WEEK 2 Scheme Flashcards
what is a leukopenia
a reduced white cell count
what is the normal WBC count
4-10 wc/ml (most are neutrophils)
what is it called when the wbc count is higher than 10
leukocytosis
what is it called when the wbc count is less than 10
leukopenia
what are the 2 main categories of leukopenia
neutropenia = decreased # neutrophils Lymphopenia = decreased # of lymphocytes
when circulating neutrophils are less than 1500 aka less than 1.5 neutrophils / mL what does that mean
neutropenia
What are the common causes of neutropenia?
bacterial or fungal infections
What are common caues of lymphopenia
viral infections
what does lymphopenia mean
circulating lymphocytes are less than 1500
what does leukocytosis mean
circulating neutrophils are higher than 7000. The increased number of neutrophils is due to infection of inflammation
what does leukemoid reaction mean
the degree of wbc is so high that it starts to look like a leukemia, but it is not an actual leukemia
clonal elevations in wbc’s are called
leukemias
acute leukemias involve what kind of cells
blasts (immature cells) they affect children and the elderly and have short and drastic life course
what kind of cells are involved in chronic forms of leukemia
proliferation of mature cells, affect people in mid life and have a longer less devastating course
what can increased basophils on blood smear indicate
chronic myeloid leukemia
