Some advice about blood test results please.

Hi I recently posted about the best time to have bloods taken and followed the advice given i.e early morning before food.

I have got a copy of my results but it looks as though everything is well within the normal range so I am now despairing as I feel awful. I am constantly cold, basal temp ranging from 35.0- 35.9 I have been taking it daily for the last 4 weeks.

Average daily temperatures just below or around 36.

Skin as dry as sandpaper, hair brittle and very dry ( hairdresser commented on it when I had it cut a couple of weeks back).

Scalloped tongue, extreme tiredness, brain fog, I could go on.

I should add that I have a strong family history of under active thyroid problems on both maternal and paternal (mother + two of her sisters, fathers side three sisters).

I am 54 and have gone through the menopause.

My cholesterol has been steadily rising , although not measured on this occasion.

Bloods as follows:

serum TSH 2.04mU/L (0.30-5.0)

serum fT4 16.6pmol/L(11.0-23.0)

serum vit B12 534 ng/L (172-1162)

serum folate 7.1 ug/L (4.6- 18.7)

I was supposed to have ferritin levels measured bit D checked and the thyroid antibodies checked in addition but they appear not to have been done, they were on the blood form, I will have to call in to the surgery tomorrow to find out if they forgot to give me that sheet.

I have another appointment with my GP next week, I am not sure how that will go as he was sure that I was exhibiting all the signs of a thyroid condition when I originally saw him a few weeks back.

I am hoping that someone might be able to shed some light on why I feel so rotten.

I have other blood results but all appear about mid range.

Knitywitty, Cholesterol rises in hypothyroid patients. It should drop when you are optimally medicated.

It takes 7/8 days for Levothyroxine to be absorbed and up to 6 weeks for the full impact of the starting dose to be felt and start working...

Thank you as you have probably already guessed I am a bit of a novice.


Knitwitty, 'twas easier for members when the stoopid v down arrow clearly said Edit prior to a site change last year.

Techies don't get it that we don't always get what symbols are for :x

Thanks again for your help, as I am going to see the GP again next week, and if he agreed to give me a trial of levo based on symptoms would it harm me?

I am waiting to see if I have thyroid antibodies as I believe those results may take longer, in addition to Vit D status



It won't harm you just because bloods aren't abnormal and if a trial is offered and helps resolve symptoms it means you do need it.

Bite his arm off if he offers a trial of Levothyroxine but please don't get your hopes up, I think with your unequivocally normal bloods it is unlikely to be offered.


Thanks again, I forgot to mention that I am having a scan on my thyroid next week as the Dr also thought I might be developing a goitre.

I appreciate your comments and keep you updated.


Knitwitty, goitre can develop when the thyroid is struggling to produce thyroid hormone. Your GP sounds proactive and helpful.


Thanks for everything I will post more if I find out anything new, I am shattered and off to bed.

I really appreciate you taking the time to reply.
