Online access to COVID-19 lab test results for Health Care Providers

If you are an authorized Ontario health care provider with access to one of the provincial viewers (ClinicalConnect™, ConnectingOntario ClinicalViewer and eHealth Portal) or an electronic medical record system (with OLIS to EMR) or Hospital Information System (with OLIS integration), you can access novel coronavirus (COVID-19) lab test results stored in Ontario Laboratories Information System (OLIS) in near real-time.

OLIS HL7 FHIR® Implementation Guide Consumer Query - Overview

The Ontario Laboratories Information System (OLIS) gives authorized health care providers access to lab test orders and results from hospitals, community labs and public health labs. As patients move between hospitals, family physicians, home care and long-term care settings, OLIS makes viewing patients’ current and past test results easier and enables treatment decisions to be made at the point-of-care.

Authorized users across the province can access lab results from OLIS through their clinical viewer (ClinicalConnect™ or ConnectingOntario ClinicalViewer), or their EMR system.


This FHIR – also known as Fast Healthcare Interoperability Resources – specification for OLIS Consumer Query is designed for consumer application use and supports view-only laboratory data. It ensures all information technology systems that retrieve lab data from OLIS can exchange and understand the content through standard HL7 FHIR messages and terminologies.
