Nail clippings may provide a good source of DNA. Freshly trimmed nails (from fingers or toes) work best. The use of nail clippings is particularly useful in cases where DNA testing needs to be carried out on a recently deceased person. It is recommended that one avoids as much as possible touching the nail clippings directly. When submitting nail clippings for DNA testing please ensure the following

Wear gloves when handling the sample to avoid contamination
Place the nail clippings in the envelope provided and send to DTL for testing
Finally, place the plastic bags into the DTL self-addressed envelope with your submission form and send back to DTL for processing.
