Non-invasive Prenatal Paternity Test (Steps)
The prenatal paternity tests (CVS and amniocentesis) are invasive and carry with their use a small but significant chance of miscarriage. Chorionic Villus Sampling (CVS) is collecting the chorionic villi that make up the placenta, which is guided by an ultrasound, an OB-GYN uses a catheter through the vagina or a long, hollow needle through the belly (depending on the status of the fetus) to collect cells. That can be done during weeks 10-13 of pregnancy. Amniocentesis collects the amniotic fluid that surrounds the fetus, which is also guided by an ultrasound, an OB-GYN use of a long needle through the abdomen to collect fluid. And this test can be performed during weeks 14-20 of pregnancy.
The discovery of the occurrence of fetal cells in maternal blood has offered a non-invasive prenatal diagnosis as well. By analyzing deoxyribonucleic acid (DNA) profiles, which is material present in nearly all living organisms as the main constituent of chromosomes, the laboratory can compare a fetal DNA profile with genetic DNA samples of the mother and fathers. These small fragments of fetal-derived DNA along with cell-free maternally derived DNA can be counted and quantified. This test can be done as early as the 8th week of pregnancy.
We provide you with a complimentary package sent via FedEx within two business days which will include everything needed to collect the blood sample. We provide within it blood sample collection kit for the mother, two pieces of cotton tipped buccal swabs for the potential father, forms, client information, payment methods, consent forms and a return courier. Also, we will arrange your blood collection at a clinic nearby. Once you decide to go with our services, both samples are then sent to the lab summary. The test examines free-floating fetal DNA from the mother’s plasma and associates it to the mother’s own DNA profile. Once the fetus’s profile is prepared, that profile is then matched to the potential father’s, and paternity can be established. DNA analysis from fetal cells in maternal blood examples is a screening test that is a non-invasive prenatal method and poses no risks to the mother or the fetus.
