Explain Limitations of COVID-19 Antibody Testing

Point-of-care fingerstick antibody tests for SARS-CoV-2 are entering the scene.

We know these serology tests aim to identify a RECENT or PRIOR infection with COVID-19. The Assure/FaStep COVID-19 IgG/IgM test is the first to have an "emergency use authorization" (EUA) for point-of-care use.

Expect a limited role for antibody testing in the hospital. A positive test doesn't indicate immunity...or allow changes in precautions for COVID-19 (physical distancing, handwashing, mask-wearing, etc).
