blood results

[Ivyclose1]

I recently had a blood test (GP) and want help with understanding my results. The test was taken at 9:10am and I stopped my tablets 24 hrs before.

Here are my results.

B12 + FOL + FER

Serum ferritin: 193.0 ug/L (normal range: 30 - 400)

Serum vitamin B12: 1120 ng/L (normal range: 191 - 663)

Serum folate: 7.1 ug/L (normal range: 3.9 - 26.8)

Serum TSH level: 0.42 mu/L (normal range: 0.27 - 4.2)

Thank you for replying to my post.

I have been on 100 mg since I had a TT in March 2015.

I have mostly had the same brand (North Star) but I haven’t been able to get it recently and have been taking activis.

I was thinking to get a private blood test done so thank you for the links.

I haven’t been feeling very well. Lots of joint pain and finding it difficult to walk sometimes.

Activis ……I think you mean Accord (use to be called Activis)

Northstar is just a box - 100mcg and 50mcg are Accord brand inside.

Northstar 25mcg is Teva. But is no longer available from Feb 2023 anymore

Joint pain often low vitamin D and/or low Ft3

I have been taking vitamin D with K2.

As you’ve suggested I’ll get a more thorough blood test, hopefully that’ll give me a better picture of what’s going on.

Thank you once again for your support.

Hi Ivyclose1

NICE guidelines of dosing with levo at 1.6 ug per Kg body weight is a useful guide (and it is just a guide) and lever - you sound hypo but you need a proper test (private) as SlowDragon says. Doctors shouldn’t refuse private labs, they use ranges and are no worse than NHS - in fact they are better as they have more information- However doctors veer away from private tests as they have not been trained to read them and are often out of their depth.

Lived experience 😉👍

Thank you, I think I may be hypo too. I am definitely going to take the advice given by SlowDragon.

I will take a look at the NICE guidelines of dosing.
