Mentzer index

From Wikipedia, the free encyclopedia

The Mentzer index is used to differentiate iron deficiency anemia from beta thalassemia. It is calculated from the results of a complete blood count. If the quotient of the mean corpuscular volume divided by the red blood cell count is less than 13, thalassemia is more likely. If the result is greater than 14, then iron-deficiency anemia is more likely.
