  2. Transfer stool. Using the spoon attached to the cap of the yellow vial, spoon stool from different areas of the sample into the vial. Fill vial to the red fill line (just over half full). Carefully mix stool and fluid with the spoon. Replace cap tightly and shake vial vigorously for 30 seconds.

  2. Place in mailer. Fill in your name and address on the shipping label attached to the outside of the provided FedEx mailer. Place kit box (with vials and requisition form) in the bag then seal the self-sticking pouch. 
  3. Schedule pickup. Call FedEx to schedule a pick-up. Dial 1-800-238-5355. When the automated greeting begins say “Rep”. When asked if you are shipping a package say “Yes”. A live person will then answer to help schedule your pickup. Let them know you are shipping using a Billable Stamp.
