RBC and Bleeding Disorders I Flashcards
anemia
reduction total circulating RBC mass below normal limits
poikilocytic
abnormal shaped RBCs
microcytic normochromic
iron deficiency
macrocytic
megaloblastic
folate B12 deficiency
MCV
mean cell volume
-average volume of a red cell
normal 80-100
to determine size of RBCs
MCH
mean cell hemoglobin
-average content of Hg per red cell
normal 27-33
MCHC
mean cell hemoglobin concentration
average concentration of Hg in given volume packed RBCs
normal 33-37
RDW
red cell distribution width
coefficienct of variation of red cell volume
ration of smallest to largest cell
normal 11.5-14.5
hypoxia of anemia
can lead to fatty changes of liver, myocardium, and kidney
chronic change
normal Hg
13-15
