Recently had an active B12 test, results are:
41 (range pmol/L 25.1 - 165.0)
Also, I had a recent B12 serum test done, result was:
556 (range 180 - 900)
Personally, I think these are low and that I need treating. I have a very strong family history of pernicious anaemia including many immediate relatives. I am also hypothyroid and hypoparathyroid. In Japan and Europe people are treated with B12 is their serum is 550. I am pretty close to that and would be treated if didn't live in the UK. I also read that with people who are hypo, their B12 needs to be in the upper end of the range or elevated. I am neither of these - am in the middle. I am also vegetarian so not getting any B12 sources from food. I sent off for my medical notes and 5 yrs ago I had a B12 serum of 1550. I had taken B12 supplements in the past which I bought in health food shops.
I am aware that the injections cost £40 - £100. GP wont prescribe. If anyone knows where else these can be obtained, please PM me. Am only able to pay for the cost of the supplement, not a private consultation. The other thing is, would I have to inject myself - as I am needle phobic, usually faint ect on sight of blood, some blood tests ect.
Please feed back
