Choosing to take a DNA test is often a life-changing decision. Whether you are looking for clarity regarding a child's parentage, navigating a complex immigration application, or seeking a "peace of mind" answer for your family history, the process can feel overwhelming. At Brashan DNA Services, we understand that uncertainty is a heavy burden. Our goal is to provide the fastest, most accurate dna testing services in the UK to help you move forward.
I’m Erada Oguntoye, CEO of Brashan DNA Services. In my time leading this company, I’ve seen how much stress can be removed simply by having the right information. Here are 10 essential things you should know before booking a paternity test uk.
1. How accurate is a paternity test?
When it comes to DNA, there is very little room for error. A paternity test works by comparing the genetic markers of the child with those of the alleged father. Because a child inherits exactly 50% of their DNA from each biological parent, the laboratory can determine parentage with extreme precision.
If the DNA profiles do not match, the alleged father is excluded as the biological parent with 100% certainty. If the profiles match, the probability of paternity is typically 99.9% or higher. While people often ask why it isn't 100% for a positive result, this is due to statistical calculations used in genetics; however, for all intents and purposes, a 99.9% result is considered definitive proof. You can read more about whether paternity DNA results are 100% accurate on our blog.
2. What is the difference between a "Peace of Mind" test and a "Legal" test?
This is perhaps the most critical distinction to understand. The testing process in the lab is the same, but the collection process is entirely different.
- Peace of Mind DNA Test: This uses an at home paternity kit. We send the kit to your address, you collect the cheek swabs yourself, and mail them back to us. These results are for your personal information only. They are not court-admissible because there is no independent verification of who provided the samples.
- Legal Paternity Test UK: If you need results for child maintenance disputes, changing a birth certificate, or court proceedings, you must opt for a legal test. This requires a "chain of custody." A trained professional must collect the samples, verify the identity of all parties with photo ID, and oversee the entire process.

3. Can you take a DNA test while pregnant?
Yes, you can. This is known as a non invasive prenatal paternity test (NIPP). In the past, prenatal testing required invasive procedures like amniocentesis, which carried a risk of miscarriage. Modern technology has changed that.
We can now perform a prenatal dna test using a simple blood draw from the mother and a cheek swab from the alleged father. This can be done as early as 7 to 8 weeks into the pregnancy. The mother’s blood contains tiny fragments of the fetus's DNA (cell-free DNA), which our lab can isolate and compare. It is 100% safe for both the mother and the baby. If you are wondering if this is the right path for you, check out our guide on taking a DNA test while pregnant.
4. How does immigration DNA testing work?
If you are applying for a UK visa or settlement based on a family relationship, the Home Office or the Passport Office may request a DNA test. This falls under immigration dna testing uk.
These tests must be conducted by a laboratory accredited by the Ministry of Justice. At Brashan DNA Services, we coordinate with accredited labs and international collection points to ensure that samples are collected under strict legal standards, even if family members are currently in different countries. For more logistical details, see our post on DNA tests for immigration purposes.
5. What if the alleged father is unavailable?
In some cases, the alleged father may be deceased, missing, or unwilling to participate. In these situations, we can look at other biological relationships to establish parentage.
- Sibling DNA Test: This determines if two individuals share one or both parents.
- Grandparent DNA Test: This can confirm a biological link between a child and their paternal grandparents, indirectly proving paternity.
While these tests are slightly more complex than a direct paternity test, they are highly effective at resolving family mysteries. We’ve seen incredible stories, such as sisters meeting for the first time in 50 years, all thanks to sibling testing.

6. Is the mother's sample required?
While we can perform a paternity test with just the child and the alleged father, we strongly advise including the mother’s DNA whenever possible.
Including the mother allows the lab to "mask" the DNA markers the child inherited from her. This makes the remaining markers: those inherited from the father: much clearer to identify. It increases the statistical certainty of the result and reduces the risk of an inconclusive finding, especially in cases where the alleged fathers might be closely related.
7. How long does it take to get results?
In the world of DNA testing, waiting is the hardest part. Most companies take 3 to 5 working days. At Brashan DNA Services, we have built our reputation on speed. We offer same-day results for most of our standard paternity tests once the samples reach our UK-accredited laboratory.
To ensure this speed, we recommend using guaranteed special delivery when returning your samples. If your samples reach our lab by the morning cutoff, you will have your results by the end of that same working day.
8. What are the consent requirements?
In the UK, the Human Tissue Act 2004 regulates how DNA samples are handled. It is illegal to test someone’s DNA without their valid consent.
- Adults (16+): Must sign their own consent form.
- Children (Under 16): A person with parental responsibility must provide consent on the child's behalf.
Failure to provide proper consent means the laboratory cannot legally process the samples. We take these regulations very seriously to protect the privacy and legal standing of everyone involved.

9. How is your privacy protected?
DNA data is the most sensitive information a person has. People often ask, “Can you make your DNA test result private?” and the answer is a resounding yes.
Our at home paternity kit is sent in discreet, plain packaging with no mention of "DNA" or "Paternity" on the outside. Furthermore, we do not sell your data to third parties. Your results are sent only to the person who ordered the test and are stored on secure, encrypted servers. Discretion is one of our primary USPs.
10. How do you choose the right DNA testing service?
Not all DNA tests are created equal. When searching for a provider, you should look for three things:
- Accreditation: Ensure the laboratory is ISO 17025 accredited and, for legal cases, Ministry of Justice approved.
- Speed: If you need answers quickly, verify their turnaround times.
- Support: DNA testing can be emotional. You want a service that provides clear instructions and a human point of contact.
At Brashan DNA Services, we prioritize transparency. Whether you are dealing with a man devastated by a result or a family finally finding a missing piece of their puzzle, we provide the clinical accuracy and professional care required for such a significant life event.
