4. White blood cells count
A white blood cell (WBC) count is a test that measures the number of white blood cells in the body.

5. Normal range of WBC count
The normal range of WBC count is : 3,500 to 10,500 White blood cells per mcL of blood in adults

6. Cases of abnormal WBC count
Causes of low WBC count :
autoimmune disorders
bone marrow disorders/damage
lymphoma
liver and spleen diseases
Causes of high WBC count :
smoking
tumors in the bone marrow
leukemia
pregnancy

8. Eosinophils count
The eosinophil count measures the amount of eosinophils in blood. Eosinophil are a kind of white blood cell that helps fight disease. 

9. Normal range of Eosinophils count
The normal range of Eosinophils count is :
0.02 – 0.5×10 9/L = ( 1 – 6 % )

10. Cases of abnormal Eosinophils count
Causes of low Eosinophils count :
Cushing syndrome
Bloodstream infections (sepsis)
Treatment with corticosteroids. 
Causes of high Eosinophils count :
Allergic disorders
Infections by parasites
Certain cancers

12. Neutrophils count
The Neutrophils count measures the amount of Neutrophils in blood . Neutrophils are a very important defense against most types of infection.  

13. Normal range of Neutrophils count
The normal range of Neutrophils count is : 2.0 – 7.0×10 9/L = (40 – 80 % )

14. Cases of abnormal Neutrophils count
Causes of low Neutrophils count :
Problem in production of Neutrophils in bone marrow
Infection
Nutritional deficiency
Causes of high Neutrophils count : 
Acute infections
Noninfectious inflammation
poisoning with lead, mercury, 
Acute hemorrhage

16. Basilophills count
The Basilophills count measures the amount of Basilophills in blood . Basilophills are responsible for inflammatory reactions during immune response.

17. Normal range of Basilophills count
The normal range of Basilophills count is :
0.02 – 0.1×10 9/L = (< 1 – 2 % )

18. Cases of abnormal Basilophills count
Causes of low Basilophills count :
Pregnancy
Stress
Hyperthyroidism
Causes of high Basilophills count :
  physical stress
recent splenectomy

20. Monocytes count
This test measures the amount of Monocytes in blood. Monocytes are a type of white blood cell (WBC). This test is used to evaluate and manage blood disorders

21. Normal range of Monocytes count
The normal range of Monocytes count is : 0.2 – 1.0×10 9/L = ( 2 – 10 % )

22. Cases of abnormal Monocytes count
Causes of low Monocytes count :
bloodstream infection
Chemotherapy
bone marrow disorder
Causes of high Monocytes count :
chronic infections
autoimmune disorders
blood disorders
certain cancers

This test measures the amount of lymphocytes in blood. A lymphocyte is one of the subtypes of white blood cell in a vertebrate's immune system. Lymphocytes include natural killer cells  T cells  and B cells 

25. Normal range of Lymphocytes count
The normal range of Lymphocytes count is : 1.0 –3.0×10 9/L = (20 – 40 % )

26. Cases of abnormal Lymphocytes count
Causes of low Lymphocytes count :
Acquired lymphocytopenia
Inherited lymphocytopenia
Viral and bacterial infections
Causes of high Lymphocytes count :
Acute lymphocytic leukemia
Chronic lymphocytic leukemia
Cytomegalovirus (CMV) infection
