Any hair that is submitted for testing must have roots or the follicle attached. Hair that has been cut will not produce significant DNA. When submitting hair for DNA testing please ensure the following:
• Wear gloves when handling the samples to avoid contamination
• Do not touch the end of the hair containing the follicle
• 8-10 hairs are required
• Using gloves, place the hair in the plastic bag provided and send to DTL for testing
Finally, place the envelopes or plastic bags into the DTL self-addressed envelope with your submission form and send back to DTL for processing. Please remember to affix a postage stamp.
