A patient has a serum iron of 10 g/dL and a total iron-binding capacity (TIBC) of 490 g/dL. What is the percent saturation of transferrin?
a. 2%
b. 25%
c. 40%
d. 60%
ANS: A
Percent transferrin saturation is calculated by dividing the serum iron by transferrin and multiplying by 100. Thus in the example here, % saturation = (10/490) ´100 = 2%.
