This research study aims to improve the medial assessment (e.g. diagnosis, treatment) of pregnant individuals across Canada.

Our findings will be used by healthcare providers in order to compare healthy and normal blood levels to those of their sick patients in pregnancy.

Participation requires the completion of informed consent (online), a health questionnaire (online), and a small blood donation.
