Iron Studies Comprehensive Panel is a group of blood tests that evaluates the body’s iron levels, storage, transport, and availability for red blood cell production. It typically includes measurements such as serum iron, ferritin, transferrin, and total iron-binding capacity (TIBC), depending on the laboratory. The panel is needed to investigate iron deficiency or overload and help evaluate conditions such as anemia and other disorders affecting iron metabolism.
Total iron-binding capacity (TIBC) estimates the blood's capacity to bind and transport iron. It is often used along with serum iron and transferrin saturation when evaluating iron status.
Transferrin is a protein that transports iron through the bloodstream. Measuring transferrin can provide information about the body's ability to transport iron.
Transferrin saturation represents the percentage of transferrin's iron-binding sites occupied by iron. It is calculated using serum iron and iron-binding measurements.
Low serum iron may occur with iron deficiency, chronic inflammation, certain illnesses, or other conditions. It should be interpreted alongside ferritin, TIBC, transferrin, and clinical findings.
Elevated serum iron may occur with iron overload, certain liver conditions, repeated transfusions, or other causes. Additional tests may be required to determine the reason.
