What is High White Blood Cell Count?

The medical term used for the presence of high white blood cell count in a person is Leukocytosis. This condition is further divided into five subcategories and these categories depend on the severity of the condition. The function of white blood cells or leukocytes is to protect the immune system of a person and to fight against bacteria, fungi and virus.

Leukocytes are again divided into 5 types and they are ai??i?? eosinophils, neutrophils, basophils, lymphocytes and monocytes and the bone marrow is responsible to produce these blood cells. Neutrophilla is a condition caused when the count of neutrophils increases.

Eosinophillia is a condition caused due to an increased count of eosinophils and similarly monocytosis, basophilis and lymphocytosis occur due to an increase in the count of monocytes, basophils and lymphocytes. Read to know more about the causes and treatment. This article also explains about high white blood cell count in children, its causes and treatment too.


The condition of increased number of white blood cell count can be caused due to an internal infection in the body. Certain diseases of bone marrow, due to drugs and immune system disorders can result in this condition. Tissue damages due to burns, fungal, parasitic, viral and bacterial infections can also result in causing this condition. The following are certain medical conditions in children that can result in leading to this condition.

  • Hemorrhage
  • Fever
  • Allergies
  • Chronic or acute leukemia
  • Stress
  • Pneumonia
  • Rheumatoid
  • Measles
  • Whooping cough
  • Tuberculosis
  • Myelofibrosis and
  • Polycythemia vera

Read to know about these causes in detail.

  • Increase in the production of the white blood cells may be due to an infection. In order to fight the infection the bone marrow may produce too many WBCs in the blood.
  • Certain drugs, diseases of the bone marrow and immune system disorders may cause abnormal production of WBCs.
  • Viral, bacterial, fungal infections, parasitic and tissue damage caused due to burns also can increase the production of leukocytes.
  • Sometimes, medical conditions like allergies, fever, hemorrhage, cancer, emotional or physical stress, acute or chronic leukemia, pneumonia, tuberculosis, rheumatoid arthritis, measles, myelofibrosis, polycythemia vera and whooping cough can increase the count of the white blood cells.
  • The increase in the count of WBC is very common in pregnant women and this may be caused due to any disease and this can also result in fever.
  • The raised count of white blood cells in urine can be caused due to bacterial infection of the urinary tract and bladder and kidney infection.

The following are a few medications or drugs that can result in causing this condition.

  • Chloroform
  • Lithium
  • Corticosteroids
  • Beta antagonist
  • Anti-seizures
  • Aspirin and
  • Quinine

This condition can also be seen in pregnant women and they may suffer from infections and fever. Bladder, kidney, urinary tract and bacterial infections can also cause an increase in the count of white blood cells.

Common Treatment Options

Treatment for this condition depends on its causes and it involves various diagnostic tests. These tests will help in finding out the exact cause of the increase in the count of WBCs.

This condition varies from person to person and is caused due to the usage of certain medications, then it is recommended to discontinue their usage.

  • Avoid the intake of medications that can result in causing this condition.
  • Follow a healthy diet and include fresh fruits and vegetables as they will help in improving the immune system.

The following article explains about the presence of increased number of leukocytes in children and its causes.

Leukocytes in Children

The condition of high white blood cell count in children is very common and this can occur due to poor immune system in the body. This condition can vary according to the child’s age and gender. There are higher chances for the newborn babies to suffer from this condition which may gradually decrease with the age. Read on to know the causes and treatment for this condition.

Causes of High WBC’s Count

There are several reasons that lead to the condition of increased number of white blood cells in children and the following are a few of them.

  • If a child suffers from elevated leukocytes count due to skin rashes and fever, then it can be due to measles.
  • Measles are generally contagious and can occur due to viral infections that mainly involve the respiratory tract.
  • There are several other symptoms of measles such as puffy eyes, cough, runny nose, sore throat and whooping cough that can also lead to this condition.
  • Many children suffering from acute lymphocytic leukemia, a cancer that affects the blood and bone marrow are more prone to this condition.
  • An immune system disorder can also lead to the condition of elevated leukocytes count in children.
  • Corticosteroids and epinephrine are certain medications that can cause a few side effects that can further lead to this condition.
  • Certain bacterial and viral infections or burns can also lead to the rise in the leukocytes count.

Treatment Options for Children

  • The condition of increased white blood cell count in children can be detected through certain laboratory tests that diagnose the cause for this condition. Treatment for this condition mainly depends on the test results.
  • If this condition occurs due to infections caused by bacteria, fungi etc, then the doctor may prescribe certain antibiotics.
  • You may have to stop the usage of the medications that lead to this condition.
