What Is a Leukocyte Count?

White blood cells are a very important type of blood cells in human blood. White blood cells carry many important tasks in the human body. It has the role of phagocytosing foreign bodies and producing antibodies, the ability to heal body damage, the ability to resist invasion of pathogens, and immune resistance to diseases. In fact, white blood cells can also be subdivided into five types. The use of instruments or artificial methods to count these five types of cells separately is called white blood cell count. Among these five types of white blood cells, neutrophils account for 0.5 to 0.7, lymphocytes account for 0.2 to 0.4, monocytes account for 0.03 to 0.08, eosinophils account for 0.01 to 0.05, and basophils do not exceed 0.01. When the body is unwell, it is often manifested by significant changes in the number of white blood cells. Therefore, in many cases, a routine blood test is required when visiting a hospital. Nowadays, more routine instruments are used for routine blood tests in hospitals. There are often more than 20 indicators. Many times, doctors first pay attention to whether the number of white blood cells (WBC) has changed. Leukocytes are very special and important cells, so it's important to know about them.

Clinical significance of white blood cell count

The increase in the total number of white blood cells is a matter of great concern. This increase has both physiological and pathological factors. We don't have to worry about the temporary increase caused by physiological factors, but we must not ignore the pathological increase. Of course, the significant decrease in the number of white blood cells is also a problem that cannot be ignored. Increasing and decreasing the number of white blood cells often has the following conditions:

Physiological increase

Newborn, late pregnancy, childbirth, after strenuous exercise.

2. Pathological increase

Purulent bacterial inflammation, uremia, leukemia, tissue damage, surgical trauma, etc.

3. reduce

Viral infection, typhoid fever, paratyphoid fever, black fever, malaria, aplastic anemia, after chemotherapy and radiotherapy, etc.
