Hello, what does it mean in a urine exam when the WBC esterase is +3. WBC 11-30, , Epethelial cells (non renal) >10, bacteria cells many abnormal?

Not a mystery. Hi. You have a urinary tract infection (UTI), probably just a bladder infection, but possibly an upper urinary tract infection (much sicker). Whoever ordered your UA and microscopic will assess your status and treatment needs based on more information than is available to us. Get well soon!
