Invasive prenatal diagnosis of fetal thalassemia. Prenatal Diagnostic Center, Guangzhou Women and Children Medical Center Affiliated to Guangzhou

Alpha thalassemia is a blood disorder in which the body has a problem producing alpha If both parents are carriers, they can pass the disease to their kids. This almost always leads to a fetus dying before delivery or a newborn b

Antenatal screening is effective and simple, and accurate genetic prenatal diagnosis can be achieved in early gestation. Less invasive methods are feasible with ultrasound fetal assessment for alpha-thalassaemia, analysis of circulating fetal nucleic acid in maternal plasma, and pre-implantation genetic diagnosis. Abstract. The responsibility of the obstetrician is to identify during the first trimester women who are carriers for thalassemia. When she has been identified, the father of the baby should be screened and if he is also a carrier, the couple should be offered prenatal diagnosis.
