Do I Need the Vitamin B12 Test?

You may recommend you have one for a few different reasons, such as:

• You’ve been diagnosed with anemia.
• If your medical condition affects the absorption capacity of B12.
• If your symptoms are linked to low B12 levels.

What happens during a Vitamin B12 Test?

During a Vitamin B12 Test, a lab technician will collect blood from a vein, typically from the inside of your elbow or from the back of your hand. The test will take only a few minutes. The technician:

• Cleans your skin with an antiseptic wipe
• Places an elastic band, or tourniquet, around your upper arm to help the vein swell with blood
• Inserts a needle in your vein and collect a blood sample in one or more vials
• Removes the elastic band
• Covers the area with a bandage to stop any bleeding
• Place a barcode on your blood sample vial and send them to a lab for analysis

A blood test can be slightly uncomfortable. When the needle punctures your skin, you might feel a prick or pinching sensation. Some people also feel faint or light-headed when they see blood. Afterward, you may have minor bruising, but it will clear up within a few days.
