A vitamin B12 deficiency test measures the level of vitamin B12 in your blood. It is ordered when you have symptoms like fatigue, tingling in hands or feet, or when a clinician suspects poor absorption or a diet low in B12.

What it measures

  • Vitamin B12 (cobalamin) — The main measurement of B12 in your blood.
  • Folate (folic acid) — Often checked because low folate can cause similar symptoms.
  • Methylmalonic acid (MMA) — A substance that rises when B12 is low; helps confirm deficiency.
  • Homocysteine — Another marker that can be elevated with low B12.
  • Complete blood count (CBC) — Checks for anemia, which can be caused by low B12.

Who it is for

A clinician may order this test if you have symptoms of deficiency, a diet low in animal products, or conditions that affect absorption like celiac disease or gastric surgery.

Preparation

Usually no fasting is required. Tell your clinician about any supplements you take, as they can affect results.

Results and what they mean

Results are reported as numbers with a reference range. Your clinician interprets them along with your symptoms and history. This is general information, not medical advice.
