St. Mary’s General Hospital laboratory services ensure the accuracy and timely turnaround of all lab tests from the St. Mary’s lab and from our reference labs including Grand River Hospital. Our laboratory performs approximately 1.7 million lab tests a year and operates 24/7.

Please note that we only provide testing for registered inpatients and existing registered outpatients of hospital programs. Non-registered outpatients testing takes place in the community. Please contact your doctor’s office for the locations of these blood and specimen collection centres.

For registered hospital patients, lab specimen procurement or phlebotomy (blood sample collection) comes to you in whatever part of the hospital you are receiving care.

The laboratory itself, and the highly skilled Medical Laboratory Technologists, phlebotomy and administration staff, are located on the 9th floor.
