What Is a Vitamin B12 Test?
A Vitamin B12 Test measures the amount of Vitamin B12 in your blood.
Vitamin B12 is essential for healthy nerve function, DNA production, and red blood cell formation.
Doctors commonly recommend this test to diagnose Vitamin B12 deficiency and certain types of anemia.
Why Is Vitamin B12 Important?
Vitamin B12 plays a vital role in maintaining healthy nerves, producing red blood cells, and supporting brain function.
Low Vitamin B12 levels may lead to fatigue, weakness, numbness, memory problems, and anemia.
Early detection helps prevent long-term neurological complications.
Symptoms of Vitamin B12 Deficiency
Common symptoms include:
- Fatigue
- Weakness
- Tingling or numbness
- Difficulty walking
- Pale skin
- Memory loss
- Depression
- Shortness of breath
Some people may have deficiency without obvious symptoms.
Who Should Get Tested?
Vitamin B12 testing is recommended for older adults, vegetarians, vegans, people with digestive disorders, patients taking long-term metformin or acid-reducing medicines, and anyone experiencing symptoms of Vitamin B12 deficiency.
Vitamin B12 Normal Range
Typical reference ranges are:
- Above 200 pg/mL — Normal
- 150–200 pg/mL — Borderline
- Below 150 pg/mL — Deficient
Results should always be interpreted by your healthcare provider.
Understanding Test Results
Low Vitamin B12 levels may indicate dietary deficiency, poor absorption, pernicious anemia, or gastrointestinal disorders.
Doctors may recommend additional tests such as folate, CBC, or methylmalonic acid depending on your condition.

Benefits include:
- Better energy
