What is genetic prenatal testing?

genetic prenatal testing concerns undergoing medical procedure that examines deoxyribonucleic acid (DNA) on any genetic abnormalities that could cause a congenital defect or inherited disorder. Although different procedures can detect different disorders, some disorders that genetic prenatal test screens include Down syndrome and bifida spina. Two types of genetic prenatal testing procedures are amniocentesis and sampling of chorionic lips (CVS).

Amniocentesis is the safest to carry out about 15 and 20 weeks of pregnancy. The doctor uses the needle to collect an amniotic fluid sample surrounding the unborn child and tests the cells found in this fluid for any abnormalities. With amniocentesis, these are some risks such as a small chance of abortion.

CVS is carried out earlier than amniocentesis, approximately between 10 and 13 weeks of pregnancy. For this procedure, the physician collects the tissue sample for the placentte to test cells. DOktor can use the use of a catheter or needle to load this sample. Like amniocentesis, CVS comes with a risk of risks, including a higher chance of abortion.

With risks associated with the undergoing genetic prenatal testing, there are many reasons why the doctor could recommend this procedure. For example, one or both parents may have a family history of inherited disorders. Or maybe they will have a child with an inherited disorder like Down's syndrome. Another reason for the test is whether the expectant mother is 35 years or older; This is because at this age the child has a greater risk of having a problem with chromosome.

While the doctor can recommend genetic prenatal testing, the choice is eventually belonged to the mother. During genetic counseling, which often precedes genetic prenatal testing, the advisory helps. Together the counselors and mother could discuss topics such as an importantWater of the procedure, as well as the risks and advantages of the procedure. In addition, they can discuss the possibilities that the mother has if the test shows positive results for genetic abnormality.

It is important to know that although genetic prenatal testing potentially detects abnormalities, positive results do not necessarily guarantee that the unborn child will have a specific disorder. Instead, this could mean that the child has a greater risk of disorder. The opposite is equally true: negative results do not guarantee that the unborn child does not develop or have inherited disorder.
