Causes of anemia may be classified by pathophysiology, such as comparing acquired versus inherited causes, or mechanisms of anemia such as decreased RBC production versus increased destruction. In clinical practice, more often the evaluation of maternal anemia starts with the mean corpuscular volume (MCV), based on which anemias are defined as microcytic (less than 80 fL), normocytic (80–100 fL) or macrocytic (greater than 100 fL) (Figure 11.1).
