COVID Serological Testing at BCCDC PHL – Early Experience: Tamara Pidduck

TEAM: Inna Sekirov, Tamara Pidduck, Ken Chu, Annie Mak, Mel Krajden,Paul Levett, Muhammad Morshed In early August 2020, BCCDC PHL has started limited clinical testing for COVID-19 serology, of patients falling under the provincial testing guidelines. Since then, 250 patients have been tested, 5 at 1 time point. 214 patients were non-reactive, of these 84 were previously tested by PCR and none were positive; 13 patients were reactive, of these 5 were tested by PCR preserology and were positive; 27 patients had inconclusive results, of these 16 were tested by PCR pre-serology and 2 were positive. These early results provide insights into the relative utility of serological diagnostics and the performance of the selected algorithm.
