Some more of your insights please

Some updated blood results.

Now on 100 Levo been going up in 25 steps with GP. Saw a new endo about a month ago who wanted to do some more tests so here they are

FT4 = 16.9 pmol/l (10.0 to 19.8)

FT3 = 4.2 pmol/l (3.5 to 6.5)

Cortisol = 250 nmol/l ( no range)

TSH 0.78 mU/l (0.35 to 5.5)

ESR 11mm (3 to 9) repeating in a week as above range.

I've managed to nearly double my B12 to 483 ng/l (211 to 911)

I am taking selenium and cod liver oil too.

Endo was thinking of adding some T3. To Levo. Any thoughts?

Thanks in advance.

You need to know the range for the cortisol. Depending on the time of day that could be low or ok. If you think there is a possibility that you might have adrenal issues, which often go hand in hand with thyroid, order the saliva cortisol test from Genova UK - thyroiduk.org.uk/tuk/testin...

How are you feeling? If your endo is willing to add in some T3, then why not try it?

Have you had your iron, folate, ferritin and Vit D levels measured? If not, get them done as they too could be low.


Rosetrees. Have had the recommended suite of test previously that's why I knew the B12 was low but in range and now I've cracked that one. Cortisol was a 9am test but as you say with no reported range it's hard to call. Feeling a little better than a month ago. My biggest concern is my inability to lose weight. As you say - what's the harm in trying it if she is game?!?
