Answer

The reticulocyte percentage documents the briskness of the marrow response. If the reticulocyte count is normal, splenic sequestration is the probable cause. If the reticulocyte count is low, an aplastic crisis is the probable cause. If the reticulocyte count is high, hyperhemolytic crisis is the probable cause.
