1

Quantitative

done using some tool to get real value with units, precisely measure exact amount with special tool

2

Qualitative

relative amounts

3

Purpose of Total RBC Count

determine concentration of Red Blood Cells in a sample

4

What is the healthy range of RBC?

4-6million RBC/microliter

5

slide with grid printed on it

hemocytometer

6

How do you get a countable number?

dilute the sample

7

dilution factor

how much the sample is diluted and what you use to multiply with the countable number to achieve total RBC count

8

Determine relative amount of 5 classes of White Blood Cell

Purpose of Differential White Blood Cell Count

9

Why do we use Total RBC Count?

to diagnose blood conditions

10

Too many red blood cells

polycythemia

11

too few red blood cells

anemia

12

why do we count WBC?

to diagnose WBC conditions

13

What is the condition in which a person has too many of one class of cell type?

leukemia

14

what are the 5 types of leukocytes?

neutrophils, basophils, eosinophils, monocytes, lymphocytes

15

predominantly trilobed nucleus

neutrophil

16

healthy range of the amount of neutrophils in a sample?

3000-7000 cells/microliter

17

Big red cytoplasmic granules and bilobed

Eosinophils

18

Usually, how many eosinophils are in a healthy sample?

100-400 cells / microliters

19

Dark cytoplasmic granules, least abundant

Basophils

20

How many basophils are there in a healthy sample?

20-50 cells / microliter

21

what are the two types of leukocytes?

granulocytes and agranulocytes

22

granulocytes

contain granules in cytoplasm of cells

23

agranulocytes

do not contain cytoplasmic granules

24

smallest, rim of cytoplasm around nucleus

lymphocytes

25

how many lymphocytes are usually present in a sample?

1500-3000 cells / microliter

26

puffy U-shaped nucleus and is very large

monocyte

27

How often can you see a monocyte in a healthy sample?

100-700 cells / microliter

28
