Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like frequent urination, pain or burning during urination, cloudy or strong-smelling urine, or fever. It helps determine if a UTI is present and caused by *E. coli* bacteria.

What to Expect Before the Test

No special preparation is needed. You’ll likely provide a urine sample in a clean container, often collected at a clinic or lab. If you’re pregnant or have kidney concerns, let your provider know before testing.

What the Test Results Mean

A positive result means *E. coli* DNA was found in your urine, strongly suggesting a UTI. A negative result means no *E. coli* DNA was detected, but other causes of symptoms (like infection by different bacteria or irritation) could still be present.

What Happens Next

If the test is positive, your provider may prescribe antibiotics to treat the infection. Follow-up tests or imaging (like a CT scan) might be needed if symptoms persist or if other complications are suspected.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
