How do I ship my sample back to the lab?

Shipping your sample is easy — everything you need is included in your kit. After sealing your specimen in the bio-safe pouch and completing the chain-of-custody form, place both in the pre-addressed return mailer included in your kit. The mailer is pre-paid and pre-addressed to Yenos Analytical in El Dorado Hills, California. Simply drop the sealed mailer at any USPS post office or FedEx location. If using USPS, ask the postal clerk to confirm it is accepted as a biological specimen package (Class 6.2, Category B). Do not deposit in a regular mailbox — take it to a staffed USPS or FedEx counter to ensure proper handling and tracking confirmation.
