Question 1

Define RBC count. Give units

Answer 1

Obtained using Coulter principle

10^12/L or 10^6/microL

Question 2

Define Hb measurement. Give units.

Answer 2

In vitro measurement of [Hb] released by lysed red cells into whole blood

g/L or g/dL

Question 3

Define hematocrit measurement. Give units.

Answer 3

Measures how much in a given volume of whole blood is occupied by red cells

A percentage

Question 4

Define mean corpuscular volume.

Answer 4

MCV

Mean size of red cells counted

fL

Question 5

Define mean corpuscular hemoglobin

Answer 5

Parameter not used frequently — parallels MCV

Mean quantity of Hb in a single red cell

pico-grams

Question 6

Define mean corpuscular hemoglobin concentration

Answer 6

Average concentration of Hb in red cells

g/dL or g/L

Question 7

Use RBC count, Hb, and Hct, to calculate MCV, MCH, and MCHC

Answer 7

MCV = (Hct/RBC) x 10

MCH = (Hb/RBC) x 10

MCHC = (Hb/Hct) x 100

Answer 8

Count obtained by Coulter principle

Thousands/microL or millions/L
