WBC Full Form – What Is WBC, Definition, Meaning, Uses

WBC Full Form – What Is WBC, Definition, Meaning, and Uses will be discussed here. The immune system, a type of blood cell, is responsible for this existence in the body. The primary role of white blood cells (WBC) is to boost the body’s immunity and protect it from viral infections. It is white because it does not include RBCs. The human body’s bone marrow contains this substance. There are 4,000-11,000 WBC cells per microliter in the human body.

WBC’s full form is White Blood Cells. Leukocytes are another name for white blood cells. The white blood cell (WBC) is an essential component of the circulatory system. Platelets and bacteria make up white blood cells. WBCs make up only 1% of the blood, but they have a substantial impact. WBC is required for optimal health and protection from sickness and illness.

Neutrophils, eosinophils, lymphocytes, monocytes, and basophils are white blood cells. Each type protects the body from foreign diseases such as viruses, bacteria, fungi, and parasites in a different ways. WBCs, help guard the body against allergens, altered cells like cancer, and foreign substances like splinters, as well as remove dead cells, old red blood cells, and other detritus.

What is WBC?

White blood cells are just as significant as red blood cells in the human body. Our bodies’ white blood cells offer us the strength to fight diseases and protect us from severe infections.

Consider what would happen if the body’s supply of these cells was depleted. Obviously, without these cells, the body will be unable to fight infections, and numerous diseases will take over the person’s body. In this instance, it is critical to maintain the body’s average level of white blood cells.

A healthy person’s white blood cell count ranges from 4,000 to 11,000 per microliter. These cells keep our bodies safe from infection from the outside world. They also aid in the creation of antibodies as well as the destruction of infectious organisms and cancer cells. However, the number of these cells fluctuates for various reasons. When the number of white blood cells that protect the body from infection starts to decline, the risk of many significant diseases increases.

WBCs, commonly known as leukocytes, are found in the blood. White blood cells are generated in the bone marrow and come in five different kinds. White blood cells prevent clots from forming in your blood and work to eradicate illness microorganisms by creating antibodies. Furthermore, these cells aid in the battle against infections and strengthen the immune system.

A healthy person’s blood contains between 4000 and 11000 white blood cells per microliter. Leukemia, or blood cancer, is characterized by a shortage of white blood cells. You’re also in danger of AIDS and Hepatitis if you don’t have enough white blood cells. However, you can boost the number of white blood cells while maintaining a standard level with the help of various home treatments.

What are the different types of WBC in the body?

In our bodies, we have five different types of white blood cells (WBCs):


Neutrophils account for nearly half of the WBC count. They are your immune system’s initial line of protection, responding to germs and viruses. These are the primary cells that can be found in pus. They only live for around 8 hours after being released from the bone marrow, although they create 100 billion daily cells.


These are the two most critical ingredients and are crucial in the fight against bacteria. Eosinophils are essential protectors against germs and allergy viruses, but they can sometimes go beyond their intended function. This section also provides an immunological response to things like pollen.


They are only responsible for 1% of white blood cells (WBC whole). These cells help to develop an immune response to infections and are vital in asthma. Basophils secrete a substance called histamine, which induces airway irritation and constriction.


T lymphocyte T cells are in charge of killing foreign intruders. Unlike other types of WBC, B lymphocytes are responsible for humor immunity. These cells produce antibodies that help your body remember an illness and protect you if it happens again. B lymphocytes are an essential part of the immune system, although T cells also play a role.


Monocytes make up roughly 5% to 12% of white blood cells and are responsible for cleaning up dead cells. They get into the bloodstream and start acting like garbage trucks.

What is the purpose of a White Blood Cell Count Test?

A white blood cell count measures your body’s number of white blood cells (WBCs). Keeping your blood counts in a healthy range when they fluctuate is crucial. The following is a simple WBC calculation:

  • 9000-30000 for a newborn baby
  • 6200-17000 for children under the age of 18
  • In addition, children aged 5 to 10 outnumber adults by a factor of 5000 to 10,000.

Red blood cells, white blood cells, platelets, and plasma make up your blood. White blood cells make up only 1% of your blood, but they have a tremendous impact. Leukocytes are another name for white blood cells. They guard you against illness and disease. Consider white blood cells to be your immune system’s cells. They are perpetually at war, in a sense. They travel through your bloodstream to combat viruses, bacteria, and other foreign invaders that pose a health risk.

When your body is in danger and a specific location is targeted, white blood cells assist in destroying hazardous chemicals and preventing sickness. The bone marrow is where white blood cells are created. They build up in the blood and lymphatic tissues. Your bone marrow constantly produces white blood cells, which have a lifespan of 1 to 3 days.

What does a low WBC level imply?

The normal range for white blood cells (WBCs) per microliter of blood is between 4,000 and 11,000 per microliter. A WBC count of less than 4,000 per microliter (some laboratories suggest less than 4,500) may indicate that your body isn’t fighting the illness as effectively as it should be. Leukopenia is a condition that affects a tiny number of people.

White blood cell-related issues – WBC Full Form

Various factors can cause a low white blood cell count. This involves the ability of the body to restore cells when something is rapidly destroying them. Alternatively, when your bone marrow quits producing enough white blood cells to keep you alive. When your white blood cell count is low, you’re more susceptible to disease and infection, which can be dangerous to your health.

Your healthcare practitioner can perform a blood test to see if your white blood cell count is average. You may have leukemia if your count is abnormally low or high. White blood cell counts can be affected by various diseases and situations.

Immune System Deficiency This is frequently caused by treating diseases such as HIV/AIDS or cancer. Chemotherapy and radiation therapy for cancer can kill white blood cells, putting you at risk for infection.

Infection, A high-to-normal white blood cell count indicates the presence of an illness. To kill germs or viruses, white blood cells grow.

Myelodysplastic syndrome (MDS) is a type of cancer that affects the This disease results in aberrant blood cell production. The bone marrow includes white blood cells.

Leukemia malignancies, such as leukemia and lymphoma, can cause the bone marrow to overproduce abnormal blood cells. Infection or significant bleeding is far more likely as a result of this.

Myeloproliferative Disorder (MPD) is a type of myeloprolifer. This condition refers to a group of disorders that cause an increase in the generation of immature blood cells. This can result in an unbalanced mix of all types of blood cells in the bone marrow and an excess or lack of white blood cells in the circulation.

Medications Certain medications can raise or reduce the amount of WBC in the body.


Q1. What occurs if WBC is elevated?

They protect your body from illnesses and infections because they are made in your bone marrow. However, your body is likely infected or inflammatory if your white blood cell count is excessive. A high white blood cell count may, less frequently, be a sign of some blood malignancies or bone marrow issues.

Q2. Why is WBC so named?

Etymology. White blood cells get their name from how a blood sample looks on the outside following centrifugation. The buffy coat, a thin, generally white layer of nucleated cells located between the sedimented red blood cells and the blood plasma, contains white cells.

Q3. What is a normal WBC count?

Blood typically contains 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 109/L), or WBCs. Different labs may have slightly different normal value ranges. Some laboratories may test various specimens or utilize various metrics.
