Methods for Pre-Natal DNA Tests

When to have a Prenatal DNA Test done?

Whether you can have a Prenatal DNA test done during your pregnancy depends on the method and time you choose for the DNA test. Prenatal paternity tests require a little more attention and care than having the paternity test after the baby is born.

The two methods recommended by most of the doctors for Prenatal DNA tests are Amniocentesis or CVS. Amniocentesis involves taking a sampling of the amniotic fluid surrounding an unborn fetus. Amniocentesis can be performed during the 14th to 24th week of pregnancy, meaning the second trimester. On the other hand, CVS includes taking a portion of the placenta in the first trimester of pregnancy.

Both these methods of prenatal genetic testing have their inherent risks and these should be considered when deciding to have Prenatal DNA Testing done or which method to use. To know more about DNA Testing services, please visit the site http://www.oqps.ie
