That is a high WBC, but it could be a lot of different things. The main question, is what did your doctor say. Is he or she running any other tests on you?
I would get some further testing to see if they can come up with a definite diagnosis for you. Please let us know how you are doing. Take Care.
It is slightly elevated, but that doesn't say much of anything. Infections and viruses can cause a slight elevation. What are the rest of your lab results? That can point us in a direction.
