• Causes
  • The investigation of leukocytosis begins with an understanding of its two basic causes: (1) the appropriate response of normal bone marrow to external stimuli and (2) the effect of a primary bone marrow disorder. (aafp.org)

  • Hematologic causes of leukocytosis include acute or chronic leukemias and myeloproliferative diseases. (cancertherapyadvisor.com)
  • The mechanism that causes leukocytosis can be of several forms: an increased release of leukocytes from bone marrow storage pools, decreased margination of leukocytes onto vessel walls, decreased extravasation of leukocytes from the vessels into tissues, or an increase in number of precursor cells in the marrow.

  • Bone Marrow
  • Occasionally, leukocytosis is the sign of a primary bone marrow abnormality in white blood cell production, maturation or death (apoptosis) related to a leukemia or myeloproliferative disorder. (aafp.org)
  • diagnosis
  • For lung diseases such as pneumonia and tuberculosis, WBC count is very important for the diagnosis of the disease, as leukocytosis is usually present. (wikipedia.org)
  • chronic
  • Also important in understanding normal ranges is that slightly more than 2% of the normal population, based on the normal distribution in which the range was established, will have a chronic leukocytosis that is "normal" for them. (cancertherapyadvisor.com)
  • laboratory
  • Leukocytosis, defined as a white blood cell count greater than 11,000 per mm 3 (11 ×10 9 per L), 1 is frequently found in the course of routine laboratory testing. (aafp.org)

  • Leukocytosis is an increase in the number of white blood cells found in the blood. (providence.org)
  • cause
  • The mechanism in which hyperleukocytosis / leukostasis manifests and disrupts homeostasis is greatly associated with leukemia's but there are multiple other factors that may cause leukocytosis. (wikipedia.org)
  • common
  • The 97.5 percentile (right limits in intervals in image, showing 95% prediction intervals) is a common limit for defining leukocytosis. (wikipedia.org)
