B12 levels cannot become high, if you are not absorbing.
They can become high if your kidneys are not excreting it.
So some studies show high B12 levels when no supplements are taken, as kidney related.
High levels of B12 with no supplements, may occur with some leukemias, or some intestinal dysbioses (infections with certain B12 forming organisms). These are pretty uncommon and not usually found with a B12 screen.
