Most of the time, your urine is sterile. This means there is no bacteria growing. On the other hand, if you have symptoms of a bladder or kidney infection, bacteria will be present and growing in your urine.
Sometimes, your health care provider may check your urine for bacteria, even when you do not have any symptoms. If enough bacteria are found in your urine, you have asymptomatic bacteriuria.
Screening - asymptomatic bacteria
Asymptomatic bacteriuria occurs in a small number of healthy people. It affects women more often than men. The reasons for the lack of symptoms are not well understood.

There are no symptoms of this problem.
If you have these symptoms, you may have a urinary tract infection, but you do not have asymptomatic bacteriuria.
Most people who have bacteria growing in their urine, but no symptoms, do not need treatment. This is because the bacteria are not causing any harm. In fact, treating most people with this problem may make it harder to treat infections in the future.
However, for some people getting a urinary tract infection is more likely or may cause more severe problems. As a result, treatment with antibiotics may be needed if:
Without symptoms being present, even people who are older adults, have diabetes, or have a catheter in place do not need treatment.
