Hello and thank you for your question. An elevated white blood cell count can be caused by many factors. Most often, our concern would be that there is an infection, of some kind, and if that is the case then I would not recommend having an implant placed until it's normalized. Otherwise, you would need to be evaluated by your primary doctor to have this worked up.
Thanks for your inquiry, an elevated WBC can be many things and should be evaluated by your primary care doctor prior to proceeding with surgery, best of luck.
