The Ontario Laboratories Information System (OLIS) is a data repository for lab test orders and results from commercial and hospital laboratories including the Public Health Ontario Laboratories.
OLIS has been integrated with the integrated Public Health Information System (iPHIS) and the Public Health Case and Contact Management Solution (CCM) to provide health units access to SARS-CoV-2 test results among local residents. Not all laboratories performing SARS-CoV-2 tests are reporting through the OLIS system.
Local residents are defined through OLIS based on the postal code associated with a valid health card number, or by the postal code of an address provided at the time of testing. Only results associated with a valid health card number and local address are available to health units through the OLIS system.
Reported data on testing for COVID-19 provided through OLIS does not represent all COVID-19 tests completed locally, or all COVID-19 tests completed on local residents.
