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. For your peace of mind, we use the latest 27 marker technology. Our Y chromosome test (also referred to as a Y-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.

What is Y chromosome testing?

A Y chromosome test (Y-STR test), also known as a Y-DNA test, is used in cases where alleged male relatives wish to confirm they share a common paternal line. All male children inherit their Y chromosome from their father; these children will in turn pass the Y chromosome inherited from their father to their children when they become fathers. Since the Y chromosome mutates once every 10,000 years, it is possible to analyse and compare test participants to determine a biological relationship through the paternal family line.

If the males in question are related, their Y chromosome will be identical. The Y chromosome is only found in males. Females do not have Y chromosomes. This means that although females cannot directly carry out a Y chromosome test, they can ask a male, paternal biological relative to take the test on their behalf.

When would Y chromosome testing be needed?

A Y chromosome test can help confirm if individuals share a common paternal lineage. This test will compare the Y chromosome profiles of the tested males. A full match between profiles confirms a shared paternal line. If the males have different Y chromosome profiles then they do not share the same paternal line. Other uses of the Y chromosome test include male cousins who can use this test to see if their fathers were brothers or to check if they shared a common grandfather or ancestor.

If you require a Y chromosome test for legal reasons, such as in immigration cases where proof of a biological relationship is required, you will need a legal DNA test. For further advice call our expert team on 07360904566.
