How to Use This Calculator
- Enter your serum iron level in μmol/L. This measures the amount of iron currently circulating in your blood.
- Enter your total iron binding capacity (TIBC) in μmol/L. This represents the maximum capacity of transferrin to bind iron.
- Select your gender. Reference ranges differ between males and females.
- (Optional) Enter your age if you want more personalized results.
- Click the "Calculate" button to determine your transferrin saturation percentage.
Understanding Transferrin Saturation
Transferrin saturation is a measure of how "saturated" transferrin (a protein that transports iron in the blood) is with iron. It helps assess iron status in the body:
- Normal Range: Typically below 16% for males and below 20% for females
- Elevated Range: 16-20% for males, 20-30% for females
- Highly Elevated Range: Above 20% for males, above 30% for females
Important Notes:
- This calculator provides an estimate of transferrin saturation and should not replace professional medical advice.
- High transferrin saturation may indicate iron overload conditions like hemochromatosis.
- Low transferrin saturation may suggest iron deficiency.
- Always consult with a healthcare provider for proper interpretation of lab results.
