Yes! I've actually done this (several companies offer this service now). I think this is great if you have a family pre-disposition to something, or want to regularly check for a specific issue. It's also great because many doctors are hesitant to provide blood tests without a diagnosis. I don't think it has the same use cases as at-home monitoring devices though. To use the example of cholesterol, you can be morbidly, dangerously high in your LDL levels, where doctors will put you on medication that day and warn you to basically stop eating. But you can also just have levels that are high - but where lifestyle change alone is effective. Ideally, you'd want to be able to reflect daily/weekly and adapt. The tighter that feedback loop, the better. Quest charges $70 for a cholesterol panel, which for many, is too high for a regular purchase to build a positive feedback loop. Its probably in the "purchase quarterly" and maybe "monthly" range, but I doubt many would be able or willing to go weekly.
