I have been hypothyroid for 8 years now and on synthroid until 3 months ago. 3 months ago I switched over to Armour Thyroid.
My newest labs came in
On 120 mg of Armour for 3 months
TSH 0.00 (0.34-4.82)
Free T4 0.57 (0.59-1.17)
Free T3 3.0 (2.0-4.4)
My labs 3 months ago on synthroid were
TSH 2.61 (0.34-4.82)
Free T4 0.69 (0.59-1.17)
Free T3 2.1 (2.0-4.4)
I am new to reading my labs, but what I see in my current labs is that my Free t4 and t3 could be higher. I have read that we should not put too much into the TSH reading, so a TSH of 0 should not be looked at fully.
The dr is trying to say that because my TSH has had such a dramatic decrease and is now 0 that my meds need to be lowered. He wants to lower my dosage from 120 mg to 90 mg. Am I correct in my hesitation to lower meds or is a 0.00 TSH bad?
