Hi, all.

I've been on generic synthroid for hypothyroid for over 20 years. I don't think the dosage has ever wavered from 50mcg/day. I just had it rechecked and my MD wants to up my dosage to 75mcg/day for the first time. These are the test results:

T3free - 3.02 (was 3.19 7 mos ago)
T4free - 1.2 (was 1.4)
TSH - 6.01 (was 3.11)

Looking at all 3 #s, do you agree that my thryoid function has lessened, or is she just looking at the TSH. I don't understand how these interact, and I know some of you are very knowledgeable about it. I appreciate your help in understanding this.
