How early can you do a DNA test on an unborn baby?

A DNA test on an unborn baby can be performed from as early as 7 weeks into the pregnancy. This type of DNA test is called a prenatal paternity test. It is a non-invasive method, which requires a blood sample from the mother and a mouth swab from the alleged father. This novel procedure is ideal if there is uncertainty surrounding the father of the baby. Not only can it be carried out at an early stage of the pregnancy, it is 100% safe to both mother and child.

The test works by analysing the baby’s DNA that is found within the mother’s bloodstream. There is no risk to the mother or the unborn child, unlike an invasive prenatal test in which embryonic fluid is taken directly from the womb using a needle.

How does this early DNA test work?

The mother’s blood sample must be collected by a medical professional, such as a doctor, a nurse or an AlphaBiolabs sample collector. Since blood samples break down quickly, they must be sent for testing as soon as possible after collection. DNA from the alleged father is easily taken using a mouth swab on his inside cheek. It is advised that the samples are collected around the same time to avoid any delays in the testing process.

The prenatal test procedure works by analysing the collected DNA samples to determine an accurate match. Since DNA is inherited from both the mother and the father, a match will exist when the tested man is related to the baby. This can confirm without question the identity of the father. AlphaBiolabs provides at least 99% probability of paternity where the father is confirmed as being the biological father.

The prenatal paternity test costs £875 and can be ordered here. Password-protected results will be available within 7 working days. Should you want to receive the results faster, you can pay an extra £200 to receive the results in 4 working days. To help you pay for this test, a 6-months interest-free credit option is also available upon request.
