Size: 12-17 µm
Nucleus: usually bilobed with visible filament
Cytoplasm: weekly basophilic containing coarse reddish-orange granulation packing the cytoplasm
Function: Phagocytosis, chemotaxis, mortification of parasites, inhibition of mastcell degranulation, eutralization of histamine

Pronounced erythrocytosis (polyglobulia) can often already be recognised after sedimentation of the red blood cells. Left tube: haematocrit 82%, right tube: haematocrit 39%.

In the impedance channel of a haematology analyser a falsely elevated platelet concentration of 850,000/μL was measured. This was caused by precipitated cryoglobulin in cryoglobulinaemia. The flocculated cryoglobulin is visible in the phase contrast microscope in between the red blood cell 'rouleaux'.
