The Toxicology Laboratory analyzes various diagnostic specimens for therapeutic drug monitoring and drugs of abuse. The Toxicology Laboratory is located in the Mackenzie Building at the Queen Elizabeth II Sciences Centre.

The Toxicology Laboratory strives to provide accurate, timely results using stringent quality control requirements so physicians, nursing units and hospital clients can provide a high level of care to patients and clients.

There is ongoing method development and learning as new drugs are brought to market and results are required to determine clinical efficacy. Technology is always evolving in the form of new instrumentation, which is incorporated into the laboratory to provide more sensitive and accurate determinations.

Frequency Of Testing


  • Anti-rejection drugs such as Tacrolimus, Cyclosporin and Sirolimus
