Why use a blood sample rather than a cheek swab (buccal smear) sample? Cheek sounds like it would be easier. What is recommended?
Although cheek swabs seem quick and simple, only blood samples are scientifically proven to be the “gold standard” in DNA analysis because 95%* of the time, they can reliably provide large amounts of high quality DNA to analyze. Alternatively, according to some published studies, cheek swab derived DNA samples only have a 25-40%* success rate. *Hansen TV, et al.
