Vitamin B12 is a water-soluble vitamin that is responsible for the metabolism of every cell of the human body. It is also called cobalamin. It helps your body make DNA, which is the genetic material in every cell. A Vitamin B12 test is done to check the amount of Vitamin B12 in the blood or urine, and consequently, to check the balance of this vitamin in the body.
The primary purpose of the Vitamin B12 test is to find the level of Vitamin B12 in your blood. The report may indicate a normal, low or high Vitamin B12 level. The report is normally accompanied by the normal ranges and the level that you have in your report can be compared to the normal ranges and then accordingly you can take further measures.

Are there some risks involved in getting a Vitamin B12 test done?
For your Vitamin B12 test you are just submitting your blood sample and your urine sample (or just one of these). There may be excessive bleeding when the blood is being drawn from your arm's vein, but it will be immediately taken care of by the person drawing the blood. Sometimes multiple punctures need to be made to locate the right vein. A slight hematoma may develop (blood buildup under the skin). People who are sensitive about seeing blood may feel like fainting or light-hearted.
