TABLE 7.3 Staining Characteristics of Erythrocytes and Inclusions

Stain

Inclusion Feulgen a Supravital b Wright

Basophilic stippling Negative Positive Positive

Cabot rings Negative Negative Positive

Howell-Jolly bodies Positive Positive Positive

Polychromatophilia Negative Negative Positive

Reticulocytes Negative Positive Negative

Pappenheimer bodies Negative Positive Positive

Heinz bodies c Negative Positive Negative or positive

a Feulgen stain demonstrates the presence of DNA.

b Supravital stains (e.g., new methylene blue or brilliant cresyl blue) demonstrate the presence of RNA.

c Can be demonstrated with crystal violet stain.
