In brief: Often
It is used for many indications, often to check for causes of low blood count (anemia) or nutrition malabsorption.

In brief: Not a routine test.
We screen for B12 deficit when pts have anemia, or had gastric surgery or when they have neuropathies or dementia.
Also during malabsorption or malnutrition. It is not a routine screening test.
