I’m 22 years old and I am in pretty good health. I am a little bit overweight by 8 lbs for my target height but I stay pretty active. For the past couple years after high school I have been suffering from Allergy and Sinus problems, developing a Sinus Infection about once a year. For the last few months my allergies have been bothering me and at the beginning of last month I got very sick. I felt ok all day, but when I got home from work a fever and chills hit me out of nowhere. It felt like a normal cold but I felt really weak and I had two really high fevers in a row. I went to the doctor and they initially thought it was Mono and also gave me some anti-biotic for the possibilities of sinus problems. I had a CBC done to see if I had mono. When they test results came back my WBC was low, but "everything else looked healthy". This kind of scared me and they sent me back for another CBC. By the time I went for my second CBC I was starting to feel better. This time my WBC was "still kind of low but coming back to normal and everything else looked healthy". By this time I was feeling back to normal, but I still worried about my low WBC count. I asked my doctor about the possibility of Leukemia or anything like that and she said "no no no, everything else on the blood test came back okay, everything else was healthy, if it was something like that everything else would also be out of wack" my doctor suggested that I could possibly had a sinus infection and the flu or vise versa flu brought on sinus infection. I was okay for 2 weeks, then my head started to get congested (pollen count was high) so I went back to the doctor (a new doctor, my old one is moving out of town) to get on some sinus meds. I told her of my history and she is having me take some more tests to see where I am physically (mainly to do with cholesterol level because she is really big on preventing diabetes) including another CBC. So I have yet to hear back from the tests, but starting Monday I have started to develop a sinus infection and I’m afraid it could be something worse.

Are there other factors in a CBC that would signify a problem like leukemia? Like platelet levels or something like that? Because my doctor said everything else on the test was fine, it was just the WBC count was a little low.
