a while ago a post from a lab tech...who claimed that the instruments that test B12 cannot read above 2000.
If that is true, then, a reading of 2000 may not be accurate.
It may in truth be higher.
I really must say, I would NOT discontinue B12 just because of a reading of 1100 (when you know you are taking supplements).
A high reading without supplements may indicate some disease state, and that is all that upper range is good for IMO.
There has never been any reports of B12 toxicity (except for the rare cyano folks who cannot process the cyanide portion of the synthetic version).
