Non-invasive Prenatal Paternity Test (NIPPT)

What is it?

An Non-invasive Prenatal Paternity Test (NIPPT) can be performed as early as 7 weeks into pregnancy and is used to determine the identity of a child’s biological father while the mother is still pregnant.

The test is 100% risk free for mother and baby, with only cheek swabs required from the alleged father, plus cheek swabs and a blood sample from the mother.

The prenatal paternity testing uses a state-of-the-art process that combines the latest DNA technology and unique methods of preserving the baby’s DNA, which is naturally found in the mother’s bloodstream from 7 weeks into pregnancy.

If the tested man is the father of the baby, both will share enough matching DNA markers in their genetic profiles to verify a biological relationship.

Why is this test useful?

Determining the biological father of the child during pregnancy can help people plan and make important decisions before the baby is born.


The prenatal paternity test results are 100% accurate and reliable based on the samples received at AlphaBiolabs laboratory.

AlphaBiolabs is the only UK DNA testing laboratory to hold ISO 17025 accreditation for non-invasive prenatal paternity (NIPP) testing.

We have invested in the very latest technology for our state-of-the-art laboratory, using the most up-to-date scientific processes to ensure the best possible customer experience, and rapid results every time.

Samples required

  • The test requires:
  • Two cheek swab samples from the alleged father
  • Two cheek swab samples from the mother
  • A blood sample from the mother – this must be collected by a trained nurse, a phlebotomist or a fully-trained AlphaBiolabs sample collector.

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

How does the test work?

Once the mother’s and alleged father’s samples have been received at the laboratory, DNA is extracted from both samples.

AlphaBiolabs in-house geneticists uses the very latest scientific techniques to ensure the baby’s DNA can be identified within the mother’s blood sample.

Every person inherits half of their DNA from their mother and half from their father. Provided there is sufficient foetal DNA within the mother’s blood sample to extract the baby’s DNA profile, our scientists will compare the DNA profiles of the alleged father and the baby to identify matching DNA markers.

If the tested man is the biological father of the baby, both will share enough matching DNA markers to verify a biological relationship.

If the tested man is not the biological father, there will be significant differences between the DNA of the man and the baby.

The results of the test will show the probability of paternity for the alleged father in relation to the unborn child.

If the tested man is the father of the baby…

• Both will share enough matching DNA markers to verify a biological relationship

If the tested man is not the father of the baby…

• There will be significant differences in the DNA profiles of the man and the baby

In the unlikely event of an inconclusive result, we will offer an additional test free of charge with a newly collected sample, as long as it is conducted at least two weeks after the first test.

If this second test is also inconclusive, we will perform a third and final test, also free of charge, after at least another two weeks.

This is to allow sufficient time for the foetal DNA to increase as the pregnancy progresses.

Please note that the customer will still be responsible for the cost of repeat blood sample collections.

In approximately 3-5% of cases, foetal DNA never reaches a sufficient level for successful testing.

If a conclusion cannot be reached after we have performed three tests, AlphaBiolabs will refund the cost of the prenatal paternity test.
