Emerging SARS-CoV-2 variants and the COVID-19 vaccination campaigns have increased complexity for COVID-19 testing.

A few months ago, concerns about COVID-19 diagnostic testing were mostly a matter of test availability and whether the results would be returned in soon enough to make a public health difference.
Now, emerging SARS-CoV-2 variants and the COVID-19 vaccination campaigns have increased complexity for COVID-19 testing. Many wonder if the tests will accurately diagnose infection with a variant strain of SARS-CoV-2, and whether vaccination will lead to inaccurate results with a diagnostic or serological test. The good news is that most diagnostic tests now in use will remain accurate with the variant strains, and vaccination should not interfere with diagnostic or antibody tests. However, maintaining diagnostic test accuracy is yet another reason why surveillance for new variants of SARS-CoV-2
