DNA sampling
Taking hereditary material
DNA sampling is the collection of biological material—blood, saliva, hair, skin cells—to extract genetic information for identification or analysis.
Law enforcement uses DNA sampling to link suspects to crime scenes or exonerate the wrongly convicted.
It also appears in paternity testing, medical diagnostics, and ancestry research: The police requested DNA sampling from everyone in the neighborhood.
