Erythrocyte indices

Also commonly called red blood cell indices or RBC indices, the erythrocyte indices are a set of clinically useful parameters calculated from measurements of erythrocytes. These are commonly reported as part of a complete blood count.

Mean corpuscular volume
Usually called MCV, this is the average volume enclosed by a red cell, calculated as: MCV = 10 x (Hematocrit / Red Blood Cell Count)

Mentzer index
Mentzer Index = MCV / RBC Count
 * Ratio <13: Thalassemia
 * Ratio >13: Iron deficiency anemia, Hemoglobinopathy
