Self-Collection of DNA Test Sample at Home – Easy Step by Step Process


Collecting a DNA sample at home using a cheek swab is a relatively simple process. Here are the steps you can follow:

Materials Needed:

  1. DNA sample collection kit (usually provided by a DNA testing service).
  2. Clean hands and a clean, well-lit workspace.
  3. A mirror (optional, but it can help with swabbing the inside of your cheek).


  1. Prepare the Kit:
    • Ensure that you have the DNA sample collection kit provided by the testing service.
    • Read the instructions and any accompanying paperwork carefully before you begin.
  2. Wash Your Hands:
    • Start by thoroughly washing your hands with soap and water to remove any contaminants.
  3. Gather the Swabs:
    • Open the kit and locate the cheek swabs provided. They typically look like long cotton-tipped swabs.
  4. Prepare the Swabs:
    • If the kit includes multiple swabs, ensure you know which one is for you (the person providing the sample).
    • Avoid touching the cotton tip of the swab to prevent contamination.
  5. Swab Inside Your Cheek:
    • Using a mirror (if available) can help you locate the inside of your cheek more easily.
    • Take one of the swabs and firmly rub it against the inside of your cheek. You should do this for about 30 seconds on one side.
    • Be gentle but ensure that the swab collects enough cells. It’s common to feel a slight tingling sensation, but it should not be painful.
    • Repeat the same process on the other cheek with a new swab if required.
  6. Allow Swabs to Dry:
    • After swabbing both cheeks, allow the swabs to air dry for a few minutes. Do not touch the cotton tips to any surface during this time.
  7. Secure the Swabs:
    • Once the swabs are dry, carefully place them back into the collection tube or container provided in the kit. Seal the container securely.
  8. Complete the Paperwork:
    • Fill out any required paperwork or forms that are included with the kit. This may include your personal information, consent, and other relevant details.
  9. Mail the Kit:
    • Place the sealed sample container and any completed paperwork in the provided return envelope or package.
    • Follow the instructions provided in the kit for mailing the sample back to the testing service. This may involve using prepaid postage or a specific mailing address.
  10. Wait for Results:
    • After mailing the sample, you will need to wait for the testing service to process it and provide you with the results. The turnaround time can vary depending on the service and the type of test being conducted.

It’s important to follow the instructions provided by the specific DNA testing service you are using, as they may have slightly different procedures or requirements. Additionally, be sure to maintain the integrity of the sample by avoiding contamination during the collection process.
