A Transferrin test measures the level of transferrin, the main protein that transports iron through your bloodstream. Transferrin levels help evaluate iron status and distinguish between different causes of anemia.
What This Test Measures
Transferrin:
A protein made by the liver that binds iron and transports it throughout the body. Each transferrin molecule can carry two iron atoms. Transferrin levels reflect the body’s iron transport capacity.
Reference Range
Normal: 200-360 mg/dL (varies by laboratory)
Who Should Consider This Test
• Evaluating iron deficiency anemia
• Distinguishing causes of anemia
• Suspected iron overload (hemochromatosis)
• Monitoring iron status
• Chronic disease evaluation
Interpreting Results
High Transferrin:
• Iron deficiency – body makes more transferrin trying to capture limited iron
• Pregnancy
• Estrogen therapy
Low Transferrin:
• Iron overload (hemochromatosis)
• Chronic inflammation or infection
• Liver disease (decreased production)
• Malnutrition
• Nephrotic syndrome (protein loss)
Related Calculations
Transferrin is used to calculate:
• TIBC (Total Iron Binding Capacity) – Estimated from transferrin
• Transferrin Saturation – Percentage of transferrin occupied by iron
