Blood labs taken a week ago. Anyone who knows more than I please decode and advise?

TSH - Ref Range: 0.40-4.50 (mIU/L) 1.81

T4 Free - Ref Range: 0.8-1.8 (ng/dL) 1.0

T3 Free - Ref Range: 2.3-4.2 (pg/mL) 2.7

I'm not sure, but seems the tiniest bit better than last labs (6 months ago) but still not good.

Your Free T4 is 20% of the way through the reference range.

Your Free T3 is 21% of the way through the reference range.

Many people only feel well with Free T4 in the top quarter of the reference range, and Free T3 in the top third or top quarter of the reference range.

If you get your Free T4 levels higher then you have to watch what happens to your Free T3. If it doesn't rise as much as you would hope then you have conversion problems too, but it isn't really possible to say at the moment.

I've written this on the assumption you are taking levothyroxine. But even if you are taking NDT it doesn't really matter. In either case you are very under-medicated, in my opinion.

I am taking WP thyroid in the amount of 0.75 gr. I was switched from Armour and also increased from 0.5 gr to the now 0.75. I had to beg my doctor to consider that increase which made a smidgen of an improvement. I am definitely considering begging him to increase my dosage to 1gr when I go to see him week after next. Why is it that doctors are so afraid to make a change if labs are anywhere within reference boundaries, regardless of WHERE in those boundaries? My doc has me to fill out a paper concerning my symptoms at every visit, then totally ignores them! I am thinking, (if I have the guts), about instead of filling out that form, writing on it that I will not do so if symptoms referenced are not considered.

I imagine your doctor thinks that raising your dosage will suppress your TSH. And doctors think that a suppressed TSH means you are hyperthyroid and are likely to develop bones which crumble (osteoporosis) and heart problems that will make you drop dead within days. (They don't care about Free T4 and Free T3, only TSH.) The fact that there is recent evidence saying otherwise makes no difference - doctors have been brainwashed and that is the end of the matter.
