If you're looking for cousin matches, ethnicity, etc that is also very reliable and exact…there are no free tests. Although there is a group called DNA Detectives on Facebook that, when they can and IF you can prove extreme financial hardship, sometimes gifts an AncestryDNA kit (with first preference being given to adoptees).If you're looking for genetic health risks that is something to discuss with your doctor.A couple years ago Michigan University was doing a program for research involving a very basic Ancestry style DNA test but 1) results were not very accurate, 2) did not include cousin matching, 3) could not be uploaded elsewhere, and 4) no new tests were being processed as of December 2017
