what could be the cause of high white blood cell count?

A high white blood cell count usually indicates: An increased production of white blood cells to fight an infection. A reaction to a drug that increases white blood cell production. A disease of bone marrow, causing abnormally high production of white blood cells.

While having an elevated or abnormally high white blood cell count does not necessarily indicate leukemia, the source of the condition will need to be identified if it is found to exceed the levels and duration of a normal immune response to an infection.

When your body produces too many white blood cells it results in a blood disorder called leukocytosis. When your body isn't producing enough white blood cells to fight off infection it is called leukopenia.

White blood cells and platelets are usually high in sickle cell disease. Too many white blood cells (WBCs) and platelets can cause damage to the blood vessels. Also, high WBCs and platelets are associated with more severe complications of sickle cell disease such as stroke and acute chest syndrome.

Causes. Neutrophils are the primary white blood cells that respond to a bacterial infection, so the most common cause of neutrophilia is a bacterial infection, especially pyogenic infections. Neutrophils are also increased in any acute inflammation, so will be raised after a heart attack, other infarct or burns.

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.

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. But if you have certain illnesses like HIV or cancer, your white blood cell count can drop to very low levels.

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.

An increase in the total number of white blood cells in the blood.

Increased white blood cells in urine may indicate: A bacterial urinary tract infection. This is the most common cause of a high white blood cell count in urine. Inflammation of the urinary tract or kidneys.

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.

['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.']

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.

Increases in the WCC (leukocytosis) are most commonly a result of bacterial or viral infection, stress, drug administration or immune mediated disease. A decrease in the total numbers of white blood cells (leukopaenia) may be due to overwhelming bacterial or viral infection, bone marrow disease or endotoxaemia.

White blood cells help the body fight infections. Thus, if white blood cell levels are high, it can very well be an indication of an infection. “A bacterial infection is the most common kind that we see with high white blood cells,” says Dr.
