White blood cells are an important component of your blood system, which is also made up of red blood cells, platelets, and plasma.
The white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis.
Although your white blood cells account for only about 1 percent of your blood, their impact is significant. White blood cells, also called leukocytes, are essential for good health and protection against illness and disease.
White blood cells are produced inside the bone marrow and stored in your blood and lymphatictissues. Because some white blood cells have a short lifespan of one to three days, your bone marrow is constantly producing them.
Types of white blood cells
Among your white blood cells are:
Among your white blood cells are:
Monocytes. They have a longer lifespan than many white blood cells and help to break down bacteria.
Lymphocytes. They create antibodies to defend against bacteria, viruses, and other potentially harmful invaders.
Neutrophils. They kill and digest bacteria and fungi. They are the most numerous type of white blood cell and your first line of defense when infection strikes.
Basophils. These small cells appear to sound an alarm when infectious agents invade your blood. They secrete chemicals such as histamine, a marker of allergic disease, that help control the body's immune response.
Eosinophils. They attack and kill parasites, destroy cancer cells, and help with allergic responses.
Problems affecting white blood cells
Your white blood cell count can be low for a number of reasons—when something is destroying the cells more quickly than the body can replenish them or when the bone marrow stops making enough white blood cells to keep you healthy. When your white blood cell count is low, you are extremely susceptible to any illness or infection, which can spiral into a serious health threat.
Your health care provider can see whether your white blood cell count is normal through a blood test known as the complete blood count. If your count is too low or too high, you may have a white blood cell disorder.
A number of diseases and conditions may influence white blood cell levels:

A number of diseases and conditions may influence white blood cell levels:
Weakened immune system. This is often caused by illnesses such as HIV/AIDS or by treatments related to cancer. Cancer treatments such as chemotherapy or radiation therapy can destroy white blood cells and leave you vulnerable to infection.
Myelodysplastic syndrome. This condition causes abnormal bone marrow cell production.
Myelodysplastic syndrome. This condition causes abnormal bone marrow cell production.
Cancer of the blood. Cancers including leukemia and lymphoma can cause uncontrolled growth of an abnormal type of blood cell in the bone marrow, resulting in a greatly increased risk for infection and or serious bleeding.
Myeloproliferative disorder. This disorder refers to various conditions that trigger the excessive production of immature blood cells. This can result in an unhealthy balance of all types of blood cells in the bone marrow and too many or too few white blood cells in the blood.Other conditions, such as extreme physical stress caused by an injury or emotional stress, can trigger high white blood cell levels, as can inflammation, labor or the end of pregnancy, smoking, or even extreme exercise.
Supplements can play a big role in boosting immune function and white blood cell counts,The following are among 174 ingredients that form trevo which are essential for white blood cells counts.
Vitamin C
Foods that boost your immune system containing vitamin C increase the production of infection-fighting white blood cells and antibodies and increases levels of interferon, the antibody that coats cell surfaces, preventing the entry of viruses. Vitamin C reduces the risk of cardiovascular disease by raising levels of HDL (good) cholesterol while lowering blood pressure and interfering with the process by which fat is converted to plaque in the arteries. As an added perk, persons whose diets are higher in vitamin C have lower rates of colon, prostate, and breast cancer.
Vitamin E
Vitamin E stimulates the production of natural killer cells, those that seek out and destroy germs and cancer cells. Vitamin E enhances the production of B-cells, the immune cells that produce antibodies that destroy bacteria. Vitamin E supplementation may also reverse some of the decline in immune response commonly seen in aging. Vitamin E has been implicated in lowering the risk of cardiovascular disease. In the Harvard School of Public Health study of 87,000 nurses, Vitamin E supplementation was shown to cut the risk of heart attacks by fifty percent.
Zinc
This valuable mineral increases the production of white blood cells that fight infection and helps them fight more aggressively. It also increases killer cells that fight against cancer and helps white cells release more antibodies. Zinc supplements have been shown to slow the growth of cancer. Zinc increases the number of infection-fighting T-cells, especially in elderly people who are often deficient in zinc, and whose immune system often weakens with age. The anti-infection hype around zinc is controversial. While some studies claim that zinc supplements in the form of lozenges can lower the incidence and severity of infections, other studies have failed to show this correlation.
Garlic
Garlic
One of the most flavorful foods that boost your immune system stimulates the multiplication of infection-fighting white cells, boosts natural killer cell activity, and increases the efficiency of antibody production. The immune-boosting properties of garlic seem to be due to its sulfur-containing compounds, such as allicin and sulfides. Garlic can also act as an antioxidant that reduces the build-up of free radicals in the bloodstream. Garlic may protect against cancer, though the evidence is controversial. Cultures with a garlic-rich diet have a lower incidence of intestinal cancer. Garlic may also play a part in getting rid of potential carcinogens and other toxic substances. It is also one of the most heart-friendly foods that boost your immune system since it keeps platelets from sticking together and clogging tiny blood vessels.
Selenium
This mineral increases natural killer cells and mobilizes cancer-fighting cells. Foods that boost your immune system containing selenium are tuna, red snapper, lobster, shrimp, whole grains, vegetables (depending on the selenium content of the soil they’re grown in), brown rice, egg yolks, cottage cheese, chicken (white meat), sunflower seeds, garlic, Brazil nuts, and lamb chops.
Omega-3 Fatty Acids
The omega-3 fatty acids in flax oil and fatty fish (such as salmon, tuna, and mackerel) act as immune boosters by increasing the activity of phagocytes, the white blood cells that eat up bacteria. Essential fatty acids also protect the body against damage from over-reactions to infection. When taking essential fatty acid supplements, such as flax or fish oils, take additional vitamin E, which acts together with essential fatty acids to boost the immune system.
