1. What is TSAT?

TSAT (Transferrin Saturation) is a medical laboratory value that represents the percentage of transferrin that is saturated with iron. It is calculated as the ratio of serum iron to total iron-binding capacity (TIBC) multiplied by 100.

2. How Does the Calculator Work?

The calculator uses the TSAT formula:

Where:

• Serum Iron — Measured in μg/dL
• TIBC — Total Iron-Binding Capacity measured in μg/dL

Explanation: The formula calculates the percentage of transferrin iron-binding sites that are occupied by iron.

3. Importance of TSAT Calculation

Details: TSAT is an important marker for assessing iron status in the body. It helps diagnose iron deficiency anemia, iron overload conditions, and monitor iron therapy effectiveness.

4. Using the Calculator

Tips: Enter serum iron and TIBC values in μg/dL. Both values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the normal range for TSAT?
A: Normal TSAT values typically range from 20% to 50% in adults.

Q2: What does a low TSAT indicate?
A: Low TSAT (usually below 20%) typically indicates iron deficiency.

Q3: What does a high TSAT indicate?
A: High TSAT (usually above 50%) may indicate iron overload conditions such as hemochromatosis.

Q4: When should TSAT be measured?
A: TSAT should be measured when evaluating iron status, monitoring iron therapy, or investigating suspected iron disorders.

Q5: Are there limitations to TSAT measurement?
A: TSAT can be affected by recent iron intake, inflammation, and other factors. It should be interpreted in clinical context along with other iron studies.
