Received my recent lab results and I'm a little confused. T3/T4 stayed the same, TSH went up.
After being on 1.25 grains of Nature-throid for a while (maybe a year or so?), here were my labs result on 6/6/14:
TSH: .54 (0.30-5.00 mcIU/mL)
Free T3 2.6 (2.0-4.4 pg/mL)
Free T4 0.76 (0.80-1.80 ng/dL)
After these results, I went on synthetic T3 and T4 (both generic) - started with 56mcg of T4 and 12.5mcg of T3. Eventually lowered to 46mcg of T4 for about 4 weeks and 10mcg of T3. Then had the following labs done on 8/13/14:
TSH 1.90 (0.30-5.00 mcIU/mL)
Free T3 2.7 (2.0-4.4 pg/mL)
Free T4 0.74 (0.80-1.80 ng/dL)
I didn't take my meds the day of the lab. T3 and T4 are essentially the same, but TSH jumped up quite a bit. What gives? When TSH goes up, does this mean my T4 supplementation is too low?
Also, when I originally went on natural desiccated thyroid (maybe about 2.5 yrs ago), my labs were actually all in range. Why is my T4 low now? Is it because the thyroid meds temporarily suppress the thyroid, and that if I went off the meds altogether, my thyroid would jump back up to speed in a couple days?
