Iron Overload

• Conditions such as hemochromatosis result in elevated ferritin levels.

Inflammation/Infection

• Because ferritin is an acute-phase protein, levels may rise in infections, autoimmune diseases, or other inflammatory conditions.

Liver Disease & Malignancy

• Chronic liver disease or certain cancers can cause ferritin to elevate either due to iron metabolism dysregulation or as part of a systemic inflammatory response.

‍

Iron Deficiency Anemia

• Low ferritin is the most sensitive marker for depleted iron stores, leading to anemia.

Nutritional Deficiencies/Malabsorption

• Chronic malnutrition or gastrointestinal disorders affecting absorption can reduce ferritin levels.

‍

Children

• Normal ferritin values differ based on growth needs, and iron deficiency is common during rapid growth periods.

Reproductive-Age Women

• Menstruation can lower iron stores.

Elderly

• Chronic low-level inflammation might mask iron deficiency by elevating ferritin levels despite depleted iron stores.

Mineral and Iron Metabolism

• Blood Phosphorus:
  An essential mineral important for bone health and cellular energy, contributing to overall metabolic balance.
  
  
• Copper:
  A trace mineral vital for enzymatic activities, particularly for oxidizing iron, which is necessary for its transport.
  
  
• Ferritin:
  The body’s primary storage protein for iron; it reflects the level of stored iron and helps assess iron sufficiency or overload.
  
  
• Serum Iron:
  Indicates the amount of circulating, available iron for metabolic processes.
  
  
• Total Iron Binding Capacity (TIBC):
  Measures the blood’s capacity to bind iron via transferrin; it is inversely related to iron stores.
  
  
• serum ceruloplasmin:
  A copper-binding protein produced by the liver that enables iron oxidation and transport, linking copper and iron metabolism.
  
  

These markers interconnect to provide a comprehensive assessment of iron and copper homeostasis. Ferritin, Serum Iron, and Total Iron Binding Capacity (TIBC) directly gauge iron status, while Copper and serum ceruloplasmin work together in the regulation and oxidation of iron. Blood Phosphorus, though not directly involved in iron-copper metabolism, rounds out the picture by offering insights into the overall mineral and metabolic state.
