"The problem that some patients do not have tests performed when they genuinely need them is also real but probably of lesser magnitude." Anecdotally speaking, I have seen many instances when testing was procrastinated only to reveal a chronic condition (hypothyroidism, pre-diabetic sugar levels) needing immediate attention sometimes with medications.

I am genetically disposed to hyperlipidemia and like to watch my cholesterol level as a tangible indicator/reward for my life style changes.

"Better financing and organization of health care and, perhaps, reduction of the profit margin could markedly decrease testing cost, even if very old (but appropriately validated) diagnostic technologies are used."

Reduced pricing was a hype created by Theranos. When we started working in this area, we found that if one is willing to pay out of pocket some labs will offer pricing very close to Theranos.
