Thalassemia is the full name of thalassemia. Genetic testing for thalassemia can be done at different times of pregnancy through chorionic villus puncture, amniocentesis, and umbilical cord blood sampling to determine if your child has thalassemia. 1. Chorionic Villus Puncture: Genetic testing for thalassemia can be done by chorionic villus puncture at 10 to 13 weeks after pregnancy. During the procedure, the doctor will extract the chorionic villi from the abdomen or vagina at the site where the placenta is formed to obtain the fetal cells, so as to know the chromosomal and genetic conditions of the fetus. 2. Amniocentesis: At 16 to 21 weeks of pregnancy, amniocentesis can be used to extract amniotic fluid cells and DNA for genetic diagnosis to determine whether the child has a genetic disorder. 3. Umbilical cord blood extraction: After 22 weeks of pregnancy, 0.5 to 1.5 ml of fetal umbilical cord blood can be extracted for genetic testing to diagnose whether the child has thalassemia. After pregnancy, it is recommended to take obstetric checkups on time. If there is any discomfort, it is recommended to consult a doctor in time and under the doctor’s guidance.
