Stool - Occult Blood

An FOBT is often done to screen for early colon or rectal cancer. Hidden blood in your stool can be a sign of these diseases.

No fasting is required for an FOBT. However, you should follow your doctor's instructions regarding diet and medication restrictions.

A positive FOBT result means that blood was found in your stool. While this can be a sign of cancer, other conditions can also cause blood in the stool, such as polyps, ulcers, or hemorrhoids.

The frequency of testing depends on your age, health, and family history. Generally, if you're 50 or older and at average risk for colorectal cancer, your doctor may recommend you have an FOBT annually.

A normal result is negative, meaning no blood was found in your stool during the testing period.

Avoid certain foods and medications for several days before the test as they can interfere with the results.

Diet, medications, and the presence of other gastrointestinal conditions can affect the result.

A positive result indicates the presence of blood in the stool. It does not necessarily mean you have cancer but further testing is needed to determine the cause.

Yes, FOBT kits can be used at home. You'll need to collect samples from multiple bowel movements and return them to your doctor or a lab.

The risks associated with an FOBT are minimal. There might be a false-positive or false-negative result.

A negative result means no blood was found in your stool. A positive result indicates blood was found, requiring further investigation.

Yes, certain medications, like aspirin or other NSAIDs, can cause gastrointestinal bleeding and lead to a positive result.

Yes, certain foods can cause a false-positive result. It's recommended to avoid red meat, certain vegetables, and vitamin C supplements before the test.

No, an FOBT can't diagnose cancer. It can detect blood in the stool, which could be a sign of cancer or other conditions. Further investigation is needed to confirm a diagnosis.

Follow the dietary and medication guidelines your doctor provides. These are designed to minimize factors that could produce a false positive.

While the FOBT is a good screening tool for blood in the stool, it's not perfect. False positives and negatives can occur.

Yes, bleeding from hemorrhoids or menstruation can result in a positive test.

If you have a positive FOBT, you should consult a gastroenterologist for further evaluation.

Usually, a colonoscopy is recommended after a positive FOBT to identify the source of the bleeding.

Understanding the value of the FOBT can help you catch health issues in their early stages, where treatment can be most effective. If you've been recommended to take an FOBT, don't hesitate. Your proactive approach can make all the difference.
