What a miserable 5mcg of T3 - equal to around 15mcg of levo. This is a link and go to page 80 and on the left-hand side you will see the latest combined recommendation.

Give GP the whole article highlighting the appropriate part:

Usually in the UK, if they add T3 they reduce levo by 50mcg an add 20mcg of T3. 

Your TSH is too high should be 1 or lower, or suppressed for some of us. Your T3 looks on the low side and there's no ranges. We need ranges as labs differ throughout the UK, just to make things a bit more difficult.

Maryloo03,

You are undermedicated to have TSH 3.8 and FT3 below range.  Your FT4 is over range but isn't converting well to T3.  I think your endo needs to increase T3 dose in 10mcg increments until FT3 is 6-7.8.

T3 Free

 4.8 4.0 - 7.8  pmol/L

May I have you opinion on these results ?

Maryloo03,

Low TSH, high FT4 and low FT3 indicates you aren't converting T4 to T3 very well and would probably do better with more T3 added to a slightly reduced dose of Levothyroxine to raise FT3.

I think this set of results is better than the first set you posted but not optimal.
