>> there has been some concern even coming out of the fda recently about whether or not these at home tests are less in the face of omicron. we knew at home tests probably had a sensitivity around 85% meaning they would miss 15% to 20% of cases with the false negative. that being said, about i'm confident if we use at home tests in the way they are designed, we use it if a person has symptoms to say, hey, is this the cold, flu, or covid? and we use it if we're doing travel or you're concerned about whether or not you are in a high risk setting or going somewhere where you have vulnerable persons in groups and beginning to test yourself in a serial fashion days before you return home. that's where we know the sensitivity can grow. and i tell people, if you test positive at home, report to your primary care physician that you tested so that we can get this information logged or reported to your local health department.
