Further to my post yesterday, I now have the ratio. According to STTM it should be over 20!
Given that maths isn't my strong point, perhaps my calculations should be checked:
FT3: 4.17 pmol/L
rT3: 18 ug/ L
So, the actual rT3 result is above 14 and this, according to STTM, is excessive.
The ratio is 0.2 and should be over 20.
The result fits with a low normal FT4 reading of 15.59 (12-22).
These results are one of many I posted yesterday - please see healthunlocked.com/thyroidu...
for further info.
I would really appreciate help with this as it does look as though I finally have some clues as to what may be going on - and that there may be an underlying cause to all my symptoms.
