hematogone

Answer 1

lymphocyte precursor

Question 2

components of a CBC

Answer 2

WBC
RBC
platelet
hemoglobin
hematocrit

RBC indices: MCW, mean cell hemoglobin, mean cell hemoglobin concentration, red cell distribution width

Question 3

differential count

Answer 3

leukocyte composition

Question 4

anisocytosis

Answer 4

variation in cell size (disease state-can see anisocytosis of RBCs)

Question 5

size of erythrocyte

Answer 5

7 micrometers

Question 6

secondary granules are also called

Answer 6

specific granules

Question 7

size of neutrophils

Answer 7

10 micrometers

Question 8

describe nucleus of eosinophils

Answer 8

bilobed

Question 9

what do granules of eosinophils contain

Answer 9

major basic proteins (to combat parasites)

Question 10

role of eosinophils

Answer 10

parasitic infec

allergic rxns

Question 11

lymphocyte size

Answer 11

5-15 micrometers (varies because there’s different types-T, B, NK cells-and because of the maturity of a given cell)

Question 12

is it abnormal for reticulocytes to be in peripheral blood?

Answer 12

no b/c they complete their maturation during the first 24-48 hrs in the circulation

Question 13

bone marrow cellularity is estimated how

Answer 13

relative percentage of hematopoietic cells compared to fat

normal cellularity = 100-age

Question 14

nuclei of maturing erythroids vs granulocytic precursors

Answer 14

maturing erythroids have “ink dot” perfect round nuclei

granulocyteic precursors show variable degrees of segmentation

Question 15

absolute count in WBC differential is calculated how

Answer 15

percent cell type x WBC count
