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 a grandparent DNA 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 is produced for each individual taking part in the test. 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 this inconclusive rate to 23%, meaning that only around one in four people do not get an answer to their question.

This is still not acceptable at AlphaBiolabs and with this in mind we have launched our guaranteed result or your money back promise. For the small number of customers who order a Grandparent DNA Test and do not get a conclusive result, we will refund the price of the test, guaranteed. Please note, all relationship DNA tests bought via third party retailers are not included in this guarantee.

How we do our DNA testing

We utilise the most up-to-date DNA testing technology to ensure the reliability and accuracy of our genetic testing. We also offer the fastest turnaround times in the UK for DNA testing.

The Grandparent DNA Test kit includes mouth swabs to be rubbed gently and painlessly on the inside of the cheek to collect cheek cell DNA, with no needles required.

Our grandparent test looks at up to 42 DNA markers (loci) – double the industry standard for DNA testing – examining the child’s DNA and the alleged grandparent’s DNA to identify matching DNA markers. 

Your test kit will be sent directly to your preferred address in discreet, plain packaging, for full confidentiality.

What’s in our Grandparent DNA Test kit?

Our Grandparent DNA Test kit contains enough collection swabs to test one alleged grandparent, one grandchild and the biological mother, 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. However, this is not essential, and the test can still be performed without the mother’s sample.

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 three 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 (additional charges apply). 

Your test kit will be sent directly to your preferred address in discreet, plain packaging, for full confidentiality.

I haven’t seen my father since I was a child but recently had doubts he was actually my biological father. My grandparents have always been there for me and agreed to have a DNA test to settle all of these doubts once and for all. The thought of having a test was nerve wracking but AlphaBiolabs performed a next day test with no hassle at all. The results were positive meaning that I can move on with my life. Thank you!
