Brief Answer:
Lots of causes - clinical information is crucial

Detailed Answer:
Hello,
I'll try to give you some idea about it although assessment of a single laboratory test without appropriate clinical context is - almost always - not very useful.
You've got increased white blood cells, particularly the granulocytes. Lymphocytes are on the lower normal range.
The differential diagnosis of white blood cells elevation is too broad to be fully analyzed here. I'll describe some common causes instead. If you'd provided the relevant clinical information, it would be much easier fro me to interpret the findings and more informative for you.
The most common cause of white blood cell (WBC) elevation (due to granulocytes elevation) is bacterial infection. This includes pneumonia, pharyngitis, pyelonephritis etc.
Inflammatory conditions in general (besides infections) may also elevate the WBC count. These include various types of vasculitis, rheumatoid arthritis etc
Certain drugs increase the number of WBC in peripheral blood. Corticosteroids are a well-known example of such a drug.
Cancer may present with high WBC as well. Hematologic malignancies also. Hodgkin's lymphoma or chronic myelogenous leukemia.
Excision of the spleen (Splenectomy) lets more WBC circulate and increased counts appear.
I hope I've given you some insight!
If you need more information on the subject, I'll be glad to provide it for you.
It would be very helpful though if you'd mention the clinical details like
- why did you do this test?
- did you have any symptoms?
- do you take any drugs?
- relevant medical history
With the above information, I would be able to give you a more specific answer.
Kind Regards!
