Segmented Neutrophil

  • 10-15 microns
  • Nucleos with coarse, clumped chromatin structure with 3-5 segments
  • Plentiful pale pink to colorless cytoplasm
  • Moderate to plentiful very fine violet granules
 

Band Neutrophil

  • 10-15 microns
  • Band shaped nucleus with coarse, clumped chromatin structure. The narrowest part is at least 1/3 of the widest. No nucleoles
  • Pale pink to colorless cytoplasm
  • Plentiful very fine violet granules
 

Eosinophil

  • 10-15 microns
  • Nucleos with coarse, clumped chromatin structure with 2-3 segments
  • Cytoplasm nearly invisible due to the granulation, pale, pink to colorless
  • Plentiful large, round brick-red granules
 

Basophil

  • 10-15 microns
  • Nucleus with diffuse, clumped chromatin structure with 3-4 poorly difined segments
  • Plentiful pale pink to colorless cytoplasm
  • Moderate to plentiful, unevenly sized,round,bluish-black granules
 

Small Lymphocyte

  • 7-8 microns
  • Round or kidney-shaped nucleus, diffusely lumpy to compact chromatin structure
  • Narrow cytoplasm edge, light or dark blue
  • Possible isolated bright violet granules
 

Large Lymphocyte

  • 9-15 microns
  • Oval/bulging nucleus, somewhat looser chromatin structure than the small lymphocyte. No nucleoles
  • Plentiful colorless to light blue cytoplasm
  • Possible isolated bright violet granules
 

Monocyte

  • 12-24 microns
  • Kidney-shaped, bulging or segmented nucleus, very loose web structure
  • Plentiful, dirty grey cytoplasm
  • Possible powder-fine, violet granules
  • Vacuoles often appear in the cytoplasm
 

Erythrocyte

  • 6-8 microns
  • No nucleus
  • Faintly reddish cytoplasm,clearing towards the center
  • No granules
 
 

Thrombocytes

  • 1-15 micron
  • Cytoplasm fragment of the megakaryocyt
  • Light blue to colorless cytoplas
  • Scattered red granules
