Hi, anyone here deal with elevated b12 levels and can give any helpful info? Like where to find info, or what is considered normal (I'm finding all sorts of answers on the net). I'm reading ranges from 200-600 to 900 to 1500. It's hard to know. Doc said I'm 10% high - but said 1000 is still normal. said i'm 18 points high.

No: I am not taking supplements, eating lots of leafy greens, or veggies. I eat microwavable things. and coffee.

My main concern is what I have read about high levels (not due to supplements or greens) being a pre-cursor in certain cancers. I have several that run in my family, namely that my maternal granma had a type of leukemia which is one of the things listed for elevated b12. My dr thinks i'm being stupid for asking all these questions and says I'm fine.
But with the various on-going symptoms I have, I have to ask at some point 'When is fibromyalgia NOT fibro?'
Thoughts?
Thanks,
Kiya
