AncestryDNA is a simple saliva test you can do in the comfort of your own home. Once you order, you will receive the AncestryDNA kit in the mail in a matter of days. Your AncestryDNA kit includes full instructions, a saliva collection tube, and a pre-paid return mailer (so you don't have additional costs to return your DNA.) After returning your sample by just dropping it in the mail, your DNA is processed at the lab. You then receive an email notifying you that your results are ready to explore on the AncestryDNA website.
