: Could somebody give me a definition for the so-called phenomena:
: leukocytosis and leukopenia? Especially, is it correct to use these
: terms for respectively an increase or a decrease in total circulating
: leukocyte numbers? Do these phenomena necessary imply some kind of
: involvement of hemopoietic organs?
No, leukocytosis and leukopeia don't necessarily imply problems
with hematopoiesis. Leukocytosis is an increase in leukocytes, which MAY
be the actual disease state(primary leukocytosis), or it may be a
reactive process, in which the immune system is responding to another
problem(secondary leukocytosis). The same goes for leukopenia...primary
leukopenia is due to abnormal white cell development, while secondary is
a result of another problem.
If I can provide any further information, feel free to ask.
