The Vitamin B12 Test measures the level of vitamin B12 in your blood. Vitamin B12 is an essential nutrient and is necessary for producing and maintaining nerve and red blood cells, supporting the nervous system, and helping to create DNA, the basis of all cells. Vitamin B12 must be supplied by the diet or through supplementation because the body is not able to produce it. Vitamin B12 deficiency (low levels of vitamin B12) may be due to limited dietary intake, poor absorption, advanced age, certain medical conditions, or some medications. Low levels of vitamin B12 can lead to anemia, nervous system conditions, and a variety of health issues. This test can help determine whether you have a vitamin B12 deficiency.
What is tested?
Our Vitamin B12 Test measures the level of vitamin B12 in your blood. Vitamin B12 is absorbed in the small intestines and then makes its way to the blood and cells. The body also stores vitamin B12 in the liver for future use. Vitamin B12 is essential in supporting the nervous system, making red blood cells, and creating DNA (the genetic material present in our cells). Vitamin B12 must be supplied by the diet or supplementation because the body is not able to produce it independently. It is naturally found in animal proteins, such as red meat, fish, poultry, eggs, and dairy. Plant foods are not a reliable source of vitamin B12 unless they are fortified. Low levels of vitamin B12 may occur if you do not consume enough vitamin B12 or the body does not store or absorb enough of the vitamin. People who are deficient in vitamin B12 may or may not have any symptoms of anemia (a condition in which your body does not have enough healthy red cells to carry oxygen to your body’s tissues) or nerve damage. Early detection is important to prevent irreversible damage over time, especially to the nervous system.
Signs & Symptoms
People with low levels of vitamin B12 may not have any symptoms or may have symptoms of anemia or nerve damage. General symptoms related to anemia and nerve damage include fatigue, weakness, difficulty concentrating, depression, numbness or tingling in the hands and feet, headaches, moodiness, and gastrointestinal symptoms.
