Tests and diagnosisBy Mayo Clinic staff
To diagnose antibiotic-associated diarrhea, your doctor may:
- Ask questions about your health history. Expect your doctor to ask about your medical history, including whether you've had recent hospitalizations or antibiotic treatments.
- Analyze a stool sample. If your symptoms are severe, you may be asked to provide samples of your stool. Stool samples can be tested in a laboratory to determine which bacteria are causing your antibiotic-associated diarrhea. This can help your doctor select the proper treatment.
