AlphaBiolabs’ prenatal DNA test can accurately determine the paternity of a baby before it is born. An accurate gender test can also be requested at the same time.

The test is non-invasive, which means there is no risk of miscarriage and it is totally safe to the mother and the unborn child. As such, a prenatal paternity test can give you peace of mind long before the baby is born.

Because a baby inherits DNA from both of its parents, this prenatal paternity test can identify if a man is the father of a baby by looking at samples containing:

  • the man’s DNA
  • the pregnant woman’s DNA, and
  • the unborn baby’s DNA

The prenatal paternity test can be taken after the seventh week of pregnancy (5 weeks after conception). A blood sample is needed from the mother and two cheek swabs from the alleged father. The mouth swabs collect cells from the inside of his cheek and is a completely painless way of providing a sample of DNA for testing.

The advanced procedure works by preserving and analysing the baby’s DNA that is found within the mother’s bloodstream. This can be achieved because the baby’s cell-free foetal DNA transfers through the placenta to the mother’s blood. The mother’s blood sample must be collected by a medical professional, such as a nurse or a phlebotomist. The blood sample is then sent to our laboratory for testing as soon as possible to avoid the breakdown of red blood cells.

We provide at least 99.9% probability of paternity where the father is confirmed as being the father.

Please note that in approximately 3–5% of cases, foetal DNA never reaches a sufficient level for successful testing. Should this happen after three attempted prenatal paternity tests, AlphaBiolabs will refund the cost of your prenatal paternity test. You can read more about our money-back guarantee on our website.
