My husband has been in the hospital for one wk with a wbc of 2100 and a fever.They are giving him double antibiotics  however they cannot seem to pinpoint the infection. He is a cancer survivor  2yrs.I am thinking sepsis because sometimes it can be misdiagnosed.
HI, thanks for using Chat Doctor Sepsis is a serious infection where toxins have spread through the blood stream. The high white cell count may mean he does have sepsis, but the original source may not be difficult to pinpoint. He would need blood test including a blood culture, urine tests, chest x-ray. The blood culture may need to be repeated to rule out infective endocarditis which is an infection involving the heart. It is treated with antibiotics hope this helps
