what causes very high white blood cells?
20232
The main causes of elevated white blood cells include: To fight a viral, fungal, bacterial, or parasitic infection. A negative reaction to a drug that triggers an immune and white blood cell response. Disease or malfunction that causes the bone marrow to overproduce white blood cells.
35444
A high hematocrit with a high RBC count and high hemoglobin indicates polycythemia. Some examples of causes of a high hematocrit include: Dehydration—this is the most common cause of a high hematocrit.
1085652
When your body produces too many white blood cells it results in a blood disorder called leukocytosis.
616786
If your white blood cell count is higher than normal, you may have an infection or inflammation. Or, it could indicate that you have an immune system disorder or a bone marrow disease. A high white blood cell count can also be a reaction to medication. Platelet count.
52431
A high white blood cell count may indicate that the immune system is working to destroy an infection. It may also be a sign of physical or emotional stress. People with particular blood cancers may also have high white blood cells counts.
270436
In response to acute infection, trauma or inflammation, the number of WBCs increases and in some diseases, such as sepsis, the increase in WBC is so dramatic that resembles leukemia (leukemoid reaction).
230488
An increased level of white blood cells (WBC) often is found in patients with lung carcinoma either at the time of diagnosis or during the course of the disease. 1 It may be caused by one or more factors, such as concomitant infections, bone marrow metastasis, or administration of corticosteroids.
223546
The most common causes of elevated white blood cell counts are infections and inflammation. Some cases of leucocytosis are the result of an immune reaction. A small number of cases are caused by a blood cancer. Treatments for high white blood cell counts typically focus on addressing the underlying disease.
43580
When you get sick, your white blood cell count is higher than normal. This is because your body is releasing more of these cells to fight the infection.
843803
Though it varies between individuals, a high white blood cell count (leukocytosis) is usually considered to be anything above 11,000 cells per μl of blood in an adult. This can be related to: Infection. Bone marrow disease.
44645
The peripheral white blood cell count can double within hours after certain stimuli because of the large bone marrow storage and intravascularly marginated pools of neutrophils. Stressors capable of causing an acute leukocytosis include surgery, exercise, trauma, and emotional stress.
1180603
Your white blood cell count may be high because your body is fighting an infection. But other things can cause it, such as some medicines, burns, an illness, or other health problems. When your doctor sees that your white blood cell count is high, he or she will try to find out why, and then treat the cause.
456667
Typically, white blood cell count is elevated during pregnancy, with the lower limit of the reference range being around 6,000 cells per μl and the upper limit around 17,000 cells per μl. 5. The stress imposed on the body through pregnancy causes this rise in white blood cells.
867106
Stress levels increase white blood cell count This indicates a connection between elevated stress levels and the body's production of what are known as inflammatory leukocytes, a particular variety of white blood cell. Normally, inflammatory leukocytes are the body's defense system against infection and disease.
1214220
Neutrophils, which account for about 70% of white blood cells, can increase in response to bacterial infections as well as to physical or emotional stress. A high lymphocyte count may occur when there is a viral or bacterial infection.
960521
['An insufficient supply of healthy red blood cells (anemia)', 'A large number of white blood cells due to long-term illness, infection or a white blood cell disorder such as leukemia or lymphoma.', 'Vitamin or mineral deficiencies.', 'Recent or long-term blood loss.']

This is a key factor that causes imbalance due to haemolytic change during pregnancy. The white blood cell count increases when the immune system is fighting an infection. The high population of these cells indicates a requirement for support of the immune system.
