There are 3 main types of DNA tests available – autosomal (atDNA), mitochondrial (mtDNA), and Y-chromosomal (Y-DNA) – each one useful for different purposes. It may also be helpful to discuss any concerns with a health professional before ordering a direct-to-consumer genetic test. Genetics in Medicine, 20, 1515-1521.
