What is White Blood Cell (WBC)

When mentioned the white blood cells (wbc) or leukocytes -if we say it in medical term-, then we can equate them with the armed forces in our body. White blood cells are the cells of the immune system responsible in defending the body against infectious disease and foreign materials. Every time the germ or infection enters the body, white blood cells snap to attention and race toward the scene.

White blood cells continue to be alert to signs of disease. When a germ does not appear, the white blood cells have a variety of ways by which they can attack. Some will produce protective antibodies that will defeat the germs. Others will surround and feed on bacteria. White blood cells have a rather short life cycle, living from a few days to several weeks.

Based on Wikipedia, There are several types of white blood cells. They all have much the same thing, but all differ in form and function. A main distinguishing feature is the presence of several leukocyte granules; white blood cells are often characterized as granulocytes or agranulocytes.

Normal WBC Count

What is a Normal White Blood Cell Count Range?

The normal white blood cell count range is 4300-10,800 white blood cells per cubic millimeter (cmm) of blood. In other words, it is 4.3 * 10 9 to 10.8 * 109cells per liter. The normal white blood cell level can be around 7000 WBCs per cubic millimeter of blood. Normally, there are

  • Neutrophils: 50-70 %
  • Lymphocytes: 25-35 %
  • Monocytes: 4-6 %
  • Eosinophils: 1-3 %
  • Basophils: 0.4-1 %

per cubic millimeter of blood. A leucocyte count around 3000-5000 is called leukopenia while in leukocytosis, it can be around 11000-17000. Some diagnostics usually round this off to 5.0 to 10.0 x 109 cells per liter. This means that a measurement that is slightly under or over the range is still considered to be normal.

A Normal WBC Levels

A WBC count that is more than the maximum normal limit of 10,800 is considered to be an indication of leukocytosis. However, a range from 11 to 17 is still considered to be mild. On the other hand, WBC counts that are below the minimum normal limit of 4,300 are now considered as leucopenia. Mild leucopenia ranges from 3,000 to 4,000.

High WBC Count

What does High White Blood Cell Count Mean?

High white blood cell count is an increase in disease-fighting cells (leukocytes) circulating in your blood. The threshold for high white blood cell count varies based on medical conditions, sex and age. If the numbers of leukocytes are more than 10,500 per-µliter of blood that generally considered a high white blood cell counts. High white blood cell count in urine may also mean a number of conditions like a urinary tract infection, bladder infection, kidney infection, kidney stones or tumor. High white blood cell count in children may indicate whooping cough, bacterial or viral infection, measles, allergy or leukemia.

Elevated White Blood Cell Count

An elevated white blood cell count can arise due to many medical reasons. High white blood cell count usually means there is increase in production of these cells to fight a possible infection. It may also means it is a reaction to a drug that helps in improving the WBC production. Bone marrow diseases may also cause high white blood cells count. Or it may also be due to an immune system disorder that leads to increase in white blood cell production.

The most common cause of elevated white blood cell count is due to infection. When the white blood cell count is elevated in older individuals for prolonged periods and no infection is present, this can mean an increased risk for cancer.

High White Blood Cell Count Symptoms

Any infection, inflammation or allergy can serve as an indicator of high white blood cell count symptoms. Bacterial infections, leukemia, trauma, inflammation, or stress are also high white blood cell count symptoms. An unusually high white blood cell count can indicate an infection, hypersplenism, bone marrow depression (drugs, radiation or heavy metal poisoning) or primary bone marrow disorders such as leukemia.

High White Blood Cell Count Causes

There are specific causes that may be lead to high white blood cell count. This may mean the following factors causes high blood cell count:

  • Acute lymphocytic leukemia
  • Acute myelogenous leukemia (AML)
  • Allergic reaction
  • Chronic lymphocytic leukemia
  • Chronic myelogenous leukemia
  • Drugs, such as corticosteroids and epinephrine
  • Hairy cell leukemia
  • Hemolytic anemia, which includes sickle cell anemia
  • Hodgkin’s disease and non-Hodgkin’s lymphoma
  • Infection such sinus infection or bladder infection
  • Inflammation due to a burn, skin rash or other tissue damage
  • Inflammatory bowel disease
  • Measles
  • Myelofibrosis
  • Other bacterial infections
  • Other viral infections
  • Physical or emotional stress
  • Polycythemia vera
  • Pregnancy
  • Rheumatoid arthritis
  • Smoking
  • Surgical spleen removal
  • Tuberculosis
  • Whooping cough

Low WBC Count

What does Low White Blood Cell Count Mean?

