For those who have personally tried them, I am looking for a list of the DNA companies and how they physically test. For example, when I did 23andMe I had to spit in a tube.
My grandmother is old and could be tested but I don't think she can muster up enough saliva for the tube - or she would lose interest beforehand.
What companies test with other methods like a cheek swab for example? I think we could manage that.
Suggestions welcome!!!
