A lipid panel is one of the most basic blood tests in modern medicine. Doctors use it to measure cholesterol levels in their patients, probably millions of times each year.
This is not a procedure where some hospitals are really great at lipid panels and some are terrible. There's just not space for quality variation: you are running blood through a machine and pressing buttons. That's it.
And that all makes it a bit baffling why, in California, a lipid panel can cost anywhere between $10 and $10,000. In either case, it is the exact same test.
