Latest bloods result - what does it mean?

Hi all, I have my latest thyroid blood results & wanted to see if anyone could shed some light on them?

I was diagnosed as hypo last November, 2012. In August 2013 I went & saw dr skinner in Birmingham, who is amazing and wanted to increase my dose. I asked for Armour and he, almost reluctantly, gave it to me . I'm now on 25mg levothyroxine and 2 grains of Armour. Initially I started to feel good but went back down. Anyhoo, I've been on the armour for almost 2 months (gradually increased to 2, soon to be 3 grains.) my latest results are;


Serum free T3 level 5.6 pmol/L

(3.50 - 6.50pmol/L)

Serum free T4 level 16.1 pmol/L (10.30 - 22.70pmol/L)

Serum TSH level <0.03 mu/L

(0.35 - 5.50mu/L)

My previous bloods were;


Serum TSH level 6.71

T4 10.4


TSH level 2.97

Any advice would be great

Thanks for reading!

Hi Sarah

Can you also put the ranges of your blood tests (the figures are in brackets) as labs differ throughout the country and it will help members to comment.


Thank you, yes, I've added them now.


Bumping up as I've had no replies. Hoping someone has some wise words. Xxx
