Intrinsic Factor Blocking Antibody

The Intrinsic Factor Blocking Antibody test is a vital diagnostic tool used to assess pernicious anemia, a condition where the body's ability to absorb vitamin B12 is impaired due to the lack of intrinsic factor, a protein needed for vitamin B12 absorption.

Intrinsic factor blocking antibodies are autoantibodies that target and inhibit intrinsic factor, leading to vitamin B12 deficiency and subsequent symptoms such as fatigue, weakness, and neurological problems.
