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.
What happen if white blood cells are high?
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.
Is low white blood count serious?
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 WBC count and have signs of an infection, such as a fever, swollen lymph nodes, sore throat, or skin lesions.
What is a dangerous white blood cell count?
In general, for adults a count of more than 11,000 white blood cells (leukocytes) in a microliter of blood is considered a high white blood cell count.
Is a high white blood cell count a sign of cancer?
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 should I be worried about high WBC?
A high white blood cell count isn’t a specific disease in itself, but it can indicate an underlying problem, such as infection, stress, inflammation, trauma, allergy, or certain diseases. That’s why a high white blood cell count usually requires further investigation.
What diseases cause high white blood cell count?
The following conditions can cause white blood cell counts to be high:
- Viral or bacterial infection.
- Excessive physical or emotional stress (such as fever, injury, or surgery)
- Immune system disorders such as lupus or rheumatoid arthritis.
- Thyroid problems.
What is the most common reason for low white blood cell count?
A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.
Can stress cause low white cell count?
In addition, stress decreases the body’s lymphocytes — the white blood cells that help fight off infection. The lower your lymphocyte level, the more at risk you are for viruses, including the common cold and cold sores.
What cancers cause low white blood cell count?
Low white blood cell count.
Cancers that affect the blood and bone marrow can also lower the count. These types of cancers include leukemia, lymphoma, and multiple myeloma.
What is an alarming WBC count?
Normally you have between 4,000 and 11,000 WBCs per microliter of blood if you aren’t pregnant. Anything higher is considered leukocytosis. WBC counts between 50,000 and 100,000 per microliter usually mean a very severe infection or cancer somewhere in the body.
Is it dangerous if white blood cells are high?
White blood cell counts that are too high or too low may be dangerous, depending on the cause. Infection can cause spikes, as well as blood cancers and other conditions. White blood cells (leukocytes) make up about 1% of our blood and they help protect the body against illness and disease.
What is a concerning white blood cell count?
How many white blood cells (WBCs) someone has varies, but the normal range is usually between 4,000 and 11,000 per microliter of blood. A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should.
Does cancer show up in blood work?
With the exception of blood cancers, blood tests generally can’t absolutely tell whether you have cancer or some other noncancerous condition, but they can give your doctor clues about what’s going on inside your body.
Can thyroid affect white blood count?
The high levels of thyroid hormone can cause a decrease in the total count of one type of white blood cell known as neutrophils. Very low counts of neutrophils often increase the risk of getting a severe infection.
Does colon cancer cause high white blood cells?
Our findings demonstrate that an elevated WBC is associated with an increase in both the mortality and incidence rates of colon cancer.
