8Understanding Test Results
The results of a vitamin B12 level test might be:
– Low: When vitamin B12 levels are below 200 ng/mL. This indicates an overactive thyroid, pernicious anemia, or a deficiency of vitamin B12.
– Normal: When vitamin B12 levels are from 200 to 900 ng/mL.
– High: When vitamin B12 levels are over 900 n/mL. This indicates several types of leukemia, diabetes, or kidney or liver issues.
The results of the test can vary a lot, depending on the lab. Thus, it is necessary to discuss it carefully with your doctor. [8]
