Even those with oral sensory issues can do this with no discomfort. My boys, who have issues with toothbrushes and food textures, were able to do it. They are all the proof you truly need.
Here are the kits:
4 Longstemmed cotton swabs
4 Computerized tags
Foam collection holder
Your child swallows to reduce any saliva in their mouths. Then they take the end of the swab, swipe it on the inside of one of their cheeks for about ten seconds. They take the swab out of their mouths and wave it in the air to dry. You then put the computerized tag on the end of the swab and place it in the slit provided in the foam holder. Never touch the cotton tip with your hands. It will contaminate the sample.
Finally, take the folder with the cotton swabs, place it inside a stiff envelope, which you then place inside the already pre-addressed envelope.
The reality is that if you or your child are ever called to donate you will not know the person whose life you save. It is something completely and totally selfless. It's a terrific lesson in understanding what it means to be part of the wider community of human beings.

Be the Match
It doesn't matter which organization you donate through, they share their databases.
