In a permanent new methylene blue (NMB)-stained smear (equal drops of blood and NMB), the Heinz bodies on the red blood cells are still faint, but far easier to visualize as small round light blue structures (arrows). Again, they are more obvious in ghost RBCs (arrowhead). Note the reticulocyte with small amounts of RNA in a dot-like arrangement, compatible with a punctate reticulocyte (P) (NMB, 100x objective)
