<p>Zinc deficiency causes a wide variety of pathologies, including taste disorders, immunological disorders and exacerbation of various diseases, which can be corrected by adequate zinc supplementation. Therefore, it is important to measure serum zinc levels correctly and promptly and to control the serum zinc level. Our hospital has been testing for serum zinc levels since July 2019. The aim of this study was to evaluate the effect of changing from external to in-hospital serum zinc tests. The study included 4,722 patients whose serum zinc levels were measured at our hospital between January 2019 and February 2020. We compared the situation before and after the introduction of the test in the hospital, which increased the number of patients (both inpatients and outpatients) tested. In inpatients, there were no significant differences in serum zinc levels and prescribed doses of Nobelzin between the time before the introduction of the test and that after the introduction. However, in outpatients, serum zinc levels were lower, and the prescribed dose of Nobelzin was also predominantly lower. This could be attributed to the fact that the serum zinc level can be determined on the day of outpatient treatment by the in-hospital tests, which enabled us to adjust the prescribed dosage of Nobelzin. These results suggest that the in-hospital serum zinc tests will assist physicians in their practice and contribute to reducing the burden on patients.</p>
