CBC Flashcards
WBW abnormalities
infection, inflammation, neoplasm, malignancy, drug reactions
Hbg/Hct abn
anemia, polycythemia
Plt abn
bleeding disorders, hypercoagulable states
RR WBC
5000-10000 adult
6200-17000 kid <2
9000-30000 newborn
components of WBC
WBC count (total leukocytes0 Differential (% each type of leukocyte)
differential WBC
Neutrophil 55-70% Lymphocytes 20-40% Monocytes 2-8% Eosinophils 1-4% Basophils 0.5-1%
NLMEB
Granulocytes (of WBC)
have granules in cytoplasm and multilobed nuclei aka PMN (polymorphonuclear leukocytes
*include NEUTROPHILS, EOSINOPHILS, BASOPHILS
phil = granulocyte
Neutrophils are what
granulocyte, most common PMN (immature neutrophil is band)
NEUTROphils PHAGOCYTIZE BACTERIA
Eosinophils are what
granulocytes
involved in allergic rxn (and parasitic?)
Basophils are what
aka MAST cells
involved in allergic rxn (contain histamine for allergic rxn.. hive or wheal)
What are the nongranulocyte WBC
Lymphocytes (T and B cells) - fight acute viral and chronic bacterial infections
Monocytes: phagocytic cells capable of fighting bacteria like neutrophils do
Monocytes and what are similar bc why
monocytes ~ neutrophils bc both fight bacteria/phagocytic
what do lymphocytes do
agranulocyte WBC composed of T and B cells; fights acute viral and chronic bacterial infection
Leukocytosis is defined as what and causes are
leukocytosis >10000
*bacterial infection, inflammation, malignancy/neoplasm, leukemoid response, steroid
BSLIM (bacteria, Steroid, Leukomoid resp, inflammation, malignancy)
Leukopenia is what and caused by what
<50000 cause: viral infection, overwhelming bacterial infection, bone marrow failure, drug toxicity, autoimmune dz
