| | The different "normal" ranges of Serum Vit B12
I wonder there is any difference between labs. The lab I went to has the range of Vit B12 (156-672)
And my B12 rised from 242 to 1598 (156-672) , so I reduced the dose of VB12 supplements.
But I saw some others' labs, they have different normal numbers as (130-900), and the maximum is as high as 900.
