The cost of thalassemia screening is usually around $800. Thalassemia is a hereditary disease, due to genetic changes, resulting in disorders in one or more of the hemoglobin peptide chains, eventually causing red blood cell lysis and destruction. Routine blood test, hemoglobin electrophoresis, peptide chain test and thalassemia gene test are available for thalassemia, and hemoglobin electrophoresis test can be used to diagnose thalassemia major and moderate. In addition, the peptide chain test can detect thalassemia caused by alpha peptide chain deletion in mild cases. The most accurate method is the thalassemia gene test, which costs about 800 RMB in total.
