Swabbing for Evidence
Place the tip of the swab on the surface, rotating slightly to allow any DNA to absorb into the fibers. Allow the sample to air dry by placing the swab tip-first into the proper packaging and label. Once the swab is in the packaging, this can be placed inside an envelope or paper form.
