Vitamin B12 (Cobalamin) Test Normal Reference Ranges
| Parameter | Normal Range |
|---|---|
| Normal | 200–900 pg/mL |
Levels in the lower part of the normal range can sometimes still be associated with symptoms, so your doctor may consider your symptoms and additional markers (like homocysteine or methylmalonic acid) even when the result technically falls within range.
