Differential WBC count

LAB6
Differential White Blood Cells Count (Differential Leucocytes Count)
The differential W.B.Cs count is a part of the C.B.C tests and is the most important, includes the preparation, staining, and examination of a thin film of blood smear on a glass slide.
The total W.B.Cs count is not necessarily indicative of the severity of a disease, since some done, to exam the presence the different type of W.B.Cs
There are 5 types of W.B.Cs are normally found in the blood:-
1- Neutrophils
2- Eosinophils
3- Basophils
4- Lymphocytes
5- Monocytes

1- Neutrophils
Has very tiny light staining granules (difficult to see) the nucleus is multi-lobed. These cells have a phagocytosis work against toxins and viruses.
In the normal blood smear this type is the most numerous. Normally neutrophils account = 52 – 721 of all W.B.Cs.
Above normal range, this due to an acute infection such as rheumatic fever burns. While if the count is less normal, it may be due to virus’s infection ex: influenza, hepatitis, Rubella or lack of vit.B12 (folic acid).
2- Eosinophils