A low white blood cell count is a decreased number of white blood cells (leukocytes) in the blood. A low WBC count is referred to medically as leukopenia. When you have a low white blood cell count you may be immunosuppressed, which means that you are more vulnerable to potentially serious infections that do not go away or are hard to treat.

A low WBC count is usually discovered by your physician or health care provider during routine testing or through the course of diagnosis and treatment for an underlying disease, disorder or condition. A low WBC count can be serious because it increases your risk of developing a potentially life-threatening infection.

If you have a low WBC count, you will probably be advised by your medical professional to avoid situations that expose you to infectious and contagious diseases. Seek prompt medical care if you have a low WBC count and have signs of an infection, such as a fever, swollen lymph nodes, sore throat, or skin lesions.

Low White Blood Cell Count Symptoms

A low WBC count may be accompanied by other symptoms, which vary depending on the underlying disease, disorder or condition. Symptoms can include:

  • Fatigue
  • Recurrent infections that are difficult to treat
  • Shortness of breath
  • Weakness

Symptoms that might indicate a low WBC count can be serious because it increases your risk of developing a potentially life-threatening infection. Seek prompt medical care if you have a low white blood count and have signs of an infection, such as a fever, swollen lymph nodes, sore throat, or skin lesions.

Low White Blood Cell Count Causes

A low WBC count can be caused by a variety of diseases, disorders and conditions, as well as certain medications. In some cases a cause cannot be found. It often linked to problems with the bone marrow and the inability to make enough white blood cells. Autoimmune diseases that attack your white blood cells can also lead to a low WBC count (If you or someone you love is suffering from an autoimmune disorder then you might be interested in “How To STOP Autoimmune Disease In Weeks or Less“). Several different prescribed drugs, including chemotherapy, are known to decrease WBC production or destroy WBCs.

A low white blood cell count can be the result of infection, make an individual more susceptible to outside infections or allow multiplication of organisms within the body which would normally kept in check by a healthy immune system. so when white blood cell counts drop as a result of chemotherapy, radiation treatment, or certain types of cancer, it puts the patient in a vulnerable position. Without adequate protection from these disease-fighting cells, viruses and bacteria suddenly become much more serious threats.

A low WBC count can be caused by a variety of diseases, disorders and conditions, as well as certain medications. In some cases a cause cannot be found. A low WBC count can be due to a variety of different conditions that either destroy WBCs or inhibit their production in the bone marrow. These include:

  • AIDS
  • Aplastic anemia (condition in which the bone marrow makes insufficient blood cells)
  • Bone marrow disease (myelodysplastic syndromes)
  • Chemotherapy
  • Leukemia
  • Liver disease (hepatitis, cirrhosis, and liver failure)
  • Overactive spleen that destroys white blood cells
  • Radiation exposure
  • Rheumatoid arthritis (chronic autoimmune disease characterized by joint inflammation)
  • Systemic lupus erythematosus (disorder in which the body attacks its own healthy cells and tissues). Suffering from lupus? The Lupus Bible & Norton Protocol, STOP Lupus In Weeks or Less is the information you may want to know about how to overcome lupus.
  • Viral infection that affects bone marrow function
  • Vitamin deficiency
  • Widespread infection that depletes white blood cells
  • Medications that can reduce the number of white blood cells

A low WBC count can also be caused by medications or medical treatments that you are receiving for an underlying disease, disorder or condition, such as:

  • Antibiotics
  • Anticonvulsants
  • Antihistamines
  • Antithyroid drugs
  • Arsenic
  • Barbiturates
  • Chemotherapy drugs
  • Diuretics (“water pills”)
  • Radiation therapy
  • Sulfonamides

How to Increase White Blood Cell Count

Low white blood cell counts can be caused by a variety of factors, so get it checked out by your doctor. If, for example, you are receiving chemotherapy, your doctor can use drugs such as Neulasta to increase wbc counts.

Eat a lot of fruits and vegetables (however, if your white blood cell counts are lower than 1 k/µl , check with your doctor who may recommend avoiding raw foods). Get plenty of rest. Some extra vitamin C, zinc, and beta-carotene may be helpful, but don’t overdo it with the supplements, as this may be dangerous. (i.e. too much Airborne could give you dangerous levels of vitamin A). Sex activity or masturbation and moderate exercise can also increase wbc counts.

Considering to take supplement as a booster to your immune system?
