These are my most recent test results.
Component Your result Standard range Units
T4 FREE 1.07 0.6-1.7 NG/DL
T3 121.1 60-181 NG/DL
TSH,BLD,QN 1.990 0.320-5.500 MIU/ML
Generally people seem to feel best with a FT4 of about 1.3-1.4 ng/dl. So I would consider your result to be low.
That looks like a total T3 instead of free unfortunately.
Your TSH is still between 1-2...but just barely.
I would bet big bucks that your FT3 would be low as well if you got it tested. I would also bet with your sensitivity to temp and Reynaud's that you also have HPA axis dysfunction causing faltering cortisol production. This may impact your ability to tolerate thyroid hormone so it is important to test and address it first.
Low iron is another cause of inability to tolerate or benefit from thyroid hormone. Optimal serum iron levels are generally considered to be 100-110 with a %sat of 35-45% and TIBC/UIBC well above the bottom of the range which indicates the ability to safely store iron.
It would also be worthwhile to try to figure out if your hypothyroidism is caused by an autoimmune process such as Hashimoto's or if it is a result of chronic illness. The former is often readily responsive to thyroid meds while the latter may not be. Thyroid antibodies (TgAB and anti TPOAb) can help to sort this out.
Either way, if the FT3 is also low, I would ask my open minded progressive doctor for a trial of thyroid meds (most likely a T4/T3 blend rather than simply T4) and see if titrating up to an optimal dose (usually 3-5 grains of natural desiccated thyroid) helps you feel better or not.
If it turns out that pathogens are responsible for your hypothyroidism as opposed to an autoimmune disease, treating those can also go a long way towards resolving the problem.
