Question

what is the most sensitive test for iron deficiency anemia? a) serum ferritin b) transferrin c) serum iron d) tibc

Explanation:

Serum ferritin reflects the body's iron - stores. In iron deficiency anemia, serum ferritin levels decrease early as the body's iron stores are depleted. Transferrin, serum iron, and TIBC (Total Iron - Binding Capacity) can be affected by other factors and are not as sensitive as serum ferritin for detecting early iron deficiency.

Answer:

a) Serum Ferritin
