Fecal Occult Blood Test - what is it and how the test is done
- Anal fissure
- Polyps (cancerous and noncancerous)
- Ulcerative colitis
- Crohn’s Disease
FOBT checks the stool sample for occult bleeding (bleeding from gastrointestinal parts that end up in the stool). Bleeding can be caused by haemorrhoids, anal fissures, polyps, ulcerative colitis, Crohn's Disease, and colorectal cancer.
It is intensely used for diagnosing colorectal cancer before the appearance of symptoms. It is also used to help find the cause of anaemia. It can distinguish between irritable bowel syndrome (IBS), which usually doesn't cause bleeding, and inflammatory bowel disease (IBD), which is likely to cause bleeding.
It is recommended to undergo FOBT if suspected of bleeding. The screening tests can start at age 45 or 50 if a person has an average risk of developing colorectal cancer.
The provider will provide you with the kit for sample collection. The instructions for the equipment must be followed. The sample, once collected, must be stored in a prelabelled container with patient details, sealed and sent to the laboratory. The test can be reordered if the sample is inconclusive.
Avoid Vit C supplements, red meat (beef, lamb, pork), NSAIDs (Aspirin, Ibuprofen) drugs, and spicy food the day before the test, as these can alter results.
