I am pretty sure my doctors are a tad simple.
I mean, I'm no doctor, but I can see my levels have increased quite a lot in a year, especially since I don't take supplements plus I am a vegetarian so B12 levels are generally lower.
It says could be caused by my loading B12 injections which I had due to my low levels FIVE YEARS AGO so common sense would tell me that the drastic increase isn't anything to do with something I've not had for 5 years.
I have no idea what it is and although clearly says 'abnormal' - they don't seem to have a problem, yet my Vit D levels were down a tiny amount (probably because winter) and I got a text saying go buy supplements, but a B12 that has almost doubled and is over normal limits isn't a problem?
Anyone else had B12 levels of over 1300?
