Let’s get to know all this important information about white blood cells Count (WBC) | Examination and Analysis of results .

Importance of white blood cells in our bodies

The human immune system is the organ that enables it to communicate with the surrounding world without getting sick day and night.

Millions of germs and viruses around us could have been fatal if we didn’t have an immune system.

The immune system is a compound of different organs, such as the skin, which separates the outside world from our bodies, but this device is also compounded by “soldiers” having the ability to distinguish the aggressive elements that invade the body and then eliminate them. These soldiers are white blood cells.

White blood cells begin to move and work and multiply whenever a foreign body (a bacteria or virus) enters the body. Therefore, if a blood test shows a large number of white blood cells, it can be concluded that the body is fighting a particular foreign body. A white blood cell examination can thus indicate a certain inflammatory process in the body.

There are several subtypes of white blood cells, such as lymphocytes, neutrophils and other types.

Each of these types has a specific function in identifying and eliminating the harmful agent, and we use this fact during a blood test to see not only if there is an increase in the number of white cells (during disease), but also to find out the type of white blood cells that are present in abundance. 

PEOPLE WHO AT RISK

It is true that this test shows the conditions in which the immune system (white cells) begin swells, but it can also show the reverse state in which the immune system fails.

Indeed, white blood cell testing is one of the tests required to diagnose AIDS. In addition, due to the fact that white cells are produced in the bone marrow (bone marrow – the inner part of the bone), bone marrow cancer (leukemia or leukemia) shows a very large increase in the number of white cells in the blood.

Related diseases

There are many diseases that can affect white blood cell testing. The main diseases are:


  • Diseases of fever of all kinds, caused by infection with a virus or bacterium.
  • Immune system failure.
  • Bone marrow cancer (leukemia).
  • Various cases of allergies and asthma.

When is the test done?

This test is usually not performed individually as an examination per se, but is performed as part of routine blood tests called “mass blood counting”.

This test can also be performed in all cases where a particular inflammation is suspected of having inflammation in the body, or when you have a fever, where the number of white blood cells is examined.

THE METHOD OF EXAMINATION

The talk here is about a normal and simple blood test, often performed by twitching in the area of the elbow cavity.

How to prepare the test ?

There is talk of a normal blood test here, so there is no need to make any special preparations (such as fasting). However, it should be noted that, in most cases, this test is performed as part of a series of tests that may require certain preparations, whether fasting or otherwise.

After the test

You can return to normal daily activity, immediately.

ANALYSIS OF RESULTS

The results of the white blood cell test appear in numbers and percentages, with the numbers indicating the absolute value of the number of white blood cells, while the percentages indicate the portion of each type of white blood cell in the total leukocytes.

The normal value of white blood cells range from 4,300 to 10,800 cells (the field can vary slightly between different laboratories).

High values (larger than the upper limit) of white blood cells usually indicate an infection, such as pharyngitis. Very high values may indicate bone marrow-induced leukemia.

Low values (below the minimum) indicate immune failure and a high risk of infection and contamination.
