Answer

We can explain to you the various possible causes of a high white blood cell (WBC) count, but you need to be investigated by your own doctor, who knows you, your medical history and can treat you appropriately only after a diagnosis has been made.

Causes of High White Blood Cell Count

White blood cells (leukocytes) help fight infection in your body. A normal white blood cell count is between 4,500 and 10,000 cells per microliter. A high white blood cell count (leukocytosis) isn't a specific disease. But it may indicate an underlying problem that requires medical evaluation. There are several possible causes for a high white blood cell count.
Causes of a high white blood cell count include: Infection - Severe physical or emotional stress - Use of certain medications, such as corticosteroids, antibiotics or anti-seizure drugs - Chronic bone marrow diseases such as a myeloproliferative disorder ( The chronic myeloproliferative disorders are polycythemia vera (PV), myelofibrosis (MF), essential thrombocythemia (ET), chronic myelogenous leukemia (CML) ) - Acute or chronic leukemia - Tissue damage, such as from burns. 

A Low-grade fever is not serious unless it becomes chronic with accompanying symptoms. The body uses this fever to fight infection, whether it be viral or bacterial. It is not necessary to treat a low-grade fever with medication. It is important to be aware, as mentioned above that a high white count does not identify a specific problem. Instead, it may indicate an underlying condition and should be evaluated by your doctor.

Treatments for High White Blood Cell Count

The treatment for leukocytosis, or a high white blood cell count, depends upon the cause. Only an investigation by your doctor can identify the appropriate treatment.

The tests performed to find the cause for an elevated white blood cell count will vary depending on the individual, his/her clinical presentation, and his/her medical history. Sometimes blood tests or an investigation of the medications an individual is taking may be enough to determine the cause. Individuals who present with symptoms or other abnormal laboratory tests that are concerning for a bone marrow disorder may require a bone marrow biopsy, a procedure used to remove soft tissue from inside the bone, for further analysis.

If you are concerned about a high white blood cell count, talk to your doctor to find out what tests might be appropriate for you.

I went to the doctor last week because for months now I felt run down and soo tired. He drew blood and my WBC was elevated- 12.9 and my vitamin D level was Low- 18.
I go back for more blood work today. I am scared, even though I know I shouldn't be. Besides being too tired to do anything, I am fine.

Could my vitamin D levels and high WBC be a symptom of a single cause???

In addition to a high white blood cell count, your health care provider will also check your blood for low white blood cell counts. Sometimes this is caused by some chemotherapy drugs, which can cause damage to your bone marrow.

My white blood cell count is a little elevated. It is 13,500. I have a yeast infection. Could this cause my white blood count to be elevated?
I read that a viral infection can lower white blood cell count but I didn't find anything on how a yeast infection would raise it.

Yes, fungal/yeast infections, as well as bacterial, viral, and parasitic infections, can cause elevations in white blood cell count.

Other bone marrow diseases or immune system disorders, as well as infection, stress, and medications, can also cause a high white blood cell count. It sounds like you have taken the right steps towards finding out the cause of your high white blood cell count, and especially because you have been feeling sick over the past few months, we encourage you to follow up with your doctor for the results of your tests, as well as for appropriate treatement.

June Chen, MD wrote 9 weeks 3 days ago

Based on your comment, it seems that your doctor believes your high white blood cell count is due to infection. Antibiotics, such as sulfamethoxazole, fight bacterial infections. As long as the bacteria causing your infection is sensitive to the antibiotic your doctor prescribed, then your high white blood cell count should decrease.

As mentioned above, there are many possible causes of leukocytosis and strategies for prevention would vary depending on the cause. For example, antibiotics may treat or prevent the leukocytosis associated with infection; antihistamines may prevent the leukocytosis associated with allergy; and controlling stress may prevent the leukocytosis associated with emotional or physical stress.
