Choosing to take a DNA test is a significant life event. Whether you are looking for answers to personal questions or require documentation for a legal matter, the results carry weight. At Brashan DNA Services, we understand that uncertainty is stressful. Our goal is to provide peace of mind dna test results through a process that is fast, discrete, and scientifically rigorous.

However, the process of ordering a paternity test uk can be confusing. Minor errors in the ordering or collection process can lead to delays, inconclusive results, or even legal invalidity. To ensure you get the clarity you deserve, we have outlined the seven most common mistakes people make and how you can avoid them.

1. Not Understanding the Difference Between "Peace of Mind" and "Legal" Tests

One of the most frequent errors is ordering a peace of mind dna test when a legal paternity test uk is actually required.

A "peace of mind" test is for personal information only. You receive an at home paternity kit, collect the swabs yourself, and send them back. Because the laboratory cannot independently verify who the samples belong to, these results are not admissible in a court of law or for official government use.

If you require results for:

  • Child maintenance disputes (CMS)
  • Changing a birth certificate
  • Inheritance claims
  • Immigration dna testing uk

You must opt for a legal test. This involves a "chain of custody" procedure where an independent third party (a professional sampler) verifies the identity of the participants and oversees the collection.

How to avoid this: Assess your end goal before purchasing. If there is any chance you will need to use the results in a legal capacity, always choose the legal option at our shop.

2. Failing to Disclose That Potential Fathers Are Related

DNA testing works by identifying shared genetic markers. Because biological relatives: such as brothers, or a father and son: share a significant portion of their DNA, the laboratory must know if the potential fathers are related.

If two potential fathers are brothers, a standard test might produce a "false positive" or an inconclusive result if the lab isn't specifically looking for the subtle differences between the two related males.

How to avoid this: Always inform the laboratory during the ordering process if there are multiple potential fathers who are biologically related. We strongly advise that, in these cases, both potential fathers are tested if possible. This allows our technicians to perform an extended analysis to ensure 100% accuracy.

3. Contaminating or Tampering with the DNA Samples

When using an at home paternity kit, the quality of the result depends entirely on the quality of the sample provided. Contamination occurs more easily than most people think. Common culprits include:

  • Eating, drinking, or smoking within 30 minutes of swabbing.
  • Touching the tip of the swab with your fingers.
  • Dropping the swab on a surface before placing it in the envelope.
  • Accidentally mixing up the swabs for the father and the child.

How to avoid this: Read the instructions provided in your Brashan DNA kit thoroughly before you begin. We recommend performing the collection in a clean environment. Ensure you do not touch the cotton end of the swab and place each sample into its designated color-coded envelope immediately after collection.

4. Omitting the Mother’s DNA Sample

While it is possible to perform a paternity test uk using only samples from the father and the child, including the mother’s DNA is highly recommended.

The laboratory identifies which half of the child’s DNA came from the mother. This allows the scientists to isolate the remaining half and compare it directly to the potential father. Including the mother’s sample significantly increases the statistical certainty of the result, especially in complex cases where the potential father might be a close relative of the actual biological father.

How to avoid this: Whenever possible, include the mother in the testing process. At Brashan DNA Services, we often include the mother’s processing at no extra laboratory fee to ensure the highest level of accuracy for our clients.

5. Attempting to Test Too Early Without the Right Technology

For many, waiting until a child is born to find answers is not an option. However, attempting to use a standard paternity kit on a newborn without proper preparation, or trying to find "alternative" ways to test before birth, can lead to failure.

If you need answers during pregnancy, you must use a non invasive prenatal paternity test (NIPP). This is a highly advanced prenatal dna test that analyzes the fetal DNA found in the mother’s bloodstream.

How to avoid this: Do not attempt to use "home remedies" or unverified testing methods during pregnancy. Ensure you book a dedicated non invasive prenatal paternity test through a provider that uses a UK-accredited lab. This test can be performed as early as the 7th or 8th week of pregnancy and is 100% safe for both the mother and the baby.

6. Choosing a Provider Based Only on the Lowest Price

It is tempting to choose the cheapest dna testing services available online. However, low-cost providers often cut corners. They may not use UK-accredited laboratories, or they might test fewer "markers" (genetic locations). A test that only looks at 16 markers is significantly less accurate than the 21 or 24-marker tests used by leading services.

Furthermore, budget providers rarely offer the logistics and speed that sensitive situations require. At Brashan DNA Services, we pride ourselves on providing same-day results once the samples reach our laboratory, ensuring you aren't left waiting in limbo.

How to avoid this: Check for accreditation. Ensure the lab is ISO 17025 certified. Look for a provider that offers discretion and clear communication. You can learn more about our standards on our frequently asked questions page.

7. Not Considering Indirect DNA Testing Options

Sometimes, the potential father is unavailable for testing. In these instances, people often assume a paternity test is impossible. This is a mistake.

Genetic relationships can be established through other family members. We offer a range of services for these exact scenarios:

  • Sibling dna test: To determine if two individuals share one or both parents.
  • Grandparent dna test: To establish a biological link between a child and their paternal grandparents.
  • Uncle/Aunt dna testing: To verify a relationship through the potential father’s siblings.

How to avoid this: If the father is deceased, missing, or unwilling to participate, do not give up. Explore our pages on confirming half or full dna testing for siblings or grandparent dna testing to find a viable alternative.
