New methylene blue (also NMB) is an organic staining agent used in diagnostic cytopathology and histopathology, typically for staining immature red blood cells. It is closely related to methylene blue, an older stain already in wide use.

New methylene blue is toxic. Skin contact or inhalation should be avoided.
