If your PCP checks a CBC and a CMP, all of these metrics are there (which virtually 99% of PCP’s do yearly). Lipid panels are regularly checked, A1c is checked periodically if you have a diabetes risk, usually every 1 to 3 years based off USPSTF guidelines.

The only thing that is not regularly checked is a vitamin D level.

So unless you go to some quack MD who orders nothing (which is usually the exact opposite of what quack MDs do) you’re wrong.
