Basics of a prenatal cell-free DNA (cfDNA) screening?
The prenatal cell-free DNA screening is a blood test for a pregnant woman. During the period of a pregnancy, some DNA of the unborn baby circulates in the mother’s bloodstream. This screening is also known as the “noninvasive prenatal screening” because there is no use of surgical instruments. This test is also considered very safe. The cDNA screening is used to check this DNA to find out if the baby is more likely to have any kind of disorder such as Down syndrome or another disorder caused by the trisomy. During the procedure In this screening, a maternal blood sample is taken and then sent to the lab. The lab will analyze the maternal and fetal DNA in the blood sample. A higher than expected ratio of chromosome 21 indicates the increased risk of the disorder such as Trisomy 21 in the fetus, this disorder is the main cause of the Down syndrome. This test is recommended for women who are at least 10 weeks pregnant. Contact Noninvasive prenatalDNA testing Texas professionals who
