Blood Testing

All participants will provide blood work at three times throughout the study, once at the beginning, once at the 6-month mark (6 months from your first vaccine if you have been vaccinated, or 6 months from the first blood sample if not), and again at the end of the study. If you are already due to give your 6-month sample but have not yet provided your first sample, please just skip the first sample. You can retrieve a requisition to obtain your blood work in the user portal. We may send you a reminder if needed!

Blood samples are preferred however, if the above labs do not service the area where you live, please contact your provincial study coordinator to obtain a dried blood spot kit. The dried blood spot kit will allow you to collect a sample of your blood at home that can be mailed to the lab for analysis.

Please review the safety protocols on the lab website prior to scheduling or attending an appointment.
