Prenatal paternity testing is a safe way to determine the biological father of a baby before it is born. This innovative technique can be performed as early as 7 weeks after conception (or 9 weeks after the last period). And AlphaBiolabs can perform this non-invasive prenatal paternity test in Warrington.

The test works by analysing three DNA samples: the baby’s DNA that is found within the mother’s bloodstream, the mother’s DNA and the alleged father’s DNA.

Previously, to get a sample of an unborn baby’s DNA, procedures such as amniocentesis and chorionic villus sampling would have been used. These are both invasive methods and therefore incur a slight risk of miscarriage. AlphaBiolabs’ prenatal DNA test does not carry such risks and there is no harm to the unborn child. The mother needs to provide a blood sample (usually from her arm) and the alleged father’s sample simply involves using a mouth swab to collect DNA from his cheek cells.

Sample collection options in Warrington

There are three sample collection options for prenatal paternity tests in Warrington.

  • The blood and mouth swab samples can be collected at our Walk in Centre in Warrington.
  • We can arrange for one of our highly trained sample collectors to come to your house, your place of work, or anywhere else convenient to collect your samples.
  • We can send you a testing kit and you can arrange your own blood sample collection from a phlebotomist, GP or other medical professional. The mouth swab from the alleged father does not need to be collected at the same location, but it should be collected around the same time to avoid any delays and the risk of the blood sample haemolysing.

How does prenatal paternity testing work?

Once your samples are received at our Warrington laboratory*, the testing process can begin.

Because a baby inherits DNA from both of its parents, the prenatal paternity test analyses the three DNA samples to identify which half of the DNA is inherited from the mother and which half is from the father. If the man is indeed the biological father, both baby and father will share DNA.
