The presence of blood anywhere, especially in any of your body fluids or secretions, could be an alarming sign. It indicates that something serious is going on inside your body, whether you have any other symptoms or not.
It is always important and the foremost priority of a person to get themselves checked if they ever notice bloody discharge anywhere in their body. In most people, it is common to come across blood on their stools.
There are several reasons for the presence of blood in the stool, and they could be both serious and non-serious, such as:
- Anal fissure
- Polyps (cancerous and noncancerous)
- Ulcerative colitis
- Crohn’s Disease
However, it is always important to rule out the possibility of a severe underlying issue that could endanger your body in the long run.
A faecal occult blood test is ordered for this purpose. It involves the collection of stool samples at different times of the day since, in many people, the blood may not always accompany the stool whenever and wherever. Once sent to the lab, these stool samples are analysed for the presence of blood and the underlying causes that might be causing it to appear.

FAQs on Fecal Occult Blood Test
What is a Fecal Occult Blood Test?
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.
Why is it needed?
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.
How to prepare for it, and what to expect from the results?
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.
