anemia in general Flashcards
what is anemia and what are the clinical signs
less hemoglobin circulating and functioning (less rbc)
leads to hypoxia
clinical signs: pale mucous membrane, skin
weakness, exercise intolerance
increased respiratory rate, heart rate
how can we determine if the bone marrow is responding?
reticulocyte count high = BM responding, trying to fix anemia
reticulocyte index
what is reticulocyte index
RI=(PCV/0,45) x reticulocyte %
if above 2,5 - regenerative anemia
if under 2,5 - non regenerative anemia
what is the cause of regenerative anemia
RI > 2,5
blood loss: loss of rbc
haemolytic: destruction of RBC
what is the cause of non regenerative anemia
RI<2,5
deficiency anemia (Fe, B12, folic acid)
decreased EPO (normally stimulate BM)
endocrine disorder (hypothyreosis, Addison)
aplastic anemia
several bone marrow producing cells are low/missing
what lab examinations do we do on pale patient
PCV RBC, WBC, PLT-count reticulocyte % morphology of RBC TP Tbr Fe (iron binding capacity): only serum coagulation times: APTT, PTT, ACT
what can PCV show us
ratio of RBC to whole volume
can see color of plasma: icterus or hemolytic
how does TP change in different anemias?
increase in hemolysis
decrease in blood loss
how does TBr change in different anemias
up in hemolysis
