How to collect your DNA sample

SelfDecode provides two types of DNA tests based on your global location:

  1. Buccal (Cheek) Swab DNA Test Kit: Only customers located in the USA or Mexico will receive a buccal swab DNA test kit. The kit contains small, sterile swabs that resemble soft cotton tips. These swabs are used to collect cells from the inner lining of your cheek (buccal cells).

*Note: Buccal swab kits will be provided for all orders placed after Sep 1, 2023; for all orders placed before this date, a saliva sample DNA kit will be provided.

  1. Saliva Sample DNA Test Kit: Customers residing in all other countries will receive a saliva collection DNA test kit. The kit contains a sterile, screw-top collection tube with a stabilizing solution. It also includes a funnel that attaches to the collection tube to easily transfer the saliva into the tube without spillage.

Please do not eat, drink, smoke, brush your teeth, or chew gum for at least 1 hour before collecting your sample. If you forget, please email us to purchase a replacement kit.
