Your doctor will ask you to provide a clean-catch urine sample. You will be given a sterile container and instructions on how to clean the area around the urethra. Do not touch inside the container.
The urine sample will be sent to the laboratory where a urine culture is performed. The urine culture will determine if there are bacteria in your urine.
The diagnosis of asymptomatic bacteriuria requires:
A urine culture that is positive for a large number of bacteria
You do not have symptoms of a urinary tract infection.
