• Causes
  • Leukocytosis is a condition that causes you to have too many white blood cells (WBC). (drugs.com)
  • It is important for clinicians to be able to distinguish malignant from non-malignant etiologies, and to differentiate between the most common nonmalignant causes of leukocytosis. (aafp.org)
  • 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)
  • 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. (wikipedia.org)
  • Hematologic causes of leukocytosis include acute or chronic leukemias and myeloproliferative diseases. (cancertherapyadvisor.com)
  • typically
  • Although CML typically elevates the WBC, polycythemia vera elevates the red blood cell count, and essential thrombocythemia raises the platelet count, all four myeloproliferative diseases overlap and each often results in a leukocytosis (less commonly with essential thrombocythemia).

  • 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)
  • myeloproliferative
  • 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)
  • exercise
  • These results are consistent with the suggestion that the immediate and delayed leucocytosis induced by exercise are mediated respectively by catecholamine and by cortisol. (springer.com)
  • McCarthy D, Dale MM (1988) The leucocytosis of exercise: a review and model. (springer.com)
  • blood
  • Leukocytosis, often defined as an elevated white blood cell (WBC) count greater than 11,000 per mm 3 (11.0 × 10 9 per L) in nonpregnant adults, is a relatively common finding with a wide differential. (aafp.org)
  • 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)

  • Medical researchers define Leukocytosis as a condition characterized by an unusual rise in white blood cell quantity in the bloodstream. (primehealthchannel.com)
  • Leukocytosis is an increase in the number of white blood cells found in the blood. (providence.org)
  • cause
  • They may also help to find the cause of your leukocytosis. (drugs.com)
  • Without treatment, your leukocytosis may get severe and cause bleeding or damage to your lungs or kidneys. (drugs.com)
  • 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)
