Fecal occult blood test

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

• Definition: Collection of a stool sample to detect non-visible blood using a faecal immunochemical test (FIT).
• Fasting: No fasting is required. You can eat and drink water normally. As this is an immunochemical test, no special diet is needed.
• Medication: Consult your doctor if you take anti-inflammatory drugs (aspirin, ibuprofen, naproxen) or anticoagulants. Do not stop any treatment without medical advice.
• Clothing and Accessories: There are no special requirements.
• Specific Requirements:
  • Use the collection tube you are given and follow the kit instructions. A sample from a single bowel movement is usually enough; if your centre asks for more, follow their instructions.
  • Using the stick in the tube, take the sample from several areas of the stool, close the tube tightly and write down the date.
  • The stool must not touch urine or the toilet water.
  • Do not do the test during your period or if you have bleeding haemorrhoids.
  • Hand in the sample as soon as possible; if there will be a delay, keep it in the fridge.
• Discomfort or pain after the test: None. It is a non-invasive test that only requires collecting a stool sample naturally.
