Typical_morphology_of_Platelets
  • Size : 2-5 µm
  • Normal values : 150-450 x 10(9) /L (depending on the age, sex or physiological changes such as pregnancy)
  • Description / Pathology :

    On MGG staining, the PLT do not contain nucleus.

    They contain purple, violet particles, corresponding to different types of granules.

    • Decreased PLT number (thrombocytopenia) :
      • Central cause: bone marrow impairment;
      • Peripheral cause: platelet destruction by hypersplenism of idiopathic thrombocytopenic purpura (ITP)
    • Increased PLT number (thrombocytosis)
      • Peripheral cause: Inflammation, Chronic Myeloproliferative Syndrome
