Once you’ve collected your sample, put the swab back into the original tube and securely seal it. Place the tube into the biohazard bag included in your kit, ensuring that the tube is inserted into the rigid plastic holder inside the bag. Then seal the biohazard bag.
Place the sealed biohazard bag into the cardboard box and close the box securely. Then place the box into the return mailer bag and seal it. Finally, drop off your sample at a FedEx dropoff location.
