What is the classic triad associated with hereditary spherocytosis?

The classic triad associated with hereditary spherocytosis includes hemolytic anemia, jaundice, and splenomegaly.

In hereditary spherocytosis, the red blood cells are abnormally shaped, resembling spheres rather than the typical biconcave disc shape. These spherocytes are less flexible and more prone to rupture, particularly in the spleen, leading to hemolytic anemia. The breakdown of these red blood cells releases bilirubin, resulting in jaundice. Splenomegaly occurs as the spleen works harder to filter out the defective red blood cells, enlarging due to the increased workload.

Understanding this triad is important for recognizing and diagnosing hereditary spherocytosis effectively. Other options, dealing with conditions unrelated to the classic manifestations of this inherited hemolytic anemia, highlight different disease processes, such as infectious diseases or respiratory issues, which are not characteristic of hereditary spherocytosis.
