Quarter inch diameter of mane (preferred), tail, or body hair with the roots/follicles intact.
Approximately 1/4-inch in diameter of mane (preferred), tail, and/or body hair should be submitted for testing. Hair should be pulled, not cut, ensuring the roots/follicles remain intact. Strands of hair can be pulled from multiple locations of the same source (i.e., mane) in order to achieve the required amount. If collecting multiple samples, use new disposable gloves each time. Wash hands between each collection if gloves are not worn.
Sealed, leak-proof plastic bag or container.
Place sample in foil, rubber band, or paper strip secured with a paper clip. Do not use tape of any kind on the sample. Do not store samples in the refrigerator, freezer, or direct sunlight.
