Are COVID tests capable of detecting the Delta and Omicron variants?

Frequent COVID testing can identify both the Delta and Omicron variants of the coronavirus, allowing you to decide whether you have it. They cannot tell which variant is responsible, though. This would need genome sequencing, a different technique from standard virus testing that not all labs can perform. Sequencing is a somewhat rare procedure that can cost up to $100 for each test. Because the therapy is identical for all variants, knowing whether a mutation generated the illness is not clinically valuable for an individual patient.
