what is the major iron storage compund?\na) transferrin saturation\nb) tibc\nc) serum ferritin\nd) serum iron

Brief Explanations:

To determine the major iron storage compound, we analyze each option:

• Option a: Transferrin Saturation measures transferrin’s iron - binding capacity, not iron storage.
• Option b: TIBC (Total Iron - Binding Capacity) relates to transferrin’s ability to bind iron, not storage.
• Option c: Serum ferritin is the major iron - storage protein in the body, storing iron.
• Option d: Serum iron refers to iron in the blood, not stored iron.

Answer:

c) Serum ferritin
