Grandparent DNA testing

Grandparent DNA tests can be used to establish a biological relationship between an individual and one or more of their alleged grandparents.

One of the main reasons why this grandparent test is performed is when a child’s alleged father is unavailable for paternity testing and the child’s grandparents want to know whether the child is truly related to them.

In a grandparent test, a DNA profile for each individual taking part in the test is produced. Since a child inherits half of his or her genetic profile from each biological parent, when one or more of a child’s parents is unavailable for testing, we can look to the grandparents to determine if they contributed DNA to the child’s genetic profile.

DNA grandparent testing is not as conclusive as paternity or maternity analysis and should only be used when it is not possible to perform these other types of testing.

People who are related usually share more genetic markers than people who are unrelated and an inconclusive DNA grandparent test result could be due to a low number of matching DNA markers between the tested individuals. Alternatively, the markers that are shared between the tested parties could be extremely common within the relevant population.

A guaranteed result or your money back

At AlphaBiolabs we understand that the reason you have ordered a DNA test is to get an answer. However, not all tests are conclusive, and therefore you may not get a decisive answer to your question.

It is the industry’s best kept secret that for most laboratories, grandparent testing can be up to 40% inconclusive. This means that four people in every 10 do not get the result they have paid for. At our award-winning DNA laboratory, we have been able to reduce the inconclusive rate down to 23%, meaning that nearly one in four people do not get the answer to their questions.

This is still not acceptable at AlphaBiolabs and with this in mind we have launched our guaranteed result or your money back promise. For every customer ordering this grandparent test and not getting a conclusive result, we will refund the price of your test, guaranteed. Please note, all relationship DNA tests bought via third party retailers are not included in this guarantee.

We send your DNA grandparent test kit direct to an address of your choice using discreet packaging.

Our grandparent test kit includes mouth swabs to be rubbed gently and painlessly on the inside of the cheek, therefore no blood sample is necessary.

Our grandparent tests look at 25 DNA markers and examine the child’s DNA and identify which half is inherited from the grandparents. Now you can find out the answers you need with the UK’s most popular home grandparent test kit from AlphaBiolabs.

What’s in our grandparent DNA testing kit?

Our grandparent DNA testing kit contains enough collection swabs to test one alleged grandparent, one child and one parent if available.

With grandparent testing it is beneficial to also provide a sample from the mother, if possible, to reduce the possibility of an inconclusive result. We do not charge extra to process the mother’s sample.

This applies even if the mother is known to be a biological parent, as a greater probability of a conclusive result for grandparentage can be established with a comparison of the child’s sample against both the grandparents. However, the mother’s sample is not compulsory to perform the grandparent test.

Enclosed in our grandparent DNA test kit:

  • Peace of Mind DNA test request/consent form
  • Full instructions on how to take the grandparent DNA test
  • A self-addressed envelope to send your DNA test samples back to us
  • Three DNA sample collection swab packages containing two swabs in each package
  • Individual DNA test sample envelopes for the alleged grandparent, child and mother (if available)

If you want to test more than four people with the same test, you can add extra people to the package when ordering and more swabs will be provided in the DNA test kit.
