Non-invasive DNA testing can detect thalassemia genes.
Thalassemia is one of the common single-gene genetic disorders, and prenatal diagnosis of the fetus is the only way to avoid the birth of a fetus with thalassemia major. Studies have shown that the application of non-invasive prenatal screening techniques can effectively detect some single-gene genetic disorders, including alpha-thalassemia.
Non-invasive prenatal diagnosis of thalassemia refers to the use of non-invasive means to obtain fetal genetic material for genetic testing to determine the type of fetal thalassemia gene mutation, in order to clarify whether to terminate the pregnancy, in which cffDNA as the genetic material used for non-invasive prenatal diagnosis of monogenic thalassemia has a better application prospect, and can effectively reduce the rate of missed diagnosis and misdiagnosis of thalassemia.
Specific tests should be performed under the supervision of a physician.
