HI, I understand that the measurement range for TSH (thyroid stimulating hormone) is 0.4 to 4.0ml. I have had 22 readings over the last 12 years, and they have all been well below 0.4. In fact, they have been <0.05 and the medical printout says "outside reference range".
Within the same period my free T4 readings have always been within the acceptable range (9.0 to 25.0).
I suffer from a range of symptoms including fatigue, brain fog and lack of enthusiasm.
Could anyone provide any insight into these readings. My GP does not understand them.
