Differential Diagnosis for Decrease Iron, Increase TIBC, Decrease Percent Iron Saturation, Increase Unbound Iron Binding Capacity

  • Single Most Likely Diagnosis

    • Iron Deficiency Anemia: This condition is characterized by decreased iron levels, increased Total Iron Binding Capacity (TIBC), decreased percent iron saturation, and increased unbound iron binding capacity. The body's demand for iron exceeds its supply, often due to inadequate dietary intake, increased requirement (e.g., pregnancy), or chronic blood loss.

  • Other Likely Diagnoses

    • Chronic Disease: Certain chronic diseases can lead to a decrease in iron levels and an increase in TIBC due to the body's inflammatory response, which can affect iron metabolism. Examples include chronic infections, autoimmune diseases, and cancer.
    • Pregnancy: Pregnancy increases the demand for iron due to the increased blood volume and the needs of the fetus, leading to decreased iron levels and increased TIBC if the demand is not met by dietary intake or supplements.
    • Vegetarian or Vegan Diet: A diet lacking in animal products can lead to iron deficiency due to the lower bioavailability of iron from plant sources, resulting in decreased iron levels and increased TIBC.

  • Do Not Miss Diagnoses

    • Celiac Disease: This autoimmune disorder can lead to malabsorption of nutrients, including iron, resulting in iron deficiency anemia. It's crucial to diagnose and treat celiac disease to prevent long-term complications.
    • Internal Bleeding: Chronic internal bleeding, such as from ulcers or cancer, can cause iron deficiency anemia. Identifying and treating the source of bleeding is critical to prevent severe outcomes.
    • Malignancy: Certain cancers can cause iron deficiency anemia either through bleeding, malabsorption, or the effects of the cancer on the body's metabolism.

  • Rare Diagnoses

    • Hereditary Atransferrinemia: A rare genetic disorder characterized by the absence or very low levels of transferrin, the protein responsible for binding and transporting iron in the blood. This leads to decreased iron levels and increased TIBC.
    • Aceruloplasminemia: Another rare genetic disorder that affects the metabolism of iron and copper, leading to iron accumulation in tissues but decreased iron levels in the blood, potentially presenting with increased TIBC.
