I just got my results from st Thomas
Serum b12. 6000
Active b12. 1110
A strange set of results for a vegetarian who's diet meant nutritionally low b12 17 years ago and had 2 top up injections
I am going to have it checked further for auto anti bodies against a binding protein as if this is the case there's no treatment but it rules out tumours /liver/kidney etc
Anyone know anything about this - or had injections which triggered these anti bodies ?
If I had always been like this I would understand , but 19 years ago my b12 was under 100. Maybe the injections ( only 2 so that's long gone) caused an auto immune response . I'm seeing the dr soon so will ask for all b12 since injections to see if it ever dropped down .
If anyone knows anything about this please would you let me know as I'm panicking about more serious illnesses.
Thank you x
