Book Your Zygosity Test

Order a quick and easy Zygosity Test from just £95

This DNA Zygosity Test is to determine whether multiple children from the same birth, such as twins, triplets and so on are genetically identical or not.

When you book this Zygosity Test a DNA Testing Kit will be shipped in plain packaging to your address. If you are outside of the UK shipping charges may apply, these will be calculated at Checkout.

Who needs to take a test?

All children involved in the multiple birth will need to provide a DNA sample.

If there are several people involved in the multiple birth but not all can provide a DNA sample we will only be able to provide the relationship between those samples provided.

Please tell us the total number of people taking part in the test by selecting the appropriate drop-down box at the bottom of this page when submitting your booking.

How is the test taken?

DNA samples are taken by simply rubbing a test swab a few times on the inside of the cheek. This process collects a small sample of cells which is all we need to extract the DNA and run the Zygosity Test.

A sterilised test swab for each of the people involved in the test is included in the DNA Testing Kit.

Where do we go to take the test?

You don’t need to go anywhere, you can collect the DNA samples required for the test in the privacy of your own home.

How many DNA Testing Kits do I need?

One DNA Testing Kit includes everything you need for everyone providing a DNA sample at the same address. You would only need an additional DNA Testing Kit if one or more of the people providing a DNA sample live at a different address.

What if we don't live in the same household?

If one or more of the people providing a DNA sample live at another address in the UK or in a different country we can send a DNA Testing Kit to their address as well.

If this applies to you choose the appropriate selection from the ‘Delivery instructions’ below and let us know how many people are at the second address in the ‘Test Individuals at this Address’ dropdown so we can send the appropriate number of test swabs.

If you have more than two additional shipping destinations please contact our friendly customer liaison team to arrange this.

How do I send the samples back?

Put the form and all the samples in the tamper proof bag supplied, seal and return to NorthGene.
