Hypothyroidism Diagnosis: Not sure what to do at this point

@rneedham1 I was just re-reading through this and the thought occurred to me, are you by any chance taking biotin? If so it could explain the unusual difference in your tests. Biotin does not affect your thyroid but it can cause incorrect results in the TSH tests. If you are having a TSH test my endocrinologist to stop taking biotin a few days beforehand.
