Hi, I'm Doctor Robert, a Medical Internist (MD) who deals with diseases of all organ systems. All my education has been completed in the US. Trace amounts of leukocyte esterase which is produced by White Blood Cell (WBC) in the urine. That they are there indicates the possibility of an infection. Normal urine has NO WBC's, so if they're there, they're there for a reason; to fight bacteria.
