iFOBT (Fecal Occult Blood)

The iFOBT (immunochemical Faecal Occult Blood Test) is a non-invasive screening tool that checks for hidden blood in the stool. For older adults, this test may support early awareness of gastrointestinal changes. A positive result does not necessarily indicate a serious condition, but should be discussed with your healthcare provider.

What It Measures

This test specifically detects human haemoglobin in a stool sample, indicating the presence of blood that is not visible to the naked eye. It uses antibodies targeted at human haemoglobin, making it more specific than older guaiac-based tests.

Why It Matters

Early detection of hidden blood in the stool can lead to the timely identification of colorectal polyps, inflammatory bowel disease, or colorectal cancer. When detected early, many colorectal conditions are highly treatable. Regular screening is an important part of preventive healthcare.

When to Test

iFOBT can be recommended as part of colorectal cancer screening. It may also be recommended if there is a family history of colorectal cancer or if symptoms such as changes in bowel habits, unexplained weight loss, or abdominal discomfort are present.

Symptoms

Low Levels

A negative result suggests that no hidden blood was detected in the stool sample at the time of testing. This is a reassuring finding, though it does not entirely rule out colorectal conditions. Regular repeat screening as recommended by your healthcare professional remains important.

High Levels

A positive result may indicate the presence of blood in the stool, which can be associated with colorectal polyps, inflammatory bowel disease, haemorrhoids, or colorectal cancer. A positive result does not confirm a diagnosis but indicates that further investigation, typically a colonoscopy, is recommended. Consult a healthcare professional for interpretation of results.

Lifestyle Tips

Maintaining a diet rich in fibre, staying physically active, limiting processed and red meat consumption, avoiding excessive alcohol, and not smoking are all associated with reduced colorectal cancer risk. Adhering to recommended screening intervals is one of the most effective preventive measures.

Frequently Asked Questions

What does a positive iFOBT result mean?
A positive result means that hidden blood was detected in your stool sample. This does not necessarily mean you have cancer. Blood in the stool can result from polyps, haemorrhoids, inflammation, or other conditions. Your healthcare professional will typically recommend a colonoscopy for further evaluation.
Do I need to follow a special diet before the test?
Unlike older guaiac-based tests, the iFOBT does not typically require dietary restrictions because it specifically detects human haemoglobin. However, follow any instructions provided by your healthcare professional or the testing kit.
How often should I have an iFOBT?
Screening frequency depends on your age, risk factors, and prior results. Many guidelines recommend annual or biennial iFOBT for adults over 50. Your healthcare professional will advise on the appropriate interval for your situation.
