Laboratory Medicine Services


About Us

St. Joseph’s laboratory services provides support both to patients when being cared for in the Health Centre and people living in our community who require ongoing treatments and monitoring of medical conditions.

Every year, our laboratory performs approximately 2.75 million tests, and provides reference testing for a number of hospitals in the GTA. We are also involved in clinical studies, Medical Laboratory Technologist and Assistant (MLT and MLA) student education, and research activities. We were the first laboratory in Canada to replace cardiac enzymes with routine Troponin testing for the diagnosis of Acute Myocardial Infarction in 1995.

Please select from our inpatient and outpatient laboratory services tabs to learn more about the services we provide for our patients.

Accreditation and Licenses

Our laboratory regularly obtains licenses and is accredited to ensure we meet all requirements to operate in Ontario.

The Institute for Quality Management in Healthcare (IQMH), funded by the Ontario Minister of Health and Long-Term Care (MOHLTC), sets up quality management criteria for Ontario’s licensed medical laboratories and ensures that these criteria are met (i.e. ISO 15189). St. Joseph’s laboratory meets the highest standards of laboratory services and is competent in carrying out clinical testing. IQMH also offers proficiency testing, which is used to verify the accuracy of laboratory testing by comparing it with other laboratories. This means any licensed medical laboratory in Ontario will give accurate and consistent results to your doctor. Under the Laboratory and Specimen Collection Centre Licensing Act, the MOHLTC provides license when all the standards and requirements are met.

Laboratory tests, such as blood tests, are essential in assisting your physician to diagnose, treat and monitor your medical conditions. St. Joseph’s outpatient lab offers a convenient location for patients in our community to get their blood work done. Physicians affiliated with the hospital are able to electronically obtain routine blood test results within hours.

Important notice for lab patients

St. Joseph’s Health Centre’s outpatient laboratory is no longer accepting requisitions from community physicians who are not affiliated with (i.e. do not have privileges at) the Health Centre.

Most laboratory tests requested for outpatients are covered by OHIP (Ontario Health Insurance Plan), and can be performed at any of the nearby community lab service providers. You will not incur additional costs for tests covered by OHIP. In many cases, parking is free at the community labs.

This change is in keeping with the practice at most Ontario hospitals and will allow St. Joseph’s to provide better service to the emergency patients and other areas of the hospital.

Patient and family frequently asked questions

Where is the outpatient lab located?
The outpatient lab is located on the ground floor in the Glendale wing near the Tranquility entrance (Map). We are open Monday to Friday from 8:00 a.m. to 4:00 p.m. The last patient is taken at 3:45 p.m. Please contact 416-530-6275 for more information. If you would like help getting around the hospital, ask a volunteer or go to the Information Desk.

How do I get my blood work done and how does it all work?
Your doctor may request to have a sample of your body fluid (e.g. blood, urine, stool, sputum) sent for testing. The tests ordered by your doctor will determine what samples are required, how and when they are collected, how they are transported to laboratory and how they are tested.

  1. Ask your doctor if you need to do any preparations before getting your blood work done, such as fasting. Ensure you follow your doctor’s instructions before arrival.
  2. Registration is required before getting your blood work done. Registration is done at the Ambulatory Care Centre registration office by the Tranquility entrance. The registration office is open on weekdays from 7:30 a.m. to 3:45 p.m. Please remember to bring the requisition for your blood work signed by your doctor and your Health Card (OHIP). If you were asked by your doctor to collect your urine or stool, and you need to pick up the container and instructions, please go directly to the outpatient lab and speak with one of our medical laboratory technicians.
  3. Once registered, go to Waiting Area A.
  4. Take a number and be seated. Please remain in Waiting Area A. A medical laboratory technician will call for you by number.
  5. Your samples will be collected by our trained medical laboratory technicians. They will deliver your samples to our laboratory at St. Joe’s to be prepared and analyzed. Results are then sent to your doctor.

What do I do if I have been asked to collect my own sample?
Some tests will require you to collect your own body fluids, such as urine or stool. You may even have to do this over a period of time. It is important that you follow the collection instructions provided by the medical laboratory technicians carefully to ensure the test results are accurate.

If you were asked by your doctor to collect your urine or stool and you need to pick up the container and instructions, please go directly to the outpatient lab and speak with one of our medical laboratory technicians. You do not have to pick up a number and wait.

Will I have to fast before my blood work?
It will depend on the type of blood test ordered by your doctor. Your doctor will tell you if there are any specific instructions you need to follow before you have your blood work done. For the majority of blood tests, you can eat and drink as normal. Here are some tests for which you will be asked not to eat or drink fluids other than water before your blood is taken:

  • Fasting glucose
  • Fasting lipid profile

How long does it take for my doctor to get the results?
If your physician is affiliated with St. Joseph’s, most routine tests are reported electronically within 24 hours.  All other special tests where your samples are sent out to other laboratories in and outside the province will take from several days to several weeks.

