Returning your sample to the lab

You kit came with a prepaid mailer.

Before preparing your sample for shipment, you will need to register your sample collection tube at We recommend that you ship your collected sample to the laboratory at your earliest convenience.

The transportation supplies for your fecal sample are included in your kit. Simply place the collection tube containing your sample in the plastic specimen bag, and then place the bag directly into the prepaid mailer.

Drop the mailer off at any US Postal Service Mail Box if shipping from within the United States. The box is already pre-addressed and pre-paid.

Note: To protect the privacy of all customers, the lab will only accept samples delivered via postal service or carrier. Do not attempt to drop off your sample directly at the lab.
