How to take a DNA test at home 2018-09-11T11:18:07+00:00


Please do not eat, drink (water is fine), use tobacco or recreational drugs, or chew gum for at least 30 minutes before providing your DNA sample.

How to Collect a DNA Sample

Buccal swabbing is convenient because it doesn’t require a medically trained professional. By following these simple steps,  anyone can collect a buccal swab sample for DNA relationship analysis. Here’s how:

1. Verify that the subject’s mouth is empty.

2. Wash your hands with soap and water, or put on a rubber or latex glove.

3. Open the DNA collection kit.

4. Choose a sterile cotton swab (either a buccal swab if you ordered a Bio-Gene DNA collection kit or cotton swab if you are making your own kit).

5. You should have one package of swabs if you requested a Bio-Gene DNA collection kit. There are two swabs in each package. Carefully remove the buccal swabs from one package.

6. Avoid touching the swab tip with your fingers, gloves or against any surface.

7. If you are using regular cotton swabs (Make Your Own Kit option) please cut off the end you are not going to use for the DNA collection without touching the cotton tip you will be putting in the mouth.

8. Have the subject open his or her mouth and immediately bring the swab tip to inside of cheek.

9. Gently rub and rotate swab along the inside of the cheek for 20-30 seconds, ensuring that the entire swab tip has made contact with the cheek.

10. Immediately remove the swab, being careful not to touch the swab tip against teeth, lips, or other surface.

11. Let the swabs air dry for up to one hour.We recommend using a short glass and placing the oral swab cotton side up inside of the glass to allow it to dry. Make sure that swabs from different test participants do not at any point come into contact.

12. Repeat until you have used one (1) swabs per cheek for a total of two (2) swabs collected per person.

13. Place the dry swabs directly into one collection envelope. Each person MUST have their own envelope. DO NOT combine samples into the same collection envelope.

14. Label the envelope with identifying information.

If you are making your own DNA kit please make certain all the information listed below in on your envelope. Here is an example of a properly completed collection envelope from a Bio-Gene DNA kit (collection envelopes may vary in appearance):

The following information MUST be included:

Your Bio-Gene DNA Case Number – must be on EACH envelope

Name of the person whose DNA sample is in the envelope

Type of test being performed

Suspected Relationship – ONLY list the specific relationship as listed on your order form (for example: paternity, sibling, grandparent, child etc). DO NOT list other possible relationships or information. If multiple possible relationships are listed (for example: possible sibling or cousin; possible sister or aunt; possible father or grandfather, etc.) the samples will be discarded and you will need to recollect.

15. Finally, place all collection envelopes into the provided prepaid mailer or into a larger envelope for shipping (if you chose the Make Your Own Kit option). Please record any tracking information you may have to verify delivery of your samples to the lab. Bio-Gene DNA does not recording tracking numbers on prepaid mailers as we leave that choice to you.

16. Send the samples to the lab for processing.

17. You will be notified by email to log in to your secure client page once ALL samples have arrived at the lab. You will also be provided a “Due Date” for your results which will be the day they should be posted to your client page. All results are posted ONCE per day, no later than 8:00 PM PST on regular business days.


Non-Standard Alternative Samples

IMPORTANT: If you have ordered testing for non-standard samples (anything other than a mouth swab) please make certain that the sample fits into the collection envelope. If you need to trim the sample (such as a hat band or piece of clothing) please do not touch the area to be tested and cut out only the section to be tested. Non-standard samples that are not ready to test will be discarded and a new sample requested. At no time should you ever place a DNA sample into a plastic bag, only a paper envelop to avoid bacteria forming on the sample.
