What the world needs

and what I would invent if I were at all an inventor, is a gauge, a scale, a measuring device of some kind, that could tell a parent, by means of a retinal scan or a finger prick or a puff of breath, whether a child is sick enough to stay home from school. And I don't want any gray areas, no scale from 1 to 10 because if the child gets a 5 then what? No, I want a red light (child is too ill, will not be able to make it through the day) or a green light (child is fine regardless of her own self-assessment, put her on the bus).

Why is this not a thing?

I would pay good money for that!
