Fecal occult blood test

This test aims to detect small amounts of blood in stool that are not visible to the naked eye. It is essential to follow the collection instructions to avoid false results.

• Definition: Collection of stool samples to detect non-visible blood using an immunochemical test (FIT).
• Fasting: No fasting required. You can eat and drink normally. As this is an immunochemical test, no special diet is needed.
• Medication: Consult your doctor if you take anti-inflammatories (aspirin, ibuprofen, naproxen) or iron or vitamin C supplements, as they may alter results. Do not stop any treatment without medical advice.
• Clothing and Accessories: No special requirements.
• Specific Requirements: Collect a sample from three different bowel movements, usually on three consecutive days. Use a different sterile container for each day and note the date. Stool must not come into contact with urine or toilet water. Do not collect during menstruation or with bleeding hemorrhoids.
• Expected discomfort or pain from the test: None. This is a non-invasive test that only requires collecting stool samples naturally.
