Hi - back from the docs with results in hand! TSH level 5.78 (range 0.35-5.5) FT4 11.1 (range 11-23) comment is 'high' but also MCH (mean corpuscular haemoglobin) is 32.3 (range (27 - 31) and comment is 'high' . I see from googling (!) the 2 are linked? Doc wants to leave me a month and test again - what are your thoughts?
