Order Vitamin B12 Deficiency TestVitamin B12 is a water-soluble vitamin that the body relies on for red blood cell formation, neurological function, and DNA synthesis.

About Vitamin B12 Deficiency Test in Santee
The Vitamin B12 Deficiency Test measures the concentration of vitamin B12 in the blood to help identify a deficiency.
Vitamin B12, also called cobalamin, is obtained primarily from animal-derived foods and is absorbed in the digestive tract with the help of intrinsic factor, a protein produced by the stomach. When intake is inadequate, absorption is impaired, or requirements increase, circulating levels can fall below the reference range.
Certain digestive disorders, including celiac disease, can interfere with the absorption of vitamin B12 and other nutrients. Malnutrition, restricted diets, and some gastrointestinal conditions are also recognized factors that may contribute to low levels. Because the causes vary, a laboratory result is typically interpreted alongside a person's clinical history and other findings.
A blood sample is collected for this test, and results are generally available within one to three business days. Preparation instructions provided by the laboratory should be followed to support accurate measurement. Results outside the reference range do not by themselves establish a diagnosis; they indicate that further evaluation may be appropriate.