Can I get a copy of my lab results?
Lab results are sent directly to your doctor. We do not provide lab results to patients. You can access copies of all your records in the Health Records Department. St. Joseph’s does offer MyChart. For more information, visit

Can I wear scented cosmetic products to St. Joseph’s?
No. In order to provide a safe and healthy working environment for our patients and staff, St. Joseph’s Health Centre has implemented a Scent Free Environment policy. We ask you to be considerate when visiting St. Joseph’s.

Please review our hospital policy here.

If you have sensitivity to scented products or you are feeling unwell due to odours from scented cosmetic products while in the Outpatient lab, please let one of our staff know immediately.

As the needs of our patients change, we continue to evolve to meet the needs of our clinical programs. We make use of new analyzers with improved testing methods, automated systems, research, continuous education for our staff and efficient use of available resources to maintain a position as a major diagnostic service laboratory.

Our departments

Our Core Laboratory, which includes Chemistry, Hematology and Transfusion Medicine, is open 24 hours, every day of the week to support the care provided for our inpatients and those visiting the Emergency Department.

Transfusion Medicine

We are responsible for providing blood and blood products for transfusion (e.g. blood transfusion is where component(s) of donated blood is added to your own blood via your veins in your arm). Blood is composed of red cells, white cells and platelets suspended in plasma, which is the fluid portion of your blood. Your doctor may transfuse any one of these components depending on your need. You may require transfusion due to surgery, injury or disease.


In Chemistry, we analyze samples of your body fluids to monitor your health or to diagnose disease. The majority of testing is done on plasma, which is the watery part of your blood. Other tests can be done on urine, fluids around your joints or organs, and on stools. These tests allow physicians to understand the underlying conditions that may be associated with your symptoms. Chemistry is the largest area of testing within the lab and includes tests that can monitor diabetes, kidney function, hormonal changes, cardiac or lung function, lipid disorders, drug reactions, and much more!


In Immunology, we assess the immune system’s function to determine if a disorder such as immunodeficiency or autoimmunity may be present. Immunodeficiency is when our body is missing important proteins or antibodies that protect us from infection. Some people who are treated with chemotherapy develop immunodeficiency, so physicians need to monitor this very carefully. Autoimmunity is when the body inappropriately produces antibodies that target and damage our own cells. One common autoimmune disease we test for is Lupus.

The Immunology lab St. Joseph’s Health Centre is unique, as it is the only lab in Ontario to offer special testing for disorders such as myositis and optic neuritis. Labs from all over Canada send us their patient samples for testing and we are continuing to grow as a Center of Excellence, providing exceptional service and fast turnaround times.

Point of Care Testing

Point of Care Testing (POCT) refers to any diagnostic testing done outside the laboratory in close proximity to where the patient is receiving care (e.g. at the bedside). This allows healthcare providers to obtain a quick and accurate result on a small sample of blood or urine, without having to send it to the lab for analysis. The most common test in POCT is the measurement of blood glucose levels. Although POCT devices are mainly operated by nurses, the laboratory establishes and oversees the testing policies and procedures, provides user training, and ensures that the highest levels of quality are met.


In Hematology we test cells in the blood for disorders such as Leukemia and Anemia, and may also detect the presence of a blood infection. By examining your red blood cells, white blood cells and platelets, we can provide your doctor with a complete blood count (CBC), which is an important measure of health. We also investigate bleeding disorders by analyzing how quickly your blood clots, and monitor patients taking anticoagulants (blood thinners). Another important group of disorders that we test for are the “Hemoglobinopathies”, which are diseases that affect the structure of hemoglobin, a component of red blood cells that helps to carry oxygen to our tissues. These include Sickle Cell Disease and Thalassemia.


In Microbiology, we employ various methods to determine the bacteria, fungi and viruses that invade your body. We also test the effectiveness of antibiotics against the particular bacteria in the sample to allow your doctor to effectively treat the infection. Our Microbiology team also assists with the Health Centre’s Infection and Prevention Control team in management of infectious diseases by providing comprehensive consultation.

Anatomical Pathology/Cytology

We provide histology services which include consultations and histotechnology techniques on surgical, cytological and autopsy materials. This involves processing, embedding, microtomy and/or staining of paraffin-embedded and frozen tissues with a variety of specialized histochemical stains.

A team comprising of Pathologists and Pathologists Assistants also perform hospital-consented autopsies and provide comprehensive service for partial or complete post-mortem examination.

In Cytology, our Pathologists and Cytotechnologists examine cells from various body sites to determine cellular pathology (e.g. Pap test is a cytopathology test that is used to screen and diagnose cervical cancer). In contrast to histopathology, where whole tissues are examined under the microscope, cytopathology is where free cells or tissue fragments are examined. Our dedicated Cytotechnologists assist physicians in obtaining the optimal content of the tissue from the patients, which contributes to accurate diagnosis by the pathologists.

Phlebotomy Team

Phlebotomists are medical laboratory technicians trained to draw blood from patients for testing. Our laboratory has a team of skilled phlebotomists who support the internal (for patients admitted at the hospital) and external clinical programs, such as the outpatient lab and dialysis clinic.
