How we do our DNA testing

We use state-of-the-art DNA technology to ensure the reliability and accuracy of our genetic testing.

Our Y chromosome test kit includes mouth swabs to be rubbed gently and painlessly on the inside of the cheek. No blood is required. 

About the Y chromosome test

All male children inherit their Y chromosome from their father. When these children become fathers, they will in turn pass the Y chromosome inherited from their father to their children. A Y chromosome test (Y-STR test) is therefore used in cases where alleged male relatives wish to confirm they share a common paternal line.

Males coming from the same paternal line will always share the same Y chromosome. The low mutation rate of the Y chromosome also makes this test more reliable.

As the Y chromosome is only found in males, females cannot directly carry out a Y chromosome test. However, if needed, they could ask a male, paternal biological relative to take the test on their behalf.

When would a Y chromosome test be needed?

A Y chromosome test compares the Y chromosome profiles of the tested males to help confirm whether they share a common paternal lineage.

If the males have different Y chromosome profiles they do not share the same paternal line. A full match confirms a shared paternal line.

The Y chromosome test can also be used by male cousins who want to see if their fathers were brothers or to check if they share a common ancestor.

Please note: this Y chromosome test if for peace of mind only, and cannot be used for legal matters or in court. If you require a Y chromosome test for legal reasons, such as for immigration cases where proof of a biological relationship is needed, you will need a legal DNA test.
