Prenatal Diagnosis: The concept of prenatal diagnosis for thalassemia was originated in 1970s when the fetal blood was obtained through aspiration and the globin chain synthesis was performed. After that, the technology has taken a leap forward and through sophisticated DNA analysis, the prenatal diagnosis has significantly improved. •Prenatal diagnosis is ONLY solution to prevent thalassemia major in the high prevalence area •Determination of chorionicity should be done in first trimester of twin pregnancy •Identification of affected fetus should be correctly confirmed before selective termination •Patient and family’s decision bases on an adequate counseling Couples at risk for alpha thalassemia in pregnancy have the option to pursue prenatal diagnosis to determine whether their fetus has ATM. Prenatal diagnosis for ATM is usually done either by chorionic villus sampling (CVS), performed between 10 weeks and 14 weeks of gestation, or by amniocentesis, performed after 16 weeks gestation. Thalassaemia is often detected during pregnancy or soon after birth.

Thalassemia is a group of inherited blood disorders that can affect hemoglobin production and cause anemia. It includes alpha thalassemia and beta thalassemia. Learn about lab tests used to help diagnose thalassemia.

Thalassemia is an inherited disease, therefore if either you or your partner or both have thalassemia; there is a great possibility that your unborn baby may have it too. In case if a single parent is a defective gene carrier, the chances of the unborn baby getting this gene are one in two.

Most babies with alpha thalassemia major do not make it up to the pregnancy or birth.

How is alpha thalassemia treated? Treatment is based on the type and severity of alpha thalassemia. People who are carriers of alpha thalassemia or have alpha thalassemia trait usually have mild or no symptoms and need little or no Prenatal testing consists of prenatal screening and prenatal diagnosis, which are aspects of prenatal care that focus on detecting problems with the pregnancy as early as possible. These may be anatomic and physiologic problems with the health of the zygote , embryo , or fetus , either before gestation even starts (as in preimplantation genetic diagnosis ) or as early in gestation as practicable.

homozygous 3-thalassemia. Although further experience will be needed to distinguish the homozygous and heterozygous states reliably, it now appears that the /-thalassemia gene is expressed in the first trimester. Therefore these data suggest that the antenatal diagnosis of 3-thalassemia is becoming an attainable goal.

Having a thalassemia trait means that you may not have any symptoms, but you might pass that trait on to your children and increase their risk for having thalassemia. Sometimes, thalassemias have other names, like Constant Spring, Cooley’s Anemia, or hemoglobin Bart hydrops fetalis.
