MCHC

10

increase in RDW suggests what

what conditions

increase in different types of cell sizes

factor deficiency, homozygous globinpathy

what are polychromatophile RBCs

reticulocytes
immature RBCs

14

what is rouleaux

rbcs partially adhering to each other like stack of coins

15

what is anemia defined as

decrease in hemoglobin concentration

(may result from loss of RBCs which contain hb)

what are the steps to determine if patient is anemic

ask question - are they anemia
morphology classification
pathogenesis

20

factor deficiency results from what

lack of raw materials necessary for hematopoesis

si increases
tibc decreases

30

macrocytosis results from what

b12 or folic acid deficit
