Frequently Asked Questions

About our Grandparent DNA Test

For $249, including your test kit and all lab fees, our Grandparent DNA Test can establish a biological connection between an individual and one or both possible grandparents, with results in just 3 business days.

This test is often used when a child’s possible father is not available for paternity testing, or when the child’s grandparents are concerned about their true relationship to their possible grandchild.

In a grandparent test, a DNA profile for each individual taking part in the test is produced. Since a child inherits half of their 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.

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 DNA markers that are shared between the tested parties could be extremely common within the relevant population.

AlphaBiolabs utilizes cutting-edge DNA technology to perform grandparent testing. We analyze up to 42 DNA markers for a fast, reliable result.

Our test results are accurate, but you may not get a conclusive result

AlphaBiolabs' Grandparent DNA Test is extremely accurate. However, due to the nature of grandparent DNA testing, you may not get a conclusive result.

Grandparent DNA testing can be up to 40% inconclusive. We have worked hard to reduce that rate to just 28% for an AlphaBiolabs Grandparent DNA Test. This means that one in four people will not get a decisive answer.

This test comes with a money-back guarantee. If we can't give you a conclusive result, we will refund the price of your test.

Can kits be sent to two addresses?

Yes, AlphaBiolabs can mail your Grandparents DNA Test kits to two different addresses.

You will find the option to list a 2nd address when you check out.

Both test kits will be sent out in plain packaging, for full confidentiality. 

What is peace of mind testing?

At AlphaBiolabs, we offer peace of mind testing with all our DNA testing kits.

As the name suggests, a peace of mind DNA test is for personal use only.  

The results of these tests can give you the answers you need, but they cannot be used for legal purposes or in court proceedings.

Peace of mind tests also allow you to collect your samples quickly and easily at home, without the need to use a more costly and time-consuming third-party to verify the DNA sample collection.

Our money-back guarantee

AlphaBiolabs guarantees that we will produce the most accurate results possible from your DNA test samples.

In the rare case that we cannot provide a result with the samples provided, we will either send a new kit and re-test at no cost to you, or offer a 100% no-hassle refund.
