Thyroid hormone not showing in blood test

[Guest guest]

Hi Sheila and all,

Sorry it has been a while since I posted, the temporal arteritis flaring not the

thyroid.

My mum who takes levothyroxine at 200mcg daily has just been to see her gp who

told her that there is no thyroid hormone showing at all in her recent blood

tests and asked if she was sure she had been taking it.

I know for a fact she takes it, first thing every morning before she gets out of

bed.

He has suggested putting the dose up to 250 a day. I feel that this is a

classic sign that it is not converting to T3.

I have told her to ask for Erfa or Armour so we are now waiting to hear from her

doctor.

I should like your opinion on my feelings about this, do you think I am right?

She has recently had cortisone injections on her knees due to sever pain, she is

constantly cold, fatigued and for someone who had a very sharp memory is now

very forgetful. She puts it down to her age, she is 78, but I don't think it is

that as much as the lack of thyroid hormones in her system. Am I correct in

thjinking along those lines?

Many thanks,

Lynne xx
