What Would Cause White Blood Count To Be High – Dear Mayo Clinic: My 16-year-old granddaughter was diagnosed with a low white blood cell count after two trips to the ER with migraine headaches, vomiting, and temporary vision loss. What can cause a low white blood cell count in someone her age? I’m worried it’s something serious and am wondering what other tests to do.
Answer: Many diseases and conditions can cause a low white blood cell count. Without more information it is difficult to say what the specific cause may be in your grandson’s situation. The low number is unlikely to be related to her migraines and other symptoms. It would be wise to have another blood test to see if the problem persists. Her doctor can decide if she needs further evaluation.

What Would Cause White Blood Count To Be High
Blood contains many components. In addition to white blood cells, which fight infection, red blood cells carry oxygen and platelets help blood clot. Bone marrow, the spongy tissue in bones, makes blood cells.
Types Of White Blood Cells And Their Functions
There are many types of white blood cells. Neutrophils fight fungal and bacterial infections. Lymphocytes protect the body from viral infections. Monocytes help get rid of dead or damaged tissue and regulate the body’s immune response. Eosinophils are white blood cells that fight disease. Basophils play a role in wound healing, infection, and allergic reactions.
One of the most common causes of low white blood cell count is a viral infection. These infections can sometimes temporarily disrupt the production of blood cells in the bone marrow, causing a decrease in the number of blood cells. The count usually returns as the body recovers from the infection. For most people, this temporary drop in blood cells has no long-term effects.
Some medications can cause low white blood cell counts because they can destroy white blood cells or damage the bone marrow. For example, taking antibiotics can sometimes cause an abnormal decrease in neutrophils, a condition known as neutropenia. With this in mind, it may be helpful for your granddaughter’s doctor to monitor any medications she is taking to see if their blood cell counts may be changing.
A variety of other conditions and disorders can also cause neutropenia. For an overview of this condition and more details on how it is diagnosed and treated, you can watch a Mayo Clinic video.
What Does A High White Blood Cell Count (leukocytosis) Mean?
The list of other possible causes for a person’s white blood cell count to drop is long. Autoimmune disorders, congenital disorders that affect the way the bone marrow works, disorders of the spleen, certain infectious diseases, cancer, and parasitic diseases can all cause low white blood cell counts.
A good next step for your grandchild is to have a complete blood count test. This test measures components in the blood. This test can help shed light on the specific type of white blood cells your grandchild is low in, as well as the results of measurements of other blood cells.
The other symptoms you mention — headaches, vision loss, and vomiting — should also be addressed through a physical exam, a review of your grandson’s family and medical history, and any additional tests the doctor suggests. Even if these symptoms are not related to her low white blood cell count, it is important to investigate and identify their underlying cause. — Carola Arndt, M.D., Pediatric Hematology/Oncology, Mayo Clinic, Rochester, Minn.

White blood cells known as leukocytes work to protect your body from infection. White blood cells circulate in your blood as part of your immune system and respond to injury or illness.
White blood cells do their job by warding off disease. Your white blood cells act as a command center, deploying other white blood cells to the site of infection to fight invading microbes.
Evaluation Of Patients With Leukocytosis
Your body’s white blood cells are the first line of defense against these invaders, as they secrete antibody proteins that bind to foreign organisms and ultimately kill them.
White blood cells circulate throughout the body and can pass through the walls of blood vessels and other tissues to reach the source of infection. In response to infection, your body’s white blood cells produce chemical signals that signal nearby white blood cells.
White blood cells, despite their name, are not actually colorless but instead appear very pale purple to pink when stained and viewed under a microscope. These microscopic cells are usually round and have a membrane running through the center (nucleus).
Only by using a microscope can one see individual white blood cells. Although most white blood cells are only 8 microns in size, they can range in size from 4 to 12 microns.

The rest of your blood contains only 1% white blood cells. The number of your red blood cells is much higher than the number of white blood cells in your body.
The soft tissue in your skeleton is where your white blood cells (bone marrow) are made. The thymus gland produces T cells, while the lymph nodes and spleen produce B cells (B cells). Both types of white blood cells are produced in large quantities by your body in your mid-teens and early 20s (T and B cells).
In the connective tissue of your bones you will find stem cells that give rise to white blood cells (bone marrow). The end result of this transformation is a large number of mature blood cells (blood cells); They are distributed throughout the body through the circulatory system.
People with low white blood cell counts are more likely to get infections (leukopenia). An abnormally high white blood cell count, or leukocytosis, can be a sign of an infection or a sign of a serious underlying medical condition, such as leukemia, lymphoma, or an immune disorder.

Med Surg: Immune Lab Values
White blood cells help fight infection and are essential for health and well-being. Changes in white blood cell levels can occur during infections, pregnancy, and some cancers.
A high white blood cell count may indicate that the immune system is working to fight off the infection.
It can also be a sign of physical or emotional stress. People with certain blood cancers may have high white blood cell counts.
A low white blood cell count may indicate that an injury or condition is destroying the body’s cells faster than it is making them, or that the body is producing too few of them.

White blood cells make up about 1% of all blood cells and are essential for the normal functioning of the immune system. White blood cells are also known as leukocytes.
The bone marrow is constantly producing white blood cells. They are stored in the blood and lymphatic system until they are needed in the body to fight infection or disease.
Each microliter of blood typically contains between 4,500 and 11,000 white blood cells, although this can vary by sex, age, and race.
When needed, monocytes travel to other organs, such as the spleen, liver, lungs, and bone marrow, where they transform into cells called macrophages.
Basophils: Function & Ranges
Macrophages are responsible for many functions, including removing dead or damaged tissue, killing cancer cells, and regulating the immune response.
An increase in white blood cells is called leukocytosis. It usually occurs in response to the following conditions:
Certain respiratory conditions, such as whooping cough or tuberculosis, can cause elevated white blood cell levels.
In some cases, all white blood cells are affected. However, some people have a specific disease in which only one type of white blood cell is affected.
Blood Differential Test
If the level of a certain type of white blood cell is elevated, it may be due to a specific trigger:
Occasionally, no cause can be identified for an increase in white blood cells. This is called idiopathic hypereosinophilic syndrome. It can cause serious complications, such as damage to the heart, lungs, liver, skin, and nervous system.
White blood cell levels increase significantly during a healthy pregnancy because the body is exposed to physical stress during this period. Levels begin to rise in the first trimester and continue to rise in the third trimester.
