Iron Saturation Calculator

Input any two values among Serum Iron, Total Iron Binding Capacity (TIBC), and Iron Saturation (%). The calculator determines the missing value using standard hematology formulas.

The Iron Saturation Calculator evaluates the percentage of transferrin saturation in the blood by using Serum Iron and TIBC, or calculates either Serum Iron or TIBC when Iron Saturation is known.

This tool is essential in diagnosing conditions such as iron deficiency anemia or iron overload. By simplifying these calculations, it provides quick and accurate results for medical professionals and individuals monitoring their iron levels.

Formula

Iron Saturation (%)

$\text{Iron Saturation (\%)} = \left( \frac{\text{Serum Iron}}{\text{TIBC}} \right) \times 100$

Serum Iron

$\text{Serum Iron} = \left( \text{Iron Saturation (\%)} \times \text{TIBC} \right) \div 100$

TIBC

$\text{TIBC} = \frac{\text{Serum Iron} \times 100}{\text{Iron Saturation (\%)}}$

Variable	Description	Unit
Serum Iron	Level of iron in the bloodstream	µg/dL or mg/L
TIBC	Total capacity of transferrin to bind iron	µg/dL, mg/dL, or mg/L
Iron Saturation	Percentage of transferrin saturation	%

Step	Value	Explanation
Serum Iron	120 µg/dL	Input value
TIBC	300 µg/dL	Input value
Formula	(Serum Iron ÷ TIBC) × 100	Substitute values
Calculation	(120 ÷ 300) × 100	Perform division and multiplication
Result	40%	Iron Saturation

Example 2: Calculate Serum Iron

Step	Value	Explanation
Iron Saturation	50%	Input value
TIBC	400 µg/dL	Input value
Formula	(Iron Saturation × TIBC) ÷ 100	Substitute values
Calculation	(50 × 400) ÷ 100	Perform multiplication and division
Result	200 µg/dL	Serum Iron
