Our pathologists have access to many integrated techniques including histology, immunohistochemistry, flow cytometry, electron microscopy, cancer cytogenetics and molecular diagnostics. These resources enable our team to provide opinions that meet the level of sophistication required by our clients.

Services range from consultations that provide diagnostic advice on complex cases, to routine interpretation of tests, collaborative diagnosis, and technical services.

Our areas of expertise include breast pathology, cardiovascular pathology, cytopathology, dermatopathology, endocrine pathology, gastrointestinal and hepatic pathology, genitourinary pathology, gynecologic pathology, head and neck pathology, hematopathology, neuropathology, pulmonary pathology and renal pathology.

Pathology Disciplines


Autopsy Services

Cytopathology

The Cytopathology Department diagnoses diseases on a cellular level. We typically support the diagnosis of cancer.

Tests:

  • Fine Needle Aspiration and Non-Gynecologic Cytology with Morphologic, Proteomic and Genomic Tumour Analyses
  • Liquid-based Gynecologic (Pap Test) Cytology and HPV Testing

Electron Microscopy

The Electron Microscopy Department uses ultrastructural analysis of cells and microorganisms by Transmission Electron Microscope. High-resolution digitized images are captured and ultrastructural measurements are made for the diagnosis of diseases with ultrastructural footprint.

Histopathology

The Histopathology Department performs a wide range of histological techniques including processing, embedding and staining of tissue sections for initial diagnosis. Special stains demonstrate microorganisms, certain cell types and special structures in tissue. Enzyme histochemistry is used for diagnosis of neuromuscular diseases.

Immunopathology

The Immunopathology Department performs immunohistochemical assays, both diagnostic and predictive, which help UHN Pathologists and oncologists plan the best personalized patient treatment options. Our laboratory uses state-of-the-art platforms, enabling implementation of rare assays. Specialized Immunofluorescence studies focusing on kidney and skin biopsies are performed and used by UHN renal pathologists and dermatopathologists.

Surgical Pathology

Surgical Pathology receives and evaluates all tissue specimens collected from across the hospital and consult material from other hospitals.

Our team of pathologists' assistants, with support from pathologists, handle, dissect and sample the specimens received in the Surgical Pathology lab as well as LMP's Autopsy Services. After microscopic review, a diagnosis is made by a pathologist and shared with a physician.

Research

  • Fee for service; Animal and Human research studies
  • Routine histological services, whole-mount tissue processing
