Is a blood sample better than a buccal sample?
No. A buccal sample yields results that are as accurate as those obtained from a blood sample. In fact, since the DNA is identical in each and every cell in a person’s body, a wide variety of biological samples, even dating back several years, can be used because the DNA molecule is highly stable.
