On Mar. 16, 2022, Roche announced available testing solutions that can identify the SARS-CoV-2 B.1.1.529 variant and differentiate between the Omicron subvariants BA.1, BA.1.1, BA.2, BA.2.2, BA.3 and Delta.

The available research use only tests – VirSNiP SARS-CoV-2 Spike S371L S373P and VirSNiP SARS-CoV-2 Spike S371L S373P 452R – add to the test kits previously developed by Roche and TIB Molbiol for the detection of the recent BA.1 and BA.2, as well as other mutations, present in the novel B.1.1.529 Omicron SARS-CoV-2 variant.
