During pregnancy, fetal DNA is present in the mother’s blood. Paternity can be determined by sequencing and analyzing cell-free DNA isolated from maternal blood. The test is non-invasive and only requires a sample of the mother’s blood, which is safe for both mother and fetus. Other methods of prenatal DNA testing are invasive and may carry risks such as miscarriage and leakage of amniotic fluid. Our DNA tests are highly technical and the most accurate on the market. Genetic analysis of more than 5,000 traits called single nucleotide polymorphisms (SNPs) determines paternity with 99.9% accuracy. We are also able to perform multiple alleged paternity tests at an additional cost.
Prenatal DNA paternity tests are done for “peace of mind” and are not admissible in court. Most courts require a legally authorized paternity test to prove paternity after a child is born.
How many weeks do I need to get pregnant?
Our non-invasive prenatal paternity tests confirm from the 7th week of pregnancy. However, the best test is after the 10th week of pregnancy. If the sample is provided too early or if the gestational age is estimated incorrectly, the sample will not contain enough fetal DNA and no results will be obtained. Therefore, it is recommended to wait at least 10 weeks. If there is not enough fetal DNA in the sample, we will ask you to take a sample later.
Upon receipt of your request and payment, we will send you the designated package by email. Your kit includes everything you need to collect the samples and return them to us. Take the kit to your local doctor or pathology center for sample collection. Please note that additional costs may be charged by your doctor or pathology center and are not included in the cost of the test.
DNA paternity testing can be done whether the child was born through in vitro fertilization, surrogacy, or twin pregnancy, but the samples required for DNA testing can vary.
