Vitamin B 12 Test Overview

Vitamin B 12 test meashures Vitamin B12 in the blood of the patient. Vegetarians are at risk of deficiency of Vitamin B12 as there are no plant sources of Vitamin B12. Vitamin B12 is important for formation of blood cells, brain health, energy production during carbohydrate, fat and protein metabolism and is essential for proper nerve functioning. Vitamin B12 and folate are the two vitamins that must be supplied in the diet as they cannot be produced in the body. 
Vitamin B12 deficiency can occur due to dietary issues and antibodies towards Intrinsic factor which helps in absorption of Vitamin B12

Test Overview

This examination measures the patient's blood levels of vitamin B12. Since there are no plant-based sources of vitamin B12, vegetarians are at peril of a deficit. Blood cell generation, cognitive performance, energy production during the metabolism of carbohydrates, fats, and proteins, and healthy nerve function all depend on vitamin B12. The other vitamins that need to be given through diet are folate and vitamin B12 as the body cannot generate them.

Dietary problems and antibodies against the intrinsic factor, which aids in vitamin B12 absorption, can cause vitamin B12 insufficiency.

Another application for cyanocobalamin is as a component of a diagnostic test. This cyanocobalamin test is used to evaluate a patient's capacity for vitamin B12 absorption. The purpose of the cyanocobalamin test is to determine whether a person's ability to absorb vitamin B12 is deficient in any way. Although the patients' blood tests indicate they have a vitamin B12 deficiency, some people may be getting enough vitamin B12 through their diet.
