Transferrin Saturation Formula:
From: | To: |
Transferrin saturation is a medical laboratory value that represents the percentage of iron-binding sites on transferrin that are occupied by iron. It is an important indicator of iron status in the body.
The calculator uses the Transferrin Saturation formula:
Where:
Explanation: The formula calculates the percentage of transferrin that is saturated with iron, providing insight into the body's iron availability and utilization.
Details: Transferrin saturation is crucial for diagnosing iron deficiency anemia, iron overload conditions like hemochromatosis, and monitoring iron therapy effectiveness.
Tips: Enter serum iron and TIBC values in µg/dL. Both values must be positive numbers for accurate calculation.
Q1: What is the normal range for transferrin saturation?
A: Normal values typically range from 20% to 50%, though reference ranges may vary slightly between laboratories.
Q2: What does low transferrin saturation indicate?
A: Low values (<20%) typically indicate iron deficiency anemia or chronic inflammation affecting iron utilization.
Q3: What does high transferrin saturation indicate?
A: High values (>50%) may indicate iron overload conditions such as hemochromatosis or excessive iron supplementation.
Q4: When should transferrin saturation be measured?
A: It should be measured when evaluating suspected iron disorders, monitoring iron therapy, or screening for hereditary hemochromatosis.
Q5: Are there limitations to this calculation?
A: Results can be affected by recent iron intake, inflammation, liver disease, and other factors that influence iron metabolism.
