Specimen Collection

Located in the basement of the Community Tower, the Specimen Collection department provides services for OSMH patients (inpatients, emergency, oncology, pre-operative, registered clinics). Specimen Collection is open Monday to Friday from 9 a.m. to 4 p.m. but closed for lunch between 12 and 1 p.m. (excluding holidays).


Common tests are glucose, electrolytes, cardiac markers, liver function, thyroid function, pregnancy hormones and blood gases. Drug screening for prescription monitoring and illicit use is also performed. Urinalysis is a special test that can detect diabetes, kidney or bladder diseases, and some blood disorders.


Haematology is the study of blood cells (white, red and platelets). Blood is analyzed to provide accurate information for physicians who are diagnosing and monitoring patients. Other haematology tests are for mononucleosis and influenza.

Blood Transfusion

Our team provides sensitive testing methods to ensure the safest blood matches for patient transfusions. Pre-operative testing ensures compatible blood is on hand. The department works closely with Canadian Blood Services to maintain an adequate inventory for our community.


The laboratory identifies bacteria (collected from swabs, tissues and fluids) that invade the body and cause infection. Once the bacteria are identified it is tested for sensitivity to a variety of antibiotics in order to help the doctor select the best treatment. Screening for “super bugs” such as MRSA and VRE takes place and there is strong communication with the Infection Prevention & Control department.

Anatomic Pathology

Surgically removed body tissues are examined by a specially trained physician to find out if disease is present.

Autopsy Pathology

An autopsy is the post-mortem examination and dissection of human cadavers to determine the cause of death and disease processes. Out pathologists work in conjunction with the local coroners to provide autopsy services when indicated.


Cytology plays an important role in diagnosing cancer at a cellular level. Specimens from body secretions and washings are prepared and analyzed to detect cancer before surgery or radiation/chemotherapy begins, often before any symptoms appear.
