Prenatal Paternity Test
At Hummingbird DNA ®,
we offer prenatal paternity tests.
[A-prenatal-paternity-test] determines who the biological father is of a child prior to when the child is still unborn. Just like with standard paternity tests, a [prenatal-paternity-test] compares the DNA of a child with an alleged father's DNA to see whether there is a match. There are two main methods of prenatal paternity testing that we use. They include amniocentesis and chorionic villus sampling. Both of these procedures for prenatal paternity testing take samples of fetal tissue or fluid which contain the genetic material of the baby, which are then used for DNA testing
and compared with the alleged father's DNA.
Amniocentesis is a prenatal - paternity -test that we perform during the second trimester of pregnancy, at 14 to 20 weeks. During the procedure we use a fetal ultrasound to assess the position of the fetus. The ultrasound guides the insertion of a long thin needle through the mother's abdomen and into the uterus. The needle is inserted carefully without touching the fetus. The needle we insert collects amniotic fluid, about the amount of two tablespoons. The amniotic fluid contains the same genetic material of the baby, and we then use the sample of amniotic fluid for DNA testing.
The other procedure we use as a parental - paternity - test is chorionic villus sampling. Chorionic villus sampling is a test that we perform during the earlier stages of a pregnancy, at 10 to 13 weeks – usually within the first trimester. Chorionic villi refer to small finger-like segments of tissue that are from the placenta and are attached to the uterus wall. The chorionic villi contain the same genetic material found in the baby's cells, and so a sample is taken for DNA testing. With the chorionic villus sampling procedure we perform, we use an ultrasound to guide the insertion of a fine tube into the vagina, though the cervix and into the placenta to collect a small sample of chorionic villi. The other method of performing chorionic villus sampling is by inserting a thin needle through the mother's abdomen, using an ultrasound, and passing the needle into the placenta to attain a sample of chorionic villus.
Samples that we take by a [parental - paternity - test], whether it is amniotic fluid via amniocentesis or chorionic villus via chorionic villus sampling, are used for DNA testing. The samples contain the DNA material of the fetus, and we use these samples to compare with the alleged father's DNA to determine whether there is a match. In doing so, we can identify the child's father or an alleged father can be excluded. We usually make the results of prenatal paternal tests available within five working days.Prenatal paternity tests
are an important tool we provide at Hummingbird DNA®
to answer any paternity questions you may have, which can identify and provide conclusive proof as to who the father of a child is. Paternity tests can be recommended to be conducted early, and the prenatal testing we offer enables a means to determine the father of a child early on while the mother is pregnant and the child is yet to be born.
