<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had high blood pressure 148104 last week. I am taking blood pressure meds right now which contain a diuretic to treat my edema. My doctor sent me for several blood tests including a CBC. I have an elevated WBC count yet no infection - what could be the cause?  <response>: A high TLC count is not always a marker of obvious infection many times you have a subclinical infection and u dont know.g. u have eaten some food outside and u get a small infection the body will fight it, even if you dont develop obvious infection even if you have allergies, the TLC may be a little high even high BP has marginally raised below fluid intake is also a cause would suggest u dont worry about itcant really say, u havent mentioned the actual counthave it repeated in 15 days times for entry low salt diet too if u have edema associated with hypertension best of luck
