Which department should I visit for trace element testing?

You can visit multiple departments for trace element testing, with the specific choice depending on individual circumstances and hospital setup. Generally, you can make an appointment with the nutrition department, where doctors can perform trace element testing to determine whether there is a deficiency in elements such as iron, zinc, or magnesium. General internal medicine, hematology, endocrinology, and general practice departments are also common choices. General internal medicine and general practice departments can provide comprehensive physical examinations, including trace element testing. Hematology departments primarily treat blood-related diseases, such as iron-deficiency anemia, and may require trace element testing. Endocrinology departments focus on endocrine system disorders, such as diabetes, which may affect the metabolism of trace elements. Therefore, you can visit departments related to nutrition, internal medicine, hematology, and endocrinology for trace element testing.
