PCR testing: the gold standard
PCR, the most commonly used nucleic acid amplification test (NAAT), is considered the gold standard for COVID-19 diagnosis. Why? Because it is unlikely to return incorrect results.1,2 The advantage of PCR testing is its accuracy, but its disadvantages include its relatively high cost and potentially longer turnaround times. That means we need more than PCR testing alone when there is a surge in cases.
Antigen testing: a fast first step
Antigen testing is a reliable and scalable way to quickly identify active COVID-19 infections at the point of care. Due to evolving variants and unvaccinated populations, antigen testing remains an important tool to limit the spread of COVID-19.
Antibody testing: providing insight
Antibody testing, also known as serology testing, plays an important role in tracking the spread of COVID-19, identifying people who have had an immune response, and understanding personal health. Antibody testing can help inform decisions about resuming daily activities.
