You can now get most of your medical lab work done on the cheap through on-line testing services, if you order the labs yourself. After all, if all you need to know is your LDL level, for instance, why pay two to three times as much to have your doctor order the test for you?
One reason, I suppose, is insurance. Insurance won't cover lab work that you order yourself, but it does cover the more expensive labs ordered by your physician. Yet another example of the inefficiencies in our healthcare system, I suppose.
But, for those who with high-deductible plans, self-ordered tests for basic things like cholesterol or lipid levels seems like a no-brainer.
