laboratory tests.
