![Eosinophil Eosinophil](/fileadmin/media/f100/images/CellImages/Eosinophil.png)
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%.

The bone marrow cytology (May-Grünwald-Giemsa stain) of a patient with ET shows a clear increase in exceptionally large megakaryocytes.

Extreme thrombocytosis (3,400,000/μL) in chronic myelogenous leukaemia (CML, bcr-abl+); on the right a basophilic granulocyte.

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'.
