What Is Intrinsic Factor?
Intrinsic Factor (IF) is a protein produced by the stomach. It is crucial for the absorption of vitamin B12 from food in the intestines. Without sufficient IF, the body cannot effectively absorb vitamin B12, which is essential for the production of red blood cells and the function of the nervous system.
Why Should You Have Intrinsic Factor Tested?
A test for Intrinsic Factor may be recommended if there are symptoms of vitamin B12 deficiency, such as fatigue, weakness, memory loss, or neurological symptoms. It is also useful for diagnosing certain conditions, such as pernicious anemia, an autoimmune disease where the body produces insufficient IF.
What Does It Indicate?
The amount of Intrinsic Factor in the body can help determine the cause of vitamin B12 deficiency. It indicates whether the deficiency is caused by a problem with IF production or by other factors.
What Does a High Intrinsic Factor Level Mean?
A high level of Intrinsic Factor is usually not problematic and does not directly indicate a specific condition. The focus is mainly on detecting low levels of IF.
What Does a Low Intrinsic Factor Level Mean?
A low level of Intrinsic Factor may indicate pernicious anemia or other conditions affecting vitamin B12 absorption. This can lead to a range of health issues, including anemia and neurological damage.
