Normal Count:-

types of WBCS

                        Leucocytes

Granulocyte                              ┃ Agranulocyte

-> Neutrophil (3000-6000/μL) ┃  -> Monocyte (300-600/μL)

-> Eosinophils (150-300/μL)    ┃ -> Lymphocyte (1500-2700/μL)

-> Basophil (10-100/μL)           ┃ 

At Birth:- 20,000/μL.

Adult:- 4,000-11,000/μL

Leucopenia:- TLC count decrease less than < 4,000/μL

Causes:- 

(1). Starvation (due to hunger)

(2). Typhoid Fever

(3). Viral infection

(4). Bone marrow suppression

Leukocytosis:- T.L.C count increase above 11,000/μL.

Causes:- 

1). Newborn(Normal 20,000/μL) 

2). In the evening (minimum count seen in the morning).

3). High Exercise

4). After injection of epinephrine norepinephrine

5). Stress

6). Pregnancy

7). Administration Eg. Steroid

8). Any pyogenic or pyrogenic infection.

Leukemia (cancer condition):- Leukemia is a cancerous condition of blood in which T.L.C is usually more than > 50,000/μL.
