laboratory tests Flashcards
what is leukocytosis
WBCs greater than 10,000 microliter uL
what is the normal value of white blood cells
4500-10,000 uL
what is left shift
increase in neutrophils
what is elevated erythrocyte sedimentation
rate ESR pver 200mm/hr
what does an increase in erythrocyte sedimentation indicate
active inflammatory process or infection
presence of fluid/area
what does it mean that white blood cells can be ordered differential
different values of all WBCs
what does circulating neutrophils consist of
band neutrophils and segmented neutrophils
(latter between mature type)
what are circulating neutrophils distinguishable by
segmented appearance (segs)
what are immature neutrophils called
bands (non segmented)
what are elevated concentration of band neutrophils in the
blood is always the result of
infection or inflammation
what is erythrocyte sedimentation rate
rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour.
It is a common hematology test, and is a non-specific measure of inflammation
