WBC CBC Flashcards
complex process where blood cells form, proliferate, differentiate, and mature
hematopoiesis
where does hematopoiesis occur in adults?
bone marrow
originator stem cell of all blood
multi potential stem cell
lymphoid stem cell line
lymphocyte (B and T cells)
myeloid cell line
basophils, eosinophils, neutrophils, monocytes, platelets
total number of leukocytes
WBC
percentages of different types of blood cells
differential
normal value of WBC
4500-10500/mm3
bacterial infection = ____ WBC
HIGH
leukocytosis
viral infection = ___ WBC
LOW
leukopenia
leukocytosis value
> 10,000/mm3
leukopenia value
< 4000/mm 3
leukocytosis
elevated WBC
increase in ONE type of cell (infection, leukemia, drugs -steroids)
leukopenia
low WBC
viral infection, bone marrow depression, hyperspelnism
leukomoid reaction
marked increase in WBC (50,000 - 100,000 /mm3)
due to infection but increase is only temporary
panic values for total WBC
<500 or >30,000
“polys” listed in differential
bands, segmented neutrophils, eosinophils and basophils
aka granulocytes
what leukocytes are most abundant in a diff
segs/polys (neutrophils) 50-70%
followed by lymphocytes (20-30%)
