I have a prescription for a blood test

The Montreal Heart Institute's Test Centre has a walk-in blood collection service and is also home to the largest Anticoagulation Clinic in Quebec. A team of medical technologists, all of whom are members of the Ordre professionnel des technologistes médicaux du Québec, collect blood samples from inpatients and outpatients.

A pre-test fasting period of 6 to 12 hours is required depending on the test. Fasting means that you cannot eat any solid foods or drink any liquids other than water. Note that water is allowed in reasonable quantities. Avoid smoking.


On the morning of the test, do not take any over-the-counter medications or supplements (vitamins). After your test, and upon your doctor's advice, take any prescription medication that you were scheduled to take in the morning.
