As with any evidence, the sooner potential DNA evidence is submitted to the laboratory, the better. Because DNA evidence is susceptible to degradation and contamination, always try to air-dry evidence before it is packaged and keep the sample as cold as possible. If evidence cannot be completely air-dried at the scene, transport it in a leak-proof container to the department's drying room, properly package the evidence in paper, and store it as cold as possible.
