Prenatal Paternity Test

Our non-invasive prenatal DNA testing provides the most accurate way to determine paternity before birth. It uses a state-of-the-art process which combines the latest DNA technology and unique methods of preserving the baby’s DNA, which is naturally found in the mother’s bloodstream after 7 weeks into the pregnancy.

One of the best ways to explain non-invasive is to look at the opposite approach: an invasive DNA paternity test. The traditional invasive prenatal paternity tests require that cells be obtained from either the amniotic fluid or the placenta.

The non-invasive paternity test uses a simple blood sample from the mother and therefore does not require a needle to be inserted into the womb.

Non-invasive prenatal paternity testing can be carried out as early as 7 weeks into the pregnancy. You can use our pregnancy calculator to work out how many weeks pregnant you are.

With our unique, non-invasive prenatal paternity test, there is no risk to the mother or baby.

This is the most advanced prenatal paternity test currently available. We provide at least 99% probability of paternity where the father is confirmed as being the biological father.

Two mouth swabs and a blood sample are needed from the mother, along with two mouth swabs from the alleged father.

Yes. We need samples from both the mother and alleged father.

Our Prenatal Paternity Test is ideally suited for expectant parents who have become pregnant following fertility treatment.

With increasing numbers of babies being born as a result of in vitro fertilisation (IVF) or surrogacy, DNA testing can provide confirmation and peace of mind as to the biological identity of an unborn child’s father.

Although mistakes are rare, as the fertilisation process takes place in a clinic or hospital, there is always a small risk of the wrong sample being used. This means that there is a possibility that the sperm donor may not be the biological father of the child.

A prenatal paternity test can help ensure any errors are identified before the baby is born.

The samples do not need to be collected at the same location. However, the samples should be collected around the same time to avoid any delays and the risk of the mother’s blood sample degrading.

The blood samples are time sensitive and need to be collected by a trained nurse, a phlebotomist, or an AlphaBiolabs fully trained sample collector. The mouth swabs also ideally need to be collected by an AlphaBiolabs sample collector. Both of these samples can be collected at the same time, or separately, at one of our nationwide Walk in Centres.

We can also arrange to have one of our trained sample collectors visit your home, or anywhere else convenient, to collect your samples. These two options ensure that the samples are collected correctly and are then safely returned to our laboratory for testing. Alternatively, you can choose to arrange your own blood sample and mouth swab collections. In this case, you will be responsible for returning the samples to the laboratory.

In the event of an inconclusive result, we offer an additional free of charge test with a newly collected sample, two weeks after the first test.

If this test is also inconclusive, we will perform a third and final test, also free of charge, after another two weeks. Please note that you are still responsible for the cost of all blood sample collections.

In approximately 3-5% of cases, foetal DNA never reaches a sufficient level for successful testing. If this happens after we have performed three tests, AlphaBiolabs promises to refund the cost of your prenatal paternity test (please note this refund will not include the cost of any additional sample collections).

We are the only testing company that offers this money-back guarantee.

Please note if you receive an inconclusive result and decide to cancel your test rather than proceeding with the additional second and third free-of-charge tests, we will be unable to offer a refund.

Results can be made available in 4–6 working days depending on the level of service you choose.
