DNA Testing

Twin DNA Testing

Twin testing, also known as Zygosity testing, will establish if twins are identical or not. The test is available as an appointment at one of our DNA Clinics. Or you can order a Twin DNA test kit by calling 0800988 7107. Also, the twin DNA test is only available as a ‘peace of mind’ or test.

How does a Twin DNA Test work?

Twins can either be identical or fraternal twins. The Twin DNA test can prove whether you, or your children, are identical or fraternal twins. The DNA of identical twins is exactly same. As a result, they will have identical DNA profiles.

The DNA profiles of fraternal twins can be as different as the profiles of any two siblings that are not twins. In other words, they only share half of their genes in common like other siblings.

By comparing the DNA profiles of each twin, we can determine if twins are identical or fraternal.

Frequently Asked Questions

How long does it take for the Twin DNA test results?

The average analysis time in the lab is around three to four working days. But this does not include the quality checks needed for sample integrity or your consent paperwork. So, from receipt of your samples at Crystal Health Group, it takes on average of about three to five working days. If there are any unforeseen delays, for example, such as the paperwork we receive not being quite right, we will contact you as soon as possible to let you know.

How do I order a Twin DNA Test?

Here are the options available to you:

Call 0800 988 7107 to make an appointment at a DNA Clinic or order a *DNA self-collection Home Kit
Call 0800 988 7107 to arrange a home visit from a sample collection officer

* Please note, you can only use self-collection kits for peace of mind purposes only. This test cannot be used for legal purposes.

How accurate is the Twin DNA Test?

The Twin DNA test provides answers to the following questions:

Are my twins identical or non-identical?
Am I an identical or non-identical twin?

We can determine the above because identical twins will have identical DNA profiles.
