The genetic test for thalassemia is a blood test that reveals whether a person carries the gene for thalassemia in his or her body. In clinical practice, there are two types of thalassemia, alpha-thalassemia and beta-thalassemia, and the specific genes responsible for the development of the disease are distinctly different. In general, there are 6 types of genetic alterations common to α-thalassemia and 16 types of genetic mutations common to β-thalassemia, and the detection of these genetic mutations can reveal whether a person carries the gene for thalassemia, and it can also make a clear judgment of the severity of thalassemia based on the detection of the gene for thalassemia. Therefore, the thalassemia gene test is the most standard diagnostic method to confirm the diagnosis of thalassemia, and the test results can be available within 5-7 working days through 3 blood tests.
