Question

what is the major iron storage compund?
a) transferrin saturation
b) tibc
c) serum ferritin
d) serum iron

Explanation:

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

• Option a: Transferrin Saturation measures the amount of iron - bound transferrin, not an iron storage compound.
• Option b: TIBC (Total Iron - Binding Capacity) is related to the capacity of transferrin to bind iron, not an iron storage compound.
• Option c: Serum ferritin is the major iron - storage protein in the body. It stores iron and releases it in a controlled manner when the body needs it.
• Option d: Serum iron refers to the amount of iron in the blood that is bound to transferrin, not a storage compound.

Answer:

c) Serum ferritin
