Coronavirus Disease 2019 (COVID-19) – Serology

Consistent with O. Reg. 671/92 of the French Language Services Act, laboratory testing information on this page is only available in English because it is scientific or technical in nature and is for use only by qualified health care providers and not by members of the public.

Effective February 1, 2024, PHO’s laboratory will no longer perform COVID-19 serology testing due to limited clinical utility of the test and low submission volumes.

PHO will not accept or test specimens for the detection of SARS-CoV-2 anti-spike (S) IgG or anti-nucleocapsid (N) IgG. Any specimens received on or after February 1, 2024 will be automatically cancelled.

Please note that this change in the PHO test menu does not affect COVID-19 respiratory testing.
