To check the blood routine, you need to register with the hematology department, because hematology is a specialized department that specializes in diagnosing and treating various blood system diseases, and hematologists are able to make timely diagnosis and treatment of blood system diseases. For example, if a patient has significant microcytic hypochromic anemia, but the patient’s average hemoglobin concentration is not decreased, in this case, it is likely to be thalassemia. By taking the patient’s history and performing relevant tests such as hemoglobin electrophoresis and genetic testing for thalassemia, the diagnosis of which type of thalassemia is present can be confirmed. If there is a blood test or a hematologic disorder, you will need to register with the hematology department.
