If you cannot print the requisition form or you do not have access to a printer, you will need to take note of the Participant LID number and verification code displayed on the top left portion of your requisition form. LifeLabs® Medical Laboratory Services will be able to print a blank requisition form at the patient centre when you arrive for your appointment and fill in your information.
