Are buccal swab samples as accurate as blood samples?
DNA is the same in almost all cells in our body. Once conceived during reproduction, DNA does not change. Therefore, the type of DNA sample used in the test is not going to affect the results. Our laboratory’s standard samples are buccal swab and blood specimens. We also accept non-standard samples such as organ tissue, hair (with roots), cigarette butts, tooth brushes, and other frequently-used personal items.
