Sometimes a lab result is sent to you incorrectly.  In the Message Centre > My Mail, marking it as 'Seen' will only hide it from the display but it will still be included if you use the 'Print All' option.

To completely remove the result:

  1. Go to the configuration icon (left-hand window - far left icon) and UNCHECK the option the 'Hide message if: Seen'
    

  2. Find and select the result to be deleted

  3. In the right-hand window, check you have the correct result selected then click on the Delete button (you may need to stretch the window further to see the icon).
     

  4. Go back into the configuration and check ON the 'Hide message if: Seen'
