Who We Are

Calgary Laboratory Services (CLS) is a medical diagnostic laboratory that offers a full range of laboratory services to Calgary and parts of Southern Alberta. Every year more than two thousand physicians access our services to help diagnose, treat and monitor their patients' health.

Through our community collection sites, mobile services, and hospital laboratories, we serve over a million people each year and perform approximately 21 million tests annually.

We invest in the future of healthcare by providing training programs for tomorrow's laboratory professionals, and by taking an active role in medical research through the development of improved methods of disease detection, and new drugs and therapies.

From collecting blood samples to developing new treatments for patient care, we play an important role in the delivery of healthcare.
