What does a total WBC count determine?

The total number of WBCs per unit volume of blood

2

What does a total RBC count determine?

The total number of RBCs per unit volume of blood

3

What is leukocytosis?

An abnormally high WBC count

4

What 5 conditions may leukocytosis indicate?

1. Bacterial infection

2. Viral infection

3. Metabolic disease

4. Hemorrhage

5. Poisoning by drugs/chemicals

5

What is leukopenia?

A decrease in the white cell number below 4000 per cubic millimeter of blood

6

What 5 conditions may leukopenia indicate?

1. Infectious hepatitis

2. Infectious cirrhosis

3. Tuberculosis

4. Excessive antibiotic therapy

5. Excessive X-ray therapy

7

Leukemia is a disorder of what tissues?

A disorder of the of the lymphoid tissues

8

Leukemia is characterized by uncontrolled proliferation of what cells and the reduction in what 2 cells?

Uncontrolled proliferation of abnormal WBCs and reduction in the number of RBCs and platelets

9

What 2 counts can detect leukemia?

1. Total WBC count

2. Differential WBC count

10

What is polycythemia?

Increase in the number of RBCs

11

Polychythemia may result from what 2 conditions?

1. Bone marrow cancer

2. Living at high altitudes where less oxygen is available

12

A decrease in RBCs result in what medical condition?

Anemia

13

Describe anemia in regard to oxygen-carrying capacity.

Anemia indicates decreased oxygen-carrying capacity of blood

14

The decreased oxygen-carrying capacity of blood, referred to as anemia, can arise due to what 2 causes?

1. Decrease in RBC number

2. Decreased hemoglobin content of RBCs

15

RBCs may suddenly decrease in number due to what 2 conditions?

1. Hemorrhage

2. Conditions destroying RBCs or hindering RBC production

16

How is a differential white blood cell count performed?

Counting 100 WBCs and classifying them based on type

17

Why is a differential white blood cell count important in regard to abnormality?

Abnormality in percentages of WBC types may indicate a problem and the source of pathology
