PREPARATION: No fasting or other special preparation is needed for this test.
What does this test do?
This test determines the concentration of vitamin B12 circulating in the bloodstream. Vitamin B12 (also known as cyanocobalamin) is an important precursor in red blood cell production. Like folate, a lack of Vitamin B12 also causes macrocytic anemia. Vitamin B12 is not found in vegetables; instead it is contained in animal products such as meat, shellfish, milk, cheese, and eggs.
What do the results mean?
Low levels of Vitamin B12 are rarely caused by dietary deficiencies (except in vegans who do not eat any animal products), but more commonly result from absorption problems within the digestive tract (a condition called pernicious anemia).
