Choosing to take a DNA test is a big decision. Whether you are seeking a paternity test UK wide or looking into a sibling dna test to reconnect with family, you want the results to be definitive. While an at home paternity kit is designed to be user-friendly, the "home" element introduces variables that don't exist in a controlled clinic.
At Brashan DNA Services, we provide peace of mind dna test options that are processed in a UK-accredited lab, offering same-day results once the samples reach us. However, the accuracy of those results starts with you. Even the most advanced dna testing services cannot fix a sample that was collected incorrectly.
Here are the seven most common mistakes people make when using a home kit and exactly how to fix them to ensure you "erase doubt" the first time around.
1. Do you read the instructions before opening the swabs?
Most people treat an at home paternity kit like a piece of flat-pack furniture, they only look at the manual when they get stuck. This is a critical error. The moment you break the seal on a sterile swab, the clock starts ticking on potential contamination.
The Fix: Before you even wash your hands, sit down and read the instruction leaflet from start to finish. Ensure you have all the components: the swabs, the specimen envelopes, and the consent forms. Brashan DNA Services prioritizes transparency, so our instructions are written to be clear and functional. Understanding the sequence of events prevents frantic searching for a pen or a seal while holding a live DNA sample in your hand.

2. Are you touching the tip of the swab?
It sounds simple, but this is the leading cause of failed samples. Your fingers are covered in your own DNA, oils, and bacteria. If you touch the white tip of the swab intended for the child or the alleged father, you have effectively cross-contaminated the sample. This can lead to an "inconclusive" result, requiring a retest and delaying your same-day results.
The Fix: Handle the swabs only by the plastic or wooden handles. Collect the sample carefully by keeping your fingers far away from the absorbent tip. If you do accidentally touch the tip, do not try to clean it or blow on it. Call us at +442046204341 to request a replacement swab immediately.
3. Did you eat, drink, or smoke before collection?
A peace of mind dna test relies on buccal (cheek) cells, not saliva. However, anything in your mouth can interfere with the extraction of those cells. Food particles can degrade the DNA, while chemicals from cigarettes or sugar from drinks can mask the genetic markers our lab needs to see.
The Fix: Ensure all participants have an empty mouth for at least 30 to 60 minutes before the test. This means no food, no coffee, no juice, and definitely no smoking. If you are testing an infant, wait at least one hour after their last feeding to ensure no milk residue remains in the mouth. This rule is especially vital for a grandparent dna test or a sibling dna test, where the genetic links are already more complex to identify than a direct father-child relationship.
4. Are you mixing up the specimen envelopes?
In the emotional heat of the moment, it is incredibly easy to put the father’s swab into the child’s envelope or vice versa. If the lab receives a sample labeled "Child" that contains adult male DNA, it triggers a red flag, and your results will be delayed.
The Fix: Label every envelope before you take the swabs out of their packaging. Write the name, date of birth, and relationship (e.g., Alleged Father, Child) on the envelope while it is still flat. Once the sample is collected, place it directly into the corresponding envelope. This simple step ensures the discretion and accuracy of our dna testing services.
5. Are you scrubbing the cheek vigorously enough?
A common misconception is that you just need to get the swab wet with spit. This is incorrect. We are looking for the skin cells on the inside of the cheek. If you only "wipe" the area gently, there may not be enough DNA for the lab to create a profile.
The Fix: Scrub the inside of the cheek firmly for about 30 to 60 seconds. You should use enough pressure that you would feel it, but not so much that it causes pain. Rotate the swab as you rub to ensure the entire surface of the tip is covered in cells. This is the best way to ensure that paternity dna results are 100% accurate upon the first lab run.
6. Are you using the wrong test for your situation?
One of the biggest mistakes involves using an at home paternity kit for a situation that requires a legal paternity test uk. If you need results for a court case, a child maintenance dispute, or to change a name on a birth certificate, a home kit will not work. Home kits lack the "Chain of Custody" (a neutral third party verifying IDs) required by UK courts.
Similarly, if you are navigating the Home Office requirements, you must specifically request immigration dna testing uk services.
The Fix: Determine your end goal before ordering.
- If you just want to know the truth for yourself: Use a peace of mind dna test.
- If you need it for legal or official use: Order a legal paternity test uk.
- If you are pregnant and need answers now: Opt for a non invasive prenatal paternity test.
For those specifically looking at residency or visas, please review our guide on the dna test for immigration purposes.
7. How are you storing the samples before posting?
DNA is a biological material. If you seal a wet swab inside a plastic bag, you create a greenhouse effect that encourages the growth of mold and bacteria. This will destroy the DNA before it ever reaches our UK-accredited lab.
The Fix: Use only the paper envelopes provided in the kit. Paper allows the swab to breathe and dry naturally, which preserves the DNA. Once the envelopes are sealed, send it to the lab as soon as possible. We recommend using a guaranteed special delivery service to ensure the samples reach us quickly and safely.
