What is Ontario Laboratories Information System (OLIS) Deployment?

The Ontario Laboratories Information System (OLIS) is a system that connects hospitals, community laboratories, public health laboratories and practitioners to facilitate the secure electronic exchange of laboratory test orders and results. Clinicians using an OntarioMD-certified electronic medical record (EMR) can access the latest lab results for their patients or perform patient queries.
