Deciding to take a paternity test is a significant step. Whether you are seeking clarity for your own "peace of mind," navigating a complex legal battle, or settling an immigration matter, the process can feel overwhelming. At Brashan DNA Services, we believe that getting answers should be straightforward, fast, and, above all, accurate.
I’m Erada Oguntoye, CEO of Brashan DNA Services, and I’ve seen firsthand how much a simple test can change a person's life. Uncertainty is heavy, but the right information can lift that weight. To help you navigate this process, I’ve put together the 10 most critical things you need to know before booking a paternity test uk.
1. What is the difference between a "Peace of Mind" and a "Legal" DNA test?
The most common question we receive is why there are two different types of tests for the same biological question.
A peace of mind dna test is designed for personal knowledge only. You can use an at home paternity kit to collect samples yourself and mail them back to us. While the laboratory process is identical to a legal test, the results are not court-admissible because there is no independent verification of who provided the samples.
A legal paternity test uk requires a strict "chain of custody." This means an independent third party (like a doctor or a professional sampler) must verify the identity of the individuals being tested and oversee the collection of the DNA. These results are accepted by the Family Law Courts, the Home Office, and the Child Maintenance Service (CMS).
2. How accurate are the results?
When you choose professional dna testing services, accuracy is non-negotiable. Our UK-accredited lab uses STR (Short Tandem Repeat) testing, which is the gold standard in the industry.
A paternity test will provide one of two results:
- Inclusion: The tested man is the biological father. This result typically shows a probability of paternity of 99.9% or higher.
- Exclusion: The tested man is not the biological father. This result is 100% certain.
For official government purposes, such as passport applications, officials often require results showing 99.99%+ certainty. We ensure our testing meets and exceeds these rigorous standards to provide you with definitive answers.

3. Is consent mandatory for DNA testing in the UK?
Yes. Under the Human Tissue Act 2004, it is a criminal offense in the UK to possess or test a person’s DNA without their valid consent.
For an adult, this means they must provide written authority. For a child, consent must be provided by an individual with Parental Responsibility (PR). In the UK, a mother automatically has PR. A father has PR if he was married to the mother at the time of birth or if he is named on the birth certificate (for births registered after specific dates in the UK).
We strongly advise against "secret" testing. Not only is it legally risky, but results obtained without proper consent cannot be used for any official purpose.
4. Can you perform a paternity test while pregnant?
Yes, you no longer have to wait until a child is born to find out the truth. A non invasive prenatal paternity test (NIPP) can be performed as early as the 7th or 8th week of pregnancy.
Unlike older, invasive methods like amniocentesis, a prenatal dna test requires only a simple blood draw from the mother and a mouth swab from the alleged father. Because the mother’s blood contains fragments of the fetus's DNA (cell-free DNA), our lab can compare the two samples with zero risk to the pregnancy.
5. What if the alleged father is unavailable for testing?
In cases where the alleged father is deceased or unwilling to participate, we can often determine paternity through other relatives. These are known as relationship tests.
- Sibling DNA test: Determines if two individuals share one or both parents.
- Grandparent DNA test: Confirms a biological link between a child and the parents of the alleged father.
- Uncle/Aunt testing: Useful when a paternal brother or sister is available. You can find more details on our uncle/aunt DNA testing page.
These tests provide a statistical likelihood of a relationship and are an excellent alternative when direct paternity testing isn't possible.

6. How does immigration dna testing uk work?
DNA testing is frequently used to support visa or citizenship applications where birth certificates are missing or deemed insufficient by the Home Office.
Immigration dna testing uk must follow specific legal protocols. The samples must be collected under a strict chain of custody, and the laboratory must be accredited. We work closely with clients to ensure their results meet the necessary requirements for the Home Office or the Ministry of Justice. If you are in this situation, we recommend visiting our contact page to discuss your specific case requirements.
7. What comes inside an "At-Home" paternity kit?
If you order a kit for personal use from our shop, it will arrive in discreet, plain packaging. Inside, you will find:
- Sterile mouth swabs for the mother, child, and alleged father.
- Sample collection envelopes.
- A clear instruction leaflet.
- Consent and registration forms.
- A pre-paid return envelope to send your samples back to our lab.
The process is painless and takes less than five minutes. You simply rub the swabs on the inside of the cheek to collect skin cells, no needles required.
8. How long does it take to get results?
We understand that the wait for DNA results is the most stressful part of the process. That is why Brashan DNA Services prioritizes speed without compromising quality.
While many providers take 3 to 5 working days, we offer same-day results once the samples reach our laboratory. If your samples arrive at our lab by the morning cutoff, you will receive your report via email by the end of the same business day. This is one of our key service differentiators in the UK market.

9. How is my privacy protected?
Discretion is a pillar of our business. We treat your data with the highest level of confidentiality. Your results are only shared with the individuals who provided consent or their designated legal representatives.
We also ensure that our packaging is unbranded so that no one, not even your postman, knows you are conducting a DNA test. For more details on how we handle your information, you can review our privacy policy.
