The methods of detecting thalassemia mainly include routine blood test, genetic test and hemoglobin electrophoresis. 1. Routine blood test: routine blood test mainly includes red blood cell and hemoglobin test, thalassemia is a kind of microcytic hypochromic anemia. Thalassemia is a kind of microcytic hypochromic anemia. Firstly, we can check the number of red blood cells and hemoglobin indexes through routine blood tests, and make judgment with the help of symptoms and signs. However, the number of red blood cells and hemoglobin are not fixed and have a wide range of variations, so sometimes misdiagnosis may occur. 2. Genetic testing: Genetic testing is a means to diagnose thalassemia. Thalassemia is hereditary, so thalassemia patients have some genetic defects. Thalassemia is an anemia caused by a defect in the gene for the synthesis of pearl protein. Through genetic testing, it can be found out whether it is thalassemia or not, and a diagnosis can be made. 3. Hemoglobin electrophoresis: When thalassemia occurs due to the disorder of bead protein synthesis chain, the number of bead proteins decreases or completely lacks, and the life span of red blood cells is shortened, resulting in anemia. Abnormal hemoglobin can be detected and judged by electrophoresis, which is convenient and time-consuming. There are many ways to check thalassemia, but mainly the above three methods. You can choose the appropriate examination method according to your own reality. Usually pay attention to the adjustment of diet and living habits, appropriate exercise, improve their immunity, specific diagnosis should be carried out under the guidance of physicians.
