DNA sample
Crime lab swab
A DNA sample is biological material—blood, saliva, hair, skin cells—collected for genetic analysis.
Law enforcement takes DNA samples from suspects and crime scenes to establish identity or connections: The detective swabbed the inside of his cheek for a DNA sample.
Medical contexts use DNA samples for genetic testing, paternity determination, or ancestry research.
