Order Vitamin B12 Deficiency TestVitamin B12 is a water-soluble vitamin that supports red blood cell formation, neurological function, and DNA synthesis. Because the body does not produce it, B12 must be obtained through diet or supplementation. A deficiency can develop gradually and may produce subtle symptoms that are easy to overlook.
About Vitamin B12 Deficiency Test in Fallbrook
This blood test measures the concentration of vitamin B12 in the bloodstream to help identify a deficiency.
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 prior gastrointestinal surgery, can impair absorption even when dietary intake is adequate.
People following a vegan or vegetarian diet, older adults, and those with digestive disorders are among the groups at higher risk for low B12. Certain medications, including proton pump inhibitors and metformin, may also reduce B12 levels over time.
Symptoms of deficiency can include fatigue, weakness, tingling in the hands and feet, difficulty concentrating, and mood changes. Because these signs overlap with many other conditions, laboratory testing is used to confirm whether B12 is low and to guide further evaluation.
