Stool Analysis

Fecal Analysis

How To Prepare

Many medicines can change the results of this test. You will need to avoid certain medications, such as antacids, antidiarrheal medications, antiparasite medications, antibiotics, enemas, and laxatives for 1 to 2 weeks before you have the test. Be sure to tell your doctor about all the non-prescription and prescription medicines you take.

Be sure to tell your doctor if you have:

• Recently had an X-ray test using barium contrast material, such as a barium enema or upper gastrointestinal series (barium swallow). Barium can interfere with test results.
• Travelled in recent weeks or months, especially if you have travelled outside the country. Parasites, fungi, viruses, or bacteria from other countries may affect the test.

If your stool is being tested for blood, you will need to follow a special diet for 2 days before the stool collection period begins. Your doctor will give you a list of recommended foods.

• Do not eat red meat, turnips, cauliflower, broccoli, bananas, cantaloupe, beets, or parsnips.
• Do not drink alcohol, including wine and beer.
• Do not take ASA, ibuprofen, or vitamin C.
