Leukocytosis
Leukocytosis is the increase in total leukocyte (WBC) count. It occurs in conditions such as:
1. Infections
2. Allergy
3. Common cold
4. Tuberculosis
5. Glandular fever.
Leukemia
Leukemia is the condition which is characterized by abnormal and uncontrolled increase in leukocyte count
more than 1,000,000/cu mm. It is also called blood cancer.
Leukopenia
Leukopenia is the decrease in the total WBC count. It occurs in the following pathological conditions:
1. Anaphylactic shock
2. Cirrhosis of liver
3. Disorders of spleen
4. Pernicious anemia
5. Typhoid and paratyphoid
6. Viral Infections.
Neutrophilia
Neutrophilia or neutrophilic leukocytosis is the increase in neutrophil count. It occurs in the following conditions:
1. Acute infections
2. Metabolic disorders
3. Injection of foreign proteins
4. Injection of vaccines
5. Poisoning by chemicals and drugs like lead, mercury, camphor, benzene derivatives, etc.
6. Poisoning by insect venom
7. After acute hemorrhage.

Eosinophilia is the increase in eosinophil count and it occurs in:
1. Asthma and other allergic conditions
2. Blood parasitism (malaria, filariasis)
3. Intestinal parasitism
4. Scarlet fever.

Basophilia is the increase in basophil count and it occurs in:
1. Smallpox
2. Chickenpox
3. Polycythemia vera.
Monocytosis
Monocytosis is the increase in monocyte count and it occurs in:

Eosinopenia
Decrease in eosinophil count is called eosinopenia. It occurs in:
1. Cushing’s syndrome
2. Bacterial infections
3. Stress
4. Prolonged administration of drugs such as steroids, ACTH, epinephrine.
Basopenia
Basopenia or basophilic leukopenia is the decrease in basophil count. It occurs in:
1. Urticaria (skin disorder)
2. Stress
