What is a buccal sample?

A buccal sample is a specimen collected from the inner cheek of the mouth, typically using a swab or a small brush. This type of sample is often used for DNA testing, genetic analysis, or forensic purposes because it is non-invasive and easy to obtain. Buccal samples contain epithelial cells and can provide valuable information about an individual's genetic makeup or health. They are commonly used in medical research, paternity testing, and ancestry exploration.
