My doc has to note to the lab, that I take a B12 suppliment, or my tests come back as a 'flag' that my levels are 'abnormally' high.
As a matter of fact, my levels, while taking B12 suppliment-
are between 1200 & 1500. Not excessively high, but higher than 'normal'.

And who is it, Rose? That has the B-12 site? States that people with PN should have higher levels of B-12...cause for many of us what's a normal healthy level is higher than what is considered "normal values" for people without PN.
