Order Vitamin B12 Deficiency TestVitamin B12 is a water-soluble nutrient that the body relies on for red blood cell formation, neurological function, and DNA synthesis. Because the body does not produce B12 on its own, it must be obtained through diet or supplementation. A deficiency can develop gradually and may produce subtle symptoms that are easy to overlook. The Vitamin B12 Deficiency Test measures the amount of B12 circulating in the blood to help identify whether a deficiency is present.
About Vitamin B12 Deficiency Test in Gurnee
Understanding the role of vitamin B12 in the body provides context for why this test is ordered and what the results can indicate.
Vitamin B12 is absorbed in the small intestine with the help of intrinsic factor, a protein produced by the stomach. Conditions that interfere with this process, such as pernicious anemia, celiac disease, Crohn's disease, or certain gastric surgeries, can reduce absorption even when dietary intake is adequate. Strict vegetarian and vegan diets may also lead to low levels if fortified foods or supplements are not consumed.
Symptoms of a B12 deficiency can include fatigue, weakness, tingling or numbness in the hands and feet, difficulty concentrating, and a sore tongue. Because these symptoms overlap with many other conditions, laboratory testing is often necessary to confirm whether B12 is the underlying cause.
The Vitamin B12 Deficiency Test is a blood draw that quantifies the concentration of B12 in the serum. Results are typically available within one to three business days. Preparation instructions should be followed as provided by the laboratory performing the draw.
