My maths is dreadful!
Can someone tell me what equation to use to work our percentage through range.
I’d really like to know for my T4 before I go and see the dr again to request a dose increase. It looks like my T4 is just under half way through but I’d like to be able to calculate it properly.
Serum free T4 level 16.8 pmol/L [11.0 – 23.0]
Serum TSH level 1.6 mU/L [0.27 - 4.5]
