fT3 and fT4 are good at middle or range.
TSH should be closer to 1.0
TSH=3.67 is a problem
Are you iodine deficient?
Using iodized salt or iodine+selenium in your vitamins?
Iodine deficiency often affects others in the same house.
The best measure of your overall thyroid function is oral body temperature:
- when you first wake up, should be 97..7-97.8F, higher is OK, 93.7 is a problem
- also check for 98.6F/37C mid-afternoon
Is your thyroid sore, enlarged, asymmetrical or lumpy?
Thinning hair [not male pattern baldness]?
Feel cold easily?
Outer eyebrows sparse?
What country are you in?
How is iodine supplied there? Salt, bread, dairy?
Your fT3 should support good body temperatures.
If temperatures are low, then rT3 may be elevated and blocking fT3
