I was told twice that I did not have a thyroid problem, then wound up in the ER where they finally picked it up. I was told at least 2X that I did not have an adrenal problem. When I got a urine test (had to change doctors to get it) instead of a blood test the hypoadrenal problem showed up.
You may not have those problems, but don't assume the blood tests are accurate. If you have symptoms of those problems, get a doctor who will listen (not easy to do) to you and not just look at the blood tests.
