You may wish to pick up the microphone you dropped.
LabCorp, for example, is happy to take your money and have you order (and pay for) your own lab tests. Along with third parties using LabCorp and Quest.) Then you can bring in the results to your family physician, and spend 40 minutes browbeating them if you like about your insignificantly elevated white cell count and the normal thyroid level that the naturopath says is actually abnormal and your asymptomatic but positive rheumatoid factor because your feet are achy.
Your blood tests results aren't like the indicators from your car's OBD 2 port; people are complex meat machines with varying genetics (really amazing the more you think about it), and normal value ranges get interpreted as part of a broader clinical picture.
Not only doctors can give tests, but in my experience the more thoughtful ones order fewer tests and barely any "routine" bloodwork (whatever that is), and instead rely on a fairly complex set of heuristics from clinical experience, lengthy education, and a good understanding of underlying normal and abnormal physiology. The $40 I get for listening to your theories about chronic yeast is supposed to pay for a learned professional opinion, and hopefully you'll let me get in a word edgewise about how Panda Express doesn't really constitute 5 servings of vegetables and walking from your parking spaces isn't going to save you from diabetes and hypertension. Instead of having to order more tests to "prove" your potentially, well, crackpot theory. Not you personally of course. Just that guy who thinks reading the Internet and ordering his own blood tests == 7+ years of training.
On the other hand, there is potentially a fair amount of good you could do, if you had to, reading UpToDate and a few basic med school textbooks, and taking a little more care with the idea that a home pregnancy test is in the same ballpark as diagnosing lupus. Oh, and a statistics course — if I had my way, they'd be teaching that in high school instead of trigonometry.
