WHAT IS VITAMIN B12 (CYANOCOBALAMIN, CBL, EXTRINSIC FACTOR) TEST?

Vitamin B12 (cyanocobalamin) is a water-soluble vitamin obtained from dietary animal sources that are necessary for proper deoxyribonucleic acid (DNA) synthesis. It can be absorbed from the gastrointestinal tract only when intrinsic factor glycoprotein secreted from the stomach’s parietal cells is present. Although the body stores up to a 12-month supply of this vitamin in the liver, kidneys, and heart, rapid growth states or conditions causing rapid turnover of cells increases the body’s need for vitamin B12. Symptoms of vitamin B12 deficiency include anaemia; a smooth, red, painful tongue (glossitis); and neurologic abnormalities of extremity paresthesias.
