Laval, Quebec, May 17, 2021 –
“Roche Diagnostics Canada values the collaboration with Canadian Blood Services, which includes the use of our Elecsys® Anti-SARS-CoV-2-S and Elecsys® Anti-SARS-CoV-2 serology tests and showcase Roche’s increasing contribution to the fight against the pandemic,” said Michele D’Elia, Director, Medical and Scientific Affairs at Roche Diagnostics. “We are very pleased with Canadian Blood Services’ decision to trust the innovation and quality of our testing solutions and we trust their seroprevalence study will obtain results that can be translated into positive outcomes for Canadians.”
Canadian Blood Services has regularly been testing blood donor samples for antibodies to SARS-CoV-2 since last summer, as part of a long-term project funded by the COVID-19 Immunity Task Force (CITF), which is, among other mandates, leading a Canada-wide effort to help determine the extent of SARS-CoV-2 infection in Canada. With this partnership, Canadian Blood Services expects to obtain more data to inform the public health officials across the country, through the CITF, in the following areas:
Immunity in Canadians by measuring the level of antibodies developed by COVID-19 vaccines and natural infection
Seroprevalence of the virus in younger populations
Seroprevalence rates in Canadians
Disparity in seroprevalence rates
Relation between socioeconomic factors and seroprevalence rates
Vaccination strategies, such as which populations should be prioritized to receive the vaccine
Speed of propagation of the virus
“Canadian Blood Services has been able to respond with agility in the constantly changing context of the COVID-19 pandemic. This partnership is an important next step in our ongoing commitment to provide serosurveillance data,” said Dr. Sheila O’Brien, Associate Director of Epidemiology & Surveillance at Canadian Blood Services.
Roche and Canadian Blood Services have worked together for over 20 years to bring innovation in blood screening methods. In 2017, the blood operator implemented Roche's cobas® 8800 Systems with pre-analytics that improves staffing efficiency and offers flexibility to meet changing needs and productivity improvement. It also just started serology testing on Roche's Systems cobas immunoanalyzers, which will be used to screen donations with Anti-HBc II, HBsAg II, Anti-HCV II, HIV Duo, HTLV I/II and Chagas tests. Canadian Blood Services and Roche are partners committed to best patient safety and best patient care.
In Canada, Roche Diagnostics is diligently offering its COVID-19 solutions to laboratories and taking the necessary measures to help reduce the consequences of the pandemic. The company praises the efforts of healthcare providers and frontline workers in communities across Canada.
