What is the main difference between home and legal tests?
The primary distinction between an at home paternity kit and a legal paternity test uk is not the scientific accuracy of the result, it is the chain of custody.
Both tests utilize the same high-tech laboratory processes and deliver the same degree of accuracy, typically 99.99% or higher for a positive match. However, the way the samples are collected determines how the results can be used.
- At Home Paternity Kit: Also known as a peace of mind dna test, this is for your personal information only. You collect the samples yourself. Because there is no third-party verification of who is providing the DNA, these results are not admissible in court.
- Legal Paternity Test UK: This requires a strict chain of custody. A neutral third party (a professional sampler) must verify the identities of all participants and oversee the collection. This makes the results legally binding for matters like child maintenance, inheritance, or changing a birth certificate.
How does an at home paternity kit work?
An at home paternity kit is designed for convenience and privacy. It is the most common choice for families who want to resolve doubts quickly and quietly without involving external authorities.
Follow these steps to complete your home test:
- Order your kit online through our products page.
- Receive the package in a plain, discreet envelope with no mention of DNA testing on the outside.
- Collect the samples using the provided oral swabs. Rub the inside of the cheek for about 30 seconds to collect epithelial cells.
- Register your samples and send them back to our UK-accredited lab using the provided return packaging.
- Receive results via a secure email. At Brashan DNA Services, we offer same-day results once the samples reach our laboratory.

When should you choose a legal paternity test?
You must opt for a legal paternity test uk if you intend to use the results for any official or judicial purpose. A "peace of mind" test will be rejected by government bodies and courts.
Choose a legal test for the following scenarios:
- Child Maintenance Service (CMS) disputes: To prove or disprove parentage for financial support.
- Changing a Birth Certificate: Adding or removing a father's name at the General Register Office.
- Immigration DNA testing uk: When the Home Office requires proof of a biological relationship for visa or citizenship applications. You can learn more about this on our immigration testing page.
- Inheritance Claims: Proving biological lineage to settle an estate.
- Family Court Proceedings: For custody or visitation rights.
For legal tests, we strongly advise booking a professional collection appointment. Call us at +442046204341 to arrange a certified sampler near you.
Are the results 100% accurate?
While "100% accurate" is a common phrase, in the scientific world of DNA, we provide a probability of paternity. If the man tested is the biological father, the result will show a probability of 99.99% or greater. If he is not the father, the result will be 0%.
For a deeper dive into the science, read our article on whether paternity results are 100% accurate. We use a UK-accredited lab to ensure every sample is processed under the highest quality standards, eliminating the risk of laboratory error.

Can you take a DNA test while pregnant?
Yes, you do not have to wait until the baby is born to find answers. We provide a non invasive prenatal paternity test (NIPP) which can be performed as early as seven weeks into the pregnancy.
How the prenatal dna test works:
- Simple blood draw: The mother provides a standard blood sample.
- Cheek swab: The alleged father provides a simple cheek swab.
- Fetal DNA analysis: Our lab extracts the baby's cell-free DNA from the mother's bloodstream and compares it to the father's DNA.
- Safety: This method is entirely non-invasive and poses zero risk to the pregnancy, unlike older methods like amniocentesis.
For more details on the safety and procedure, check out our guide on taking a DNA test while pregnant.
What if the father is unavailable for testing?
In situations where the alleged father is deceased, missing, or unwilling to participate, we offer alternative dna testing services to establish paternity indirectly. These include:
- Sibling DNA test: Comparing the DNA of two potential siblings to see if they share one or both parents.
- Grandparent DNA test: Testing the parents of the alleged father to determine the likelihood of a biological link to the child.
- Avuncular (Aunt/Uncle) testing: Testing the alleged father's full-blood siblings.
These tests are complex and require sophisticated statistical analysis. We recommend calling us at +442046204341 to discuss which relationship test is most suitable for your specific family tree.

How much does a paternity test cost in the UK?
The cost varies depending on the type of test and the speed of results required.
- At home paternity kits are the most budget-friendly, starting at the price of the kit plus lab fees.
- Legal tests carry a higher fee due to the professional collection and administrative requirements for the chain of custody.
- Prenatal testing is a premium service due to the advanced technology required to isolate fetal DNA from the mother’s blood.
