Once your samples are sealed in their collection tubes and then sealed in the clear biological samples bag (included in your kit), you can place the biological samples bag in your kit box. You do not need to include your kit instructions or any other documentation included in your kit.
You may, though, wish to take a photo of your biological samples bag or make a note of your unique Kit ID (beginning with YOX-) in case you should need to contact our support team.
Please make sure you have activated your kit (via start.yoxly.com) before collecting or returning your samples!
