Re: Low platelets and fatigue
I have low thyroid as well as low platelets due to two separate autoimmune diseases. I'm quite well-read on thyroid diseases and can tell you that the TSH test alone isn't sufficient for diagnosis. The American Assn. of Clinical Endos issued a 2002 statement that the reference range of "normal" is too broad and misses many cases of hypothyroidism.
If your TSH was higher than 2, you should also have a free T4 test (at least). If free T4 is below the mid-point of its range, that would strongly suggest you're hypothyroid and might account for your fatigue. Just so you know.
