Quote from Chrisgj:Here are the test results, please tell me what you think (too mind boggling, but I want to understand). I was diagnosed secondary hypo.
TSH 1.262 uIU/ml (0.350-5.500)
Thyroxine 11.0 micrograms/dl (4.5-12.0)
T3 Uptake 33% (24-39)
Free thyroxine index 3.6 (1.2-4.9)
Triiodothyronine, Free, Serum 3.0 Pg/ml (2.3-4.2
T4, Free (direct) 1.46 ng/dl (0.61 -1.76)
[FONT=Comic Sans MS]Hi Chris..........let me try.
Your TSH needs to be somewhat ignored. Your Thyroxine needs to be ignored, your T3 Uptake needs to be ignored, and your Free thyroxine needs to be ignored.
Okay, that leaves you with the only ones that need to concern you:
Free T3 (triiodothyronine, Free, serum). It should be in the upper third of normal values, like around 3.5.
Free T4, which read around where it's at, 1.46 to 1.65, or so.
It's all in how you feel at those numbers. Do you feel well, with a clear head?
If not, your FT4 is raised by taking T4 (Synthroid and such).
If feeling foggy, then your FT3 needs to go up with more T3 (Cytomel and such).
Or.....you could take Armour thyroid which has both T4 (80%) and T3 (20%), and add Cytomel (all T3) if later you find that it needs more tweaking.
Don't forget.....T4 requires 6 - 8 weeks to raise to the level of the dose you're taking before more lab work can be done, and T3 only requires 2 weeks to raise to the dose level you're taking!
Remember that only the FT3 and FT4 will give you the readings you require to adjust your doses.... :)
Good luck and keep us posted! :wave: [/FONT]
