As reported by several news sources and WebMD, another study has validated the use of fetal DNA circulating in the mother’s blood for a paternity test. Known as non-invasive prenatal paternity testing, the test allows women to undergo a paternity test before the baby is born, while eliminating the need for an amniocentesis or chorionic villus sampling—procedures which carry a risk for miscarriage.
The authors of the study tested the procedure on 30 pregnant women who were between 8 and 14 weeks in their pregnancy. They collected blood samples, separated the fetal DNA in the mother’s blood, and compared it with blood collected from the biological father along with blood from 29 other unrelated men. In each case, the biological father was correctly determined by the procedure.
DDC has offered the non-invasive prenatal paternity test since August of last year. For more information, visit our prenatal DNA testing page, which features a video explaining the process. You can also call 1-800-613-5768 for a free consultation.
