Hi, I have an overactive thyroid due to Graves’ disease. I did a blood test this morning and just received the results (private healthcare really is amazing!), I would really appreciate if someone could please help me interpret them:
TSH 0.00 mlU/L (0.3 - 5)
FT3 7.0 pmol/L (3.6 - 10.4)
FT4 23.2 pmol/L (7.5 - 21.1)
My FT3 is under control, yay! It was 46.1 only a month ago, and I was convinced I was going to die of a heart attack any second. Very pleased that’s controlled now.
I’m confused as to why my FT4 is still high? And why do I still have 0 TSH?
I was on a high dose of carbimazole (40mg in the morning, 40mg at night), and am guessing I now need to decrease it to avoid going hypo. Or should I wait until my T4 is normal too, before decreasing the carbimazole? When can I expect my TSH to increase?
Of course I’m going to see my doctor about this, but I’d like to be able to interpret my own results too. Thanks in advance
