Laboratory Medicine

Laboratory Medicine services provide support to Unity Health patients and people living in the communities we serve. Every year, our laboratories perform millions of tests and provide reference testing for a number of hospitals in the GTA.

We are continually evolving to meet all inpatient and outpatient needs by making use of new analyzers with improved testing methods, automated systems, research, education for our staff and efficient use of available resources. Our laboratory staff members include pathologists, microbiologists, biochemists, pathologists’ assistants, medical laboratory technologists, medical laboratory technicians, phlebotomists, transcriptionists and administrative staff.

Appointment information

You don’t need to make an appointment for lab tests. However, please note that we will only perform tests for patients whose physicians have privileges at Unity Health.

Laboratory Medicine at St. Joseph's Health Centre

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

Our departments include:

  • Anatomical Pathology/Cytology. We provide histology services which include consultations and histotechnology techniques on surgical, cytological and autopsy materials.
  • Chemistry. In Chemistry, we analyze samples of your body fluids (eg. blood, urine, stool) to monitor your health or to diagnose disease. The chemistry division specializes in many complex lab tests that are sent to us from across the country. We provide expert guidance to patients with unique endocrinology, lipid, multiple sclerosis and toxicology related disorders.
  • Hematology. 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, which is an important measure of health.
  • Immunology. In Immunology, we assess the immune system’s function to diagnose disorders such as immunodeficiency or autoimmunity. 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.
  • Microbiology. In Microbiology, we employ various methods to determine the bacteria, fungi and viruses that invade your body and detect diseases like hepatitis, blood stream infections, tissue infections, influenza and pneumonia. We also test the effectiveness of antibiotics against the particular bacteria in the sample to allow your doctor to effectively treat the infection.
  • Phlebotomy. Phlebotomists are medical laboratory technicians trained to draw blood from patients for testing. We have a team of skilled phlebotomists who support the internal and external clinical programs at Unity Health.
  • Point of Care Testing. Point of Care Testing refers to any diagnostic testing done outside the laboratory in close proximity to where the patient is receiving care such as at the bedside. This allows health-care 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.
  • Specimen Receiving. Our trained laboratory technicians receive specimens from internal and family health team outpatient blood labs. Technicians verify, enter information of specimens into the system and submit them to the labs for testing.
  • Transfusion Medicine. In Transfusion Medicine we perform the testing needed to provide blood components (red cells, platelets and plasma) and blood products (factor concentrate, RhIG, IVIG) for transfusion.  You may require transfusion due to surgery, injury or disease.  We also perform special testing to help your physician diagnose and/or monitor certain diseases.

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

We also test the effectiveness of antibiotics against the particular bacteria in the sample to allow your doctor to effectively treat the infection.
  • Molecular Biology. The Molecular Biology Laboratory applies DNA and RNA detection techniques to the diagnosis, prognosis and targeted therapy of various diseases, including colon cancer, brain cancer, breast cancer and cervical cancer. Other molecular tests include detection of polyoma viruses, HSV, flu/COVID, molecular investigations of coagulopathies.
  • Phlebotomy. Phlebotomists are medical laboratory technicians trained to draw blood from patients for testing. We have a team of skilled phlebotomists who support the internal and external clinical programs at Unity Health.
