What is the primary use of a buccal DNA collector?

The primary use of a buccal DNA collector is to gather cheek cells for DNA testing. This method involves swabbing the inside of a person's cheek, which collects epithelial cells that contain DNA. Buccal swabs are a non-invasive and efficient way to obtain a DNA sample, allowing for easier collection especially in a detention environment.

This method is widely accepted in forensic science and law enforcement for identifying individuals, conducting familial searches, and solving cases. It is important because it can provide reliable genetic material for a variety of applications, including criminal investigations and paternity testing. The ease of collecting these samples without the need for specialized medical training further supports its primary use in the field.
