How does lymphocytosis and thrombocytosis take place?
Answers
Thrombocytosis is a disorder in which your body produces too many platelets (thrombocytes), which play an important role in blood clotting. The disorder is called reactive thrombocytosis or secondary thrombocythemia when it's caused by an underlying condition, such as an infection.
Thrombocytosis (throm-boe-sie-TOE-sis) may also, less commonly, be caused by a blood and bone marrow disease. When caused by a bone marrow disorder, thrombocytosis is called autonomous, primary or essential thrombocytosis, or essential thrombocythemia Your doctor may detect thrombocytosis in routine blood test results that show a high platelet level. If your blood test indicates thrombocytosis, it's important to determine whether it's reactive thrombocytosis or if you have essential thrombocythemia, which is more likely to cause blood clots.Leukocytosis, defined as a white blood cell count greater than 11,000 per mm3 (11 ×109 per L),1 is frequently found in the course of routine laboratory testing. An elevated white blood cell count typically reflects the normal response of bone marrow to an infectious or inflammatory process. 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. Often, the family physician can identify the cause of an elevated white blood cell count based on the findings of the history and physical examination coupled with basic data from the complete blood count.
