What Causes Elevated White Blood Cells?

Today, I went for some blood work, I have elevated white blood cells, elevated RDW and platlets, elevated neutrophils, moncytes, Eos, below normal mcv, mch, mchc, hematocrit, hemoglobin, 0 platelet antibodies .. Pretty much all CBC is off in one way or another. Went for more blood work 30 days later same thing. Today they sent me to do a C-reactive, ESR, and blood smear.. When I was in getting labs. on this tue.. I asked if the doc could do a ua for possiable URI, i had all classic symtoms, the nurse asked the do they said I had to make a seperate apt for that. Well seeing I had been doign that since Thurs.. I didnt want to wait until the 16th when they could get me in, who wants to be miserable a month. I went to a walk in clinic to be tested for UTI.. They did UA no bacteria just protiein and stuff in the urine. They gave me bactrim twice a day for 3 days, to see if it helped at all. And when the doctor sent me for the new blood work today i forgot to mention I was taking bactrim from the other doctor. The only meds I am currently taking... I am wondering will it affect any of these blood tests? Not even sure what they might be looking for at this time. or what any of these values my mean..
