Why This Test Is Done

Your healthcare provider may order this test if you’re taking levofloxacin to treat or prevent certain bacterial infections. It helps ensure the medication is working as intended and is present in your system.

How the Test Works

A urine sample is tested using a dipstick or strip that detects levofloxacin. The strip changes color if the antibiotic is present, which is then interpreted by a healthcare professional.

Sample Collection

You’ll likely collect a midstream clean-catch urine sample. Follow your provider’s instructions carefully to ensure accurate results.

What to Expect

The test is quick and painless. You may see a color change on the strip, but results are interpreted by a lab technician or doctor.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
