Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears , urine samples, and bone marrow aspirates , which are examined under a light microscope .

This stain develops varying colors for all cell structures (“Romanowsky-Giemsa effect) and thus was used in staining neutrophil polymorphs and cell nuclei. Common variants include Wright's stain, Jenner's stain, May-Grunwald stain, Leishman stain and Giemsa stain. All are used to examine blood or bone marrow samples.
Pappenheimer bodies are visible with a Wright and/or Giemsa stain. Confirmation of non-heme iron in the granules is made with a Perls' Prussian blue stain, and this atypical red blood cell is then known as a siderocyte. [5] Only the finding of ring (or ringed) sideroblasts characterizes Sideroblastic anemia.
Routine analysis of blood in medical laboratories is usually performed on blood films stained with Romanowsky stains such as Wright's stain, Giemsa stain, or Diff-Quik. Wright-Giemsa combination stain is also a popular choice. These stains allow for the detection of white blood cell, red blood cell, and platelet abnormalities.
