Tests and diagnosis discussion for Diarrhea:

Diagnostic tests to find the cause of diarrhea include the following:

  • Medical history and physical examination. The doctor will need to know about your eating habits and medication use and will examine you for signs of illness.

  • Stool culture. Lab technicians analyze a sample of stool to check for bacteria, parasites, or other signs of disease or infection.

  • Blood tests. Blood tests can be helpful in ruling out certain diseases.

  • Fasting tests. To find out if a food intolerance or allergy is causing the diarrhea, the doctor may ask you to avoid lactose (found in milk products), carbohydrates, wheat, or other foods to see whether the diarrhea responds to a change in diet.

  • Sigmoidoscopy. For this test, the doctor uses a special instrument to look at the inside of the rectum and lower part of the colon.

  • Colonoscopy. This test is similar to sigmoidoscopy, but the doctor looks at the entire colon.
