Home DNA-Collection Instructions
This quick visual guide is designed to help you collect DNA for at-home testing using cheek swabs
Self Testing: Five Easy Steps
For most types of DNA tests, GameDay DNA requests samples collected with specialized buccal (cheek) swabs. We send you a buccal swab kit containing everything you need to collect DNA safely and easily in the comfort of home, and the process itself is simple. Be sure to completely fill out the information on the paper sample envelope for each test participant before starting the swabbing process. This visual guide is meant to be an additional reference for you but is not a replacement for kit directions, so be sure to read through all buccal swab kit instructions before getting started!
Frequently Asked Home DNA Testing Questions
-
If the sample envelope seems damp, just place it on a clean counter and let it air-dry before placing the envelope into the mailer. This will not compromise the integrity of the DNA in any way.
-
The buccal swab kit we send you contains complete instructions for collecting each test participant’s DNA safely and effectively. We provide three (4) cheek swabs for each person, which you use to firmly swab the inside cheek. This collects more than enough DNA to run the test.
-
Handle swabs with care! If different participants’ swabs touch before being placed in their respective paper envelopes, they might cross-contaminate. Please contact us and we’ll be happy to ship you out new DNA-collection supplies at no additional cost.
-
Please do not put swabs with samples back into the original plastic packaging or into household baggies for storage and/or shipping purposes. Paper sample envelopes included in the kit are ideal receptacles for an organic matter like DNA because the paper “breathes.” When DNA is confined in plastic it can become a breeding ground for mold and the sample quickly becomes degraded. If the lab receives degraded samples, they won’t be able to be tested and the lab will request new samples; this will delay results.
If swabs seem too “wet” after DNA collection, wave them in the air for about 60 seconds before placing them in the paper sample envelopes.
-
Yes; DNA on swabs remains viable for up to 6 months as long as the swabs are stored in paper envelopes and kept in a cool, dry place.
-
As long as cheek swabs are stored in the paper envelopes provided in the buccal swab kit (not in plastic) and are kept in a cool, dry place, samples remain viable for up to 6 months.
-
Cheek swabs are optimal for collecting the amount of DNA necessary for testing, which is why they are GameDay DNA’s choice. The price of testing for postnatal tests includes analysis from DNA obtained through cheek swabs only; it does not include testing other types of samples.
If you want to use other types of samples, be advised there is a non-refundable $150 – 300 fee for a viability test wherein we determine if enough DNA can be extracted from the sample for testing. Contact us for more information at 302.527.1789.
-
The third set of swabs is intended for use by the mother and her participation is included in the price of testing. Because the mother’s participation can sometimes strengthen results, submitting her DNA is recommended but it is not mandatory. If you want to use the third set of swabs to test an additional child, you’ll need to pay an additional lab fee. Contact us at 302.527.1789.
