INTRINSIC FACTOR ANTIBODY(O.S.)

Overview

The Intrinsic Factor Antibody test detects antibodies against intrinsic factor, a protein essential for vitamin B12 absorption in the intestines. This test is primarily used to diagnose pernicious anemia, an autoimmune disorder that impairs B12 absorption, leading to deficiencies that can cause anemia and neurological issues. Elevated levels may indicate an autoimmune response affecting B12 absorption.
