The cheapest Vitamin B12 test is DrSays ($24), or Empirical Health ($190) if you want a 100-biomarker bundle that includes Vitamin B12.

How much does a Vitamin B12 test cost at LabCorp?

What is a normal vitamin B12 level?
A serum B12 of roughly 200 to 900 pg/mL is considered normal by most labs. Levels in the low-normal range, around 200 to 400 pg/mL, can still cause symptoms in some people, who may need additional testing such as methylmalonic acid.
Do I need to fast for a B12 test?
Fasting is not generally required. Tell your clinician if you take B12 supplements or biotin, since these can affect the result.
