Which stain is used to visualize Heinz bodies?

Visualizing Heinz bodies relies on a supravital stain that highlights delicate, denatured hemoglobin precipitates inside red cells. Methylene blue is a classic supravital stain that stains these precipitates, making Heinz bodies appear as small blue inclusions within the cell. Standard fixed stains like Wright or Giemsa don’t reliably reveal Heinz bodies because the inclusions are fragile and can be lost or faint after fixation. Prussian blue, on the other hand, stains ferric iron in hemosiderin, not the protein precipitates of Heinz bodies, so it won’t show them. Hence, methylene blue is the appropriate stain to visualize Heinz bodies.
