On the hematocrit result, the only thing I know is what I found as follows:

May 26, 2016 - The definition of normal red-blood cell percentage also varies from one medical practice to another. Generally, a normal range is considered to be: For men, 38.8 to 50 percent. For women, 34.9 to 44.5 percent.
Please double check the FT4 and FT3 results. With you taking 200+ mcg of Levo, I would expect the FT4 to be high, not the FT3.
Is TSH the only thyroid related test being done for you?
I should also mention doctors have me on 250mcg of Levothyroxine
