Blood Results advice

Blood Results advice

I'm 17 and lately I've had symptoms such as fatigue, lack of motivation, loss of appetite, dry skin, nausea and when I went to my GP with laryngitis he ordered blood tests. Came back elevated TSH and also vitamin D deficiency, which I am now taking supplements for. My GP says he's not worried about the high TSH but provided a letter of referral to hospital to get more bloods done due to my symptoms. Above is a section of the blood results.

KirstyC11 Well, your TSH is over range and your FT4 half way through it's range. Normally a GP would retest in a few months to see if your TSH is still rising.

Your vitamins and minerals aren't particularly good.

B12 is low in range, optimal level is top of the range, even 900-1000. Supplementing would be a good idea but you might want to run it by your GP before doing anything about it yourself. Come backnand let us know what he says - which will probably be that it's in range so it's fine - if he wont do anything we can suggest what to get.

Ask your GP to look at your iron panel too. Your Ferritin is very low in it's range which suggests supplementing with iron tablets. Ferritin should be half way through it's range with an absolute minimum of 70 for thyroid hormone (and that's our own thyroid hormone as well as replacement hormone) to work. Low ferritin can cause fatigue and hair loss amongst other things.

As you are taking Vit D supplements, are these prescribed and if so what are they and what dose? If prescribed then you may be getting too small a dose so let us know what your level is. When taking Vit D we also need it's very important co-factors K2-MK7 and magnesium. Vit D aids absorption of calcium from food and K2 directs the calcium to bones and teeth rather than arteries and soft tissues. If you need suggestions for these supplements just ask.


Wanted to thank you for posting as the reply you've had has already made me think I've just posted my own bloods for help.

Good luck - the little I know is that your TSH is out and that other GPs range is smaller so often people feel bad over 2 and normal is under 3 so 5+ sounds out to me but feel free to ignore me as I am new to all of this as well


With a high TSH like that, and a mid-range FT4, it probably means that you're not converting very well, and your FT3 is low. Possibly due to your low nutrients.

What you really need is the FT4 and the FT3 tested at the same time, to see how well you're converting.

Of course your doctor isn't worried about your high TSH, he knows very little about thyroid! But I think he might be more concerned, if it were his TSH!

your B12 may or may not be a problem - the serum ~B12 test isn't a good guide.

Important not to supplement if you want to investigate that further as supplementation affects results and makes getting a diagnosis really difficult.

Suggest that you explore thyroid and vit D before doing anything about the possibility that B12 might also be a problem.

Lots of information and support on B12 available on the PAS forum
