Blood test results advice please

[BlueLido]

Hello againThanks to those who responded to my last post. I have had time to digest and gone though all my various blood test results and would appreciate any advice.

Background recap, I had a partial thyroidectomy (left side removed due to large nodule) in April 2023. No idea why the nodule grew, thankfully it was benign.

I have been checking through my last blood test results and in particular re vit D, Ferritin and B12. I am due another blood test soon, and want to be prepared for the GP and to ask for a full blood test including vitamins etc.

I am currently on 50mg levothyroxine and have been since November 23) my TSH result history is below as you can see it's variable! I have never been given a T3 T4 blood test.

TSH

Aug 2024. 2.30

June 24. 1.82

March 24. 2.41

Jan 24. 2.11

Oct 23. 0.02 (after being on 100mg levo and feeling awful - hospital said I was over medicated, dropped to 75mg, still felt bad, shaky, nervous and like I was going to have a heart attack, dropped to 50mg levothyroxine. Felt better for a while, but now feeling very tired etc)

July 23. 4.58 (After thyroidectomy)

Apr 23. 2.05 (test prior to thyroidectomy)

Aug 22. 1.75

Sept 19. 2.20

Aug 2012. 2.00

Aug 2007. 1.19

Can anyone tell me what the optimum levels for Vit D, B12 & Ferritin should be?

My latest results are:

Vit D

(I'm also on Letrozole for breast cancer which also can cause osteoporosis)

Jun 2024. 54nmol

Apr 2023 (before thyroidectomy) 55nmol

B12

June 2024. 502ng/l

Sept 2019. 469ng/L

Aug 2012. 451ng/l

Ferritin

March 2024. 198ug/l

June 2024. 84ug/l

For info, I have my blood tests done at 0700hrs, fasting, only water and before taking my levothyroxine . Which I normally take daily at 6am with water, I don't eat or drink any for at least 1 hour after the levo.

Any advice would be appreciated as I'm trying to learn and understand my thyroid condition since my surgery. Unfortunately I think that my thyroid together with the oestrogen blocking medication (letrozole) I take for my breast cancer doesn't help the situation.

As you are all aware GPs aren't too helpful and as long as test results are in 'range' they are unsympathetic.

I have found this forum very helpful, hence my further request for more advice.

Thanking you in advance!

Have you got the ranges for Vit D, B12 and ferritin results as they vary from lab to lab

Vit D is often 50 -200 so you are very near deficient, ideally 100-150 grassrootshealth.net/projec...

Folate is also another important one, any results?

Hi. Thanks for the prompt reply. All I have from the lab re Vit D suggests I'm only just in the adequate range. So feel I need this re-checking as my breast cancer drugs require me to take vit D, but I probably need to take a higher dosage.The Ferritin result is Serum Ferritin which it says the range is between 30-400!! Apparently, unless I'm reading it wrong. Mine is 84.

Then there is a serum folate which is 6. (Note says normal range is 3.89-26.8).

I don't have any ranges re B12.

How much Vit D do you take already? I think many of us find at this time of year around 4000ui works as a maintenance dose but you need to get your levels up in the first place so a loading dose works well here

Ferritin around 100 is considered good but ferritin is a bit fickle as it can show a false high if inflammation is an issue so good to get a full iron panel done too so you really know where your iron levels are

NHS B12 range is often 180-1000 so ideally near top of range and some like to be over

So your folate is pretty dire too, I'd suggest like most of us you'd benefit from a good B Complex to get you up into at least double figures and improve your B12

Thank you for the advice. I currently take 1000. Vit D daily so will up this to 4000. I'll ask GP for full iron bloods to be done. Thanks again.
