Iron Studies (Fe / TIBC / Ferritin)

Iron Studies is a group of blood tests that evaluates the amount of iron in your body and how effectively it is transported and stored. The panel typically includes:

• Serum Iron (Fe): Measures the amount of iron circulating in the blood.
• Total Iron Binding Capacity (TIBC): Measures the blood's capacity to bind and transport iron through the protein transferrin.
• Serum Ferritin: Measures the body's stored iron and is the most reliable indicator of iron reserves.

Some laboratories may also include Transferrin Saturation (%TSAT) and Unsaturated Iron Binding Capacity (UIBC).

Iron studies help diagnose iron deficiency, iron overload, anemia, chronic diseases, and disorders affecting iron metabolism.

Doctors may recommend Iron Studies to:

• Diagnose iron deficiency anemia
• Determine the cause of anemia
• Detect iron overload disorders such as hemochromatosis
• Evaluate chronic fatigue and weakness
• Assess nutritional deficiencies
• Monitor iron supplementation therapy
• Investigate unexplained low or high hemoglobin levels
• Evaluate chronic inflammatory diseases
• Assess iron status during pregnancy
• Monitor patients with chronic kidney disease or liver disease

Fasting for 8–12 hours is often recommended, especially for Serum Iron, as iron levels can fluctuate after meals.

Water is allowed during the fasting period.

Blood samples are preferably collected in the morning.

Inform your doctor about iron supplements, multivitamins, or recent blood transfusions.

Your healthcare provider may advise temporarily stopping iron supplements before testing if clinically appropriate.
