Tested parameters
- Vitamin B12 is a water-soluble vitamin that is essential for the body. It is one of the components responsible for the formation of red blood cells, which consequently act against anemia. This vitamin is also essential for a healthy brain and nervous system.
Most of the vitamin B12 in our body is found in the bloodstream. With the Vitamin B12 test it is possible to measure the amount of vitamin in our body and thus assess whether there is a vitamin deficiency or not.
Vitamin B12 is obtained through food, especially meat-based diets. This vitamin is released from food by the action of gastric acid and is then combined with a substance called intrinsic factor that promotes its absorption.
