How a Sample is Taken


A sample kit for your DNA test contains a toothbrush-like swab, which has a sponge instead of bristles. This is rubbed vigorously on the inside of your cheek, then the sample obtained is put into a special bottle provided. Actually two samples are taken, so that there is a backup sample should the first one not return enough DNA material. Then the two samples, in their special holders, are placed in the packaging provided by FamilyTreeDNA (FTDNA) and returned directly to them. This is designed to be quick and easy.

The sample is analyzed by a genetics laboratory at the University of Arizona, Tucson. This is your test. The results (your signature) will be returned to you at the completion of the testing process, which normally takes a month or so.
