My WBC is 17.5. I also show WBC's in my urine, 0-3 RBC's and no or low colony count. Is this a low grade UTI or something worse? According to my lab work, I'm not showing any signs of anemia. My platelets are fine and so is my thyroid. I don't remember if I felt sick or had a cold when I had my labs drawn the first time which was 13.4. Two to three weeks later i went to the doc again to discuss the lab results and he wanted to retest my WBC and my urinalysis. My urinalysis was a little better but my WBC's went up to 17.5. I have IBS, allergies, sinus problems, PCOS, diabetes/insulin resistance, elevated DHEAS (in the past) and, oh yes, stress like you wouldn't believe. My doc is wanting my to go to a hematologist and I'm nervous. My WBC's have been elevated for the past 13 years. Has anyone else went to a hematologist over this?
