Have uti symptoms had test shows white cells in urine and blood yet the urine culture shows no uti have back pain too what could be wrong?

Probably still UTI: Hi Jessi, It certainly sounds as if you have a UTI. A urine culture can be falsely negative, as can any lab test. Were you taking antibiotics when the culture was done, causing a negative culture? Other possibilities are urinary tract stones and bladder tumor. I suggest rechecking the urinalysis and culture, and then see your doctor or a urologist to help you look into it further. Good luck
