Intro to Hematopathology- Krafts

Question 1

Complete Blood Count:

1. RBC
2. Hemoglobin
3. Hematocrit

Answer 1

1. RBC - count
2. Hemoglobin - [ ] in blood, nothing to do with # of cells
3. Hematocrit - index taht tells you the amount of RBCs as a % of total blood volume (norm 40%)
   - -calculated: # RBC * size

Question 2

MCV=

Answer 2

Mean corpuscular volume
-AVERAGE SIZE

Helps determine different anemias

Question 3

RDW=

Answer 3

Red cell Distribution

Are they all the same size?

Question 4

MCH=

Answer 4

WEIGHT of Hgb in red cell

Question 5

MCHC=

Answer 5

CONCENTRATION of Hgb in red cell

Question 6

CBC gives you:

Answer 6

RBC, Hgb, Hematocrit
MCV
RDW
MCH
MCHC
WBC
WBC differential 
Platelet count
MPV

Question 7

MPV=

Answer 7

-not used much

Question 8

10 things to look at on a blood smear

Answer 8

1. RBC #
2. RBC size (microcyte vs macrocyte)
3. RBC shape
4. RBC chromasia= how much Hgb is in each cell
5. Reticulocytes
6. Weird stuff
7. WBC #
8. WBC differential
9. Platelet count
10. Platelet morphology

Question 9

Normal zone of pallor?

Hypochromic RBC?

Answer 9

1/3 of cell

big zone of central pallor=decreased Hgb
