Tests and diagnosis
By Mayo Clinic staffTests and procedures used to determine what's causing your diarrhea may include:
- Physical exam. Your doctor may examine your abdomen to determine the location of any abdominal pain. Your doctor may also listen to your abdomen with a stethoscope.
- Review of your medications. Your doctor may ask about any medications you're taking, including over-the-counter drugs. Also, tell your doctor about any supplements you take.
- Blood test. A complete blood count test may help determine what's causing your diarrhea.
- Stool test. Your doctor may recommend a stool test to determine whether a bacterium or parasite is causing your diarrhea.
