How to Do a DNA Test

The DNA sampling pack we will send to you contains comprehensive instructions for collecting and dispatching a DNA sample using buccal cheek swabs.

It is important that you follow the instructions carefully and return the DNA samples with payment, using the reply envelope you will find in the DNA testing kit. If you wish to have your DNA samples taken professionally we can arrange for this to be done either at your home, or a local Doctors surgery at extra cost.

The home collection of DNA samples involves utilising a special swab (like an oversized cotton bud) that is rotated on the inside of the cheek to collect the cells resident there. This swab is then placed, (carefully to avoid contamination) within the provided DNA sample collection envelope which is securely sealed and returned to us for analysis at our laboratories. At this time we will ask you to provide sufficient information so that we can ensure your file is unique and we can honour our responsibilities under the Data Protection Act.

Peace of Mind DNA Test (Back to top)

  1. Do not drink coffee or tea, or use tobacco products for 4 hours prior to sampling. Samples containing coffee, tea or tobacco residues may not process properly!
  2. Wash your hands thoroughly and rinse applicant’s mouth three times with warm water. Do not use toothpaste or mouthwash. (For infants – allow them to drink water at room temperature from a bottle or wait 2 hours from last feeding).
  3. Take the first pair of swabs, which are to be used to collect the first applicant’s DNA sample. Remove the first swab from its sterile packaging, taking care not to touch the tip of the swab. Collect cheek cells by rolling the tip of the sample collection swab firmly on the inside of the right cheek (30 times each or for about 1 minute). Be certain to move the swab over the entire inner cheek surface. This action should be firm but not aggressive and should not be uncomfortable.
  4. Repeat this process for the same individual with the second swab on the inside of the left cheek. You must submit two swabs per person.
  5. Allow the swabs to air dry at room temperature for at least 15 minutes. To avoid contamination, do not allow the tips of the swabs to touch anything.
  6. Place the used swabs in the first sample collection envelope (do not put back in plastic packaging) and ensure that you clearly complete and sign the details required on the outside of the envelope. Be sure to seal the envelope firmly.
  7. Take the second pair of swabs, which are to be used to collect the second applicant’s DNA sample and repeat the sample collection process (steps 2–5).
  8. Place the 2nd pair of used swabs in the second sample collection envelope (do not put back in plastic packaging) and ensure that you clearly complete and sign the details required on the outside of the envelope. Be sure to seal the envelope firmly.
  9. Repeat the sample collection process if you are requesting analysis of additional applicants.
  10. Once all DNA samples have been collected, applicants (or their legal guardian) should sign each relevant section as well as their sample collection envelope.
  11. The completed registration forms and sample collection envelopes should be sealed in the reply envelope provided and returned to us (we recommend Recorded or Special Delivery).

Court Approved DNA Test (Back to top)

Arranging your sampling appointment(s)

  1. Choose a sampler. To comply with current legislation, samples must be taken by a health professional. You may either ask your GP or another local doctor. Alternatively, we may be able to suggest a doctor in your area, please contact us for details. Please note that the doctor may charge a fee for taking the DNA sample and this should be negotiated when making an appointment. The doctor’s fee is not included in International Bioscience’s charge.
  2. Once you have arranged an appointment with your chosen doctor, complete and return the registration forms to us, together with your payment, and we will send the DNA testing kit direct to the sampler. You should allow at least seven days for your paperwork to reach us and for the DNA testing kit to reach your chosen doctor.
  3. You will need to take two full-faced, passport-sized photographs of each person to be tested (including children) and current photographic identification (passport or photo driving licence and utility bill) with you to the appointment for identification purposes as well as the doctor's fee.

*IMPORTANT NOTICE: The sampler may charge you if you fail to keep an appointment without giving notice.

Collecting your DNA sample

  1. The doctor will verify identification and sign the back of the photographs to confirm they are a true likeness of the person to be sampled as follows: “I, doctor’s name, confirm that this photograph is a true likeness of donor’s name”, date, doctor’s signature.
  2. Do not drink coffee or tea, or use tobacco products for 4 hours prior to sampling. Samples containing coffee, tea or tobacco residues may not process properly!
  3. Wash your hands thoroughly and rinse applicant’s mouth three times with warm water. Do not use toothpaste or mouthwash. (For infants - allow them to drink water at room temperature from a bottle or wait 2 hours from last feeding).
  4. Take the first pair of swabs, which are to be used to collect the first applicant’s DNA sample. Remove the first swab from its sterile packaging, taking care not to touch the tip of the swab.

  7. Place the used swabs in the first sample collection envelope (do not put back in plastic packaging) and ensure that you clearly complete and sign the details required on the outside of the envelope. Be sure to seal the envelope firmly. The two passport-sized photographs of the first applicant, endorsed on the back by the doctor, should be stapled to the sealed sample collection envelope.
  8. Take the second pair of swabs, which are to be used to collect the second applicant’s DNA sample and repeat the sample collection process (steps 3–6).
  9. Place the 2nd pair of used swabs in the second sample collection envelope (do not put back in plastic packaging) and ensure that you clearly complete and sign the details required on the outside of the envelope. Be sure to seal the envelope firmly. The two passport-sized photographs of the second applicant, endorsed on the back by the doctor, should be stapled to the sealed sample collection envelope.
  10. Repeat the sample collection process if you are requesting analysis of additional applicants.
  11. Once all DNA samples have been collected, the doctor should sign each relevant section of the registration forms and complete the Doctor's Appointment section on page 3. The applicants (or their legal guardian) should sign each relevant section as well as their sample collection envelope.
  12. The completed registration forms and sample collection envelopes (with endorsed photographs attached) should be sealed in the reply envelope provided and returned to us by the doctor (we recommend Recorded or Special Delivery).

DNA Test For Immigration (Back to top)

Follow the steps as per the Court Approved DNA Test above.

For immigration cases where one or more applicants currently reside outside the UK, samples must be taken at the British High Commission or an approved clinic in that country. When completing the registration form, please provide a contact name, address and reference number (if applicable) for the relevant embassy. If you are able to provide passport numbers for each participant and a UK Border Agency case reference number it will allow us to process your case more quickly.
