Serum or plasma ferritin concentration as an index of iron ...

Background: Reference standard indices of iron deficiency and iron overload are generally invasive, expensive, and can be unpleasant or occasionally risky. Ferritin is an iron storage protein and its concentration in the plasma or serum reflects iron stores; low ferritin indicates iron deficiency, while elevated ferritin reflects risk of iron overload.

Iron deficiency anemia

The total iron binding capacity (TIBC) is a measure of the plasma’s ability to carry iron and represents the maximum concentration of iron that can be bound by plasma transferrin. This test is often performed as part of an iron panel, but is of limited clinical value in small animals, as it does not assess serum or tissue iron levels and does ...
