Why is it i have white cells elevated in my urine yet when they do the urine culture nothing grows?

Other causes: Chlamydia, mycoplasma, and some possibly-immune bladder conditions can do this, and since you are a woman, there are always white cells in the vagina and doing the "clean catch" maneuver you're supposed to do for the urine is difficult or impossible. Don't forget TB or one of the obscure kidney diseases may also be considerations. Good luck, and correlate with your clinical findings.
