When a person touches an object or surface, they leave behind epithelial cells containing their DNA profile. Investigators use sterile cotton swabs to carefully rub or swipe the targeted area to collect any deposited cells. The swabs are then sealed and sent to a crime lab for analysis.

This profile can then be checked against DNA databases to potentially identify the source. Types Ther...
