The check precisely recognized 91.2% of constructive samples and 99.3% of destructive samples, so it is rather delicate and particular.

A destructive end result means individuals are seemingly actually destructive, as a result of the check had a 99.6% destructive predictive worth, the FDA notes. Individuals who check constructive ought to think about using a lab check to substantiate the end result. In a separate research particular to the Omicron variant, the check’s efficiency was comparable.
