Understanding Intrinsic Factor Antibody
Intrinsic factor (IF) is a glycoprotein produced in the stomach lining cells. IF binds to vitamin B12 and enables its absorption in the small intestine. The Intrinsic Factor Antibody test checks for the presence of autoantibodies that target this protein. These antibodies can reduce/block B12 absorption, leading to pernicious anemia, a common cause of vitamin B12 deficiency.
Doctors may advise the Intrinsic Factor Antibody test if there are symptoms such as fatigue, weakness, numbness, or memory issues, or if ther...
