Blood count and blood film changes in infection and inflammation Flashcards
what factors can affect normal blood count ranges
obesity, smoking, age, gender, ethnicity, excercise, geographical location
what do you normally see in a blood film
neutrophils, eosiniphills, basophills, monocytes, erythrocytes, lymphocytes, platelets(thrombocytes), band neutrophils(not as devloped)
what do lymphocytes originate from
pluripotent stem cell then lymphoid stem cell then lymphocyte
how do all blood cells in blood arise apart from lymphocytes
pluripotent stem cell then from myeloid stem cell which then further differentiates accordingly
what is function of neutrophils
phagocytosis fast acting
what is role of eosinophils
attacks parasites allergic reaction
what is basophil role
histamin and heparin relase
what is function of monoctytes
phagocytosis slow response
what would you expect to see in someone with epstein barr virus
sore throat, fatigues, enlarged cervical lymph nodes, anaemia and thrombocytopenia, lymphocytosis
what can cause lymphocytosis
viral infection, bacterial infection, tissue infarction, stress related, cigarette smoking, if none of the above then haematological malignancy lymphomas etc
what does lymphocytosis mean
Lymphocytosis (lim-foe-sie-TOE-sis), or a high lymphocyte count, is an increase in white blood cells called lymphocytes.
what causes red cell agglutination
infection(HIV EBV, mycoplasma), Cll, waldenstroms, macroglobulinemia and autoimmune conditions SLE RA
what does neutropenia mean
low level of neutrophils
what does neutrophilia mean
high neutrophil count
what would you expect to see in someone with bacterial sepsis
neutrophilia, toxic granulation and left shift, anaemia, leukoerythroblastic, thrombocytopenia or thrombocytosis, haemolyisis
