Exam 1: CBC

Question 1

What is included in the minimum database?

Answer 1

CBC
Serum biochemical panel
urine analysis

Question 2

Parameters of red cell mass

Answer 2

RBC concentration/count
PCV/Hct
Hgb concentration

Question 3

How is Hct calculated?

Answer 3

MCV x RBC conc

Question 4

If RBC count, Hgb count, or PCV was wierd, what would you look at next?

Answer 4

MCV (if increased, PCV increased)
MCHC (if increased, PCV increased)
Is sample lysed? - look at MCHC, Hgb vs. PCV

Question 5

3 terms used to describe MCV (mean cell volume)

Answer 5

Macrocytic
Normocytic
Microcytic

Question 6

How do you calculate MCHC (mean cell hgb conc)

Answer 6

Hgb/Hct

Question 7

If RDW (red cell distribution width) is increased, what does that mean?

Answer 7

% increased variability in RBC sizes in sample

aka anisocytosis present

Question 8

Anisocytosis

Answer 8

morphological variation in size
RDW - tells you there’s variation
MCV - tells you larger or smaller cells
