Mayo Clinic Laboratories is carefully monitoring the emergence of two new variants of SARS-CoV-2 ― the virus that causes COVID-19 ― in the U.S. One variant is from the U.K. and one variant is from South Africa.

At this time, the assays performed at Mayo Clinic Laboratories (Test ID: COVOO) will detect currently known variants. We will continue to monitor circulating strains to ensure testing accuracy.
