DNA Testing FAQs

DNA testing is an increasingly common way of determining relationships between individuals, such as whether a man is the father of a child. Now available as home kits used for peace of mind DNA tests are also often used in court cases and to prove paternity in maintenance claims. But what exactly do they involve and how accurate are they? Here are some of the most common DNA Testing FAQs:

Q. What is a DNA Test?

DNA – Deoxyribonucleic acid – is a chemical found in most of the cells in the human body and indeed all living organisms. DNA is responsible for storing information which is passed on from generation to generation. It is what determines what colour your eyes are, how tall you are – in fact, everything about your physical appearance and more.

As half of your DNA is passed on by your mother, and half by your father, it can be used to prove paternity and maternity, as well as other relationships.

Because DNA is found in almost every cell, it is present in a person’s saliva, blood, hair and fingernails and these are the samples most commonly used for DNA testing.

Q. How is a DNA test done?

Most DNA tests simply involve testing cheek cells. These cheek cells are collected by rubbing a mouth swab on the inside the cheeks of the person taking part in the test. This buccal swab – like a cotton bud, but bigger – painlessly collects cells from the inside of the mouth, from which DNA is extracted.

The swabs are then sealed in sample collection envelopes and sent off to the laboratory performing the test.

In certain cases, blood samples will be required, but this is not usually the case.

We also offer hair DNA testing and can use samples such as nail clippings, ear wax and semen. Please Contact Us for more information.

Q. Do you need the mother's permission to do a DNA test?

The father can give consent if he is named as the father on the child’s birth certificate, was married to the mother when the child was born or has a court order giving him parental responsibility. If none of these apply, then the mother MUST give consent.

If the father is legally entitled to give consent for the child to be tested, then we do not need a signature from the mother.

It is a criminal offence under the Human Tissue Act to have human tissue with the intention of its DNA being analysed, without the informed consent of the person from whom the tissue came. You can read more on our page about the 2004 Human Tissue Act.

If you are unsure of your ability to provide consent on behalf of a child please seek legal advice or Contact Us for more information before proceeding with a test.

Q. What happens to my DNA samples after you have tested them?

DNA samples used for peace of mind tests are destroyed after results have been issued. Samples used for a court admissible test are retained for 6 months after issuing results before being destroyed.

Q. Are your kits discreet?

All our kits are sent out in plain white envelopes marked Private & Confidential. We do not put our company name or any branding on the outside to ensure absolute discretion.
