What to expect from a blood test for vitamin B12 deficiency
Short answer
A blood test for vitamin B12 deficiency usually involves a brief blood draw, laboratory analysis, and a review of the result alongside your symptoms and medical history.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

What the result means
The sample may be used to assess vitamin B12 and the appearance of your red blood cells. Your clinician may consider other findings, such as folate status or blood counts, because tiredness, numbness, and changes in concentration can have several causes. A result is interpreted with your symptoms, diet, medicines, and health history rather than in isolation.
What to do before and after
Tell the clinician about supplements, medicines, previous stomach or bowel surgery, and any eating pattern that limits animal products. Follow the laboratory’s instructions about food and drink if you were given them. After the sample, keep pressure on the site for a short while and seek advice if bleeding does not settle. Discuss whether treatment or another test is needed when the report is available.
When to seek care
Seek urgent medical help for new severe weakness, trouble walking, confusion, fainting, chest pain, or difficulty breathing. Arrange prompt clinical review for worsening numbness, balance problems, marked fatigue, or a sore tongue, especially if symptoms are affecting daily activities.
Questions for your doctor
Could my medicines or diet affect the result? Do I need other blood tests to explain my symptoms? When and how will we discuss the report?
