My urine culture report shows me e-coli organisum three times from three months .i had several antibiotics. should they keep testing for cure if i have no symptoms ?

Urine Culture: Depending on your age you may not need to keep looking for a cure if no symptoms are present. A contaminated urine culture could happen if a "clean catch" is not obtained. Also a urine culture should show anti-biotic sensitivies so you and your doctor could better target your therapy.

Bactiuria vs UTI: E coli is the most common cause of UTI but also the most common contaminant in urine cultures. The doctors should also do a urinalysis to look for wbcs & epithelial cells to differentiate. The # of organisms also needs to be quantitated. We used to think asymptomatic bactiuria was unimportant but now we know it can lead to issues esp in pregnant/elderly or tell us of urinary tract abnormalities.
