About this test

Vitamin B12 is essential for healthy red blood cells and nerve function. A normal vitamin B12 level is about 200–900 pg/mL.

Low B12 levels (below 200 pg/mL) are common in vegetarians, people taking metformin or antacids, and those with pernicious anemia or gut disorders. Vitamin B12 deficiency symptoms include fatigue, anemia, tingling, numbness, memory loss, and poor balance.

High B12 levels, without supplements, may signal liver, kidney, or blood disorders.

Treatment includes B12 injections or high-dose oral supplements. Test early to prevent permanent nerve damage.

Questions about this test

When should I get the B12 Level test?

You should get a vitamin B12 test if you have fatigue, weakness, pale skin, tingling or numbness in the hands and feet, memory problems, or a sore tongue. It is also recommended for vegetarians, the elderly, pregnant women, people with digestive disorders, and those taking metformin or antacids long-term.

How should I prepare for the B12 Level test?

Fasting for 8–12 hours is usually recommended before a vitamin B12 test, and you may drink water during this time. Inform your doctor about any B12, B-complex, or multivitamin supplements or B12 injections, as you may be advised to stop them before testing. Also mention medicines like metformin or antacids. Follow your lab's instructions.

Do I require fasting for the B12 Level test?

Yes, fasting is usually recommended for a vitamin B12 test. You should fast for 8–12 hours before giving your sample, though drinking water is allowed. Inform your doctor about any B12 supplements or injections you take, as they can raise your levels and affect the results.
