Yeap.. that is the Ft3 = triiodothyronone, free.
Yes the *splat* is computer lingo for multiply.
free t4 1.45 0.61-1.76 - 73%
free t 3 3.3 2.3-4.2 - 52.6 %
You are out of balance. You need to look into your T4 to T3 conversion with an RT3 test. If the RT3 is high, you will need T3 supplementation to balance your levels. It shouldn't take too much for you to get the T3 up and in line.
Have you had a T3 Uptake run? Is it low? If you are an underconverter you also require T3 supplementation. If the RT3 comes back normal you need to look into adrenal fatigue/function. You may be producing too much cortisol.. or not enough ACTH. Either of these scenarios would result in too much cortisol and a suppression of your T4 to T3 conversion.
