Normal means nothing or very little when vitamins are tested at
MD labs.
If that satisfies you, so be it. But you could still be very low
in B12 and not even know it.
The new lab ranges do not exist in US. But some medical CE sites now recommend the newest low normal at 400 US units.
If you test at 220...for example, you would be severely low in B12. Your doctor would call your test "normal" because the lab does not "flag" it for him to consider. Many doctors do not even know the new guidelines.
Here is the American Association of Family Physicians article from 2003 on this subject:

One of the tasks of this forum is to point out to patients, that just because they had a "test" and the doctor said "normal" that just might not be accurate anymore!
