What is a Fecal Occult Blood Test?

A Fecal Occult Blood Test (FOBT) is a non-invasive medical test used to check for hidden (occult) blood in the stool, which is not visible to the naked eye. This test is important because the presence of blood in the stool can be an early sign of colorectal cancer or other conditions such as polyps, haemorrhoids, ulcers, or gastrointestinal bleeding. Detecting blood early can lead to early diagnosis and more effective treatment of these conditions.

How Does the Test Work?

The FOBT works by detecting haemoglobin, a protein contained in red blood cells, that may be present in the stool. There are a couple of methods used to perform the test: the guaiac-based fecal occult blood test (gFOBT) and the faecal immunochemical test (FIT). The gFOBT uses a chemical reaction to detect blood, while the FIT uses antibodies that specifically recognise human haemoglobin. The FIT test is often preferred because it is more specific and does not require dietary restrictions before the test.

Why is the Test Important?

Early detection of colorectal cancer significantly improves treatment outcomes. Regular screening with FOBTs can detect cancer at an early stage when treatment is more likely to be successful. In the UK, bowel cancer is a major health concern, and early detection through screening programmes, including the use of FOBTs, has been shown to reduce mortality rates. Besides cancer, the test can help identify other gastrointestinal issues that may need medical attention.

Who Should Take the Test?

In the UK, individuals aged 60 to 74 are invited to complete a FOBT every two years as part of the NHS Bowel Cancer Screening Programme. People outside this age range or those with higher risk factors, such as a family history of bowel cancer, may also need to discuss screening options with their GP. It is important to participate in regular screening if you fall within the recommended age range, as many bowel cancers can be detected early through these programmes.

How to Perform the Test?

Performing an FOBT is simple and can be done in the privacy of your home. The NHS usually provides a test kit by mail, which includes instructions on how to collect stool samples using provided sticks or brushes. Once samples are collected, they are sent back to the lab using a prepaid envelope. It is essential to follow the instructions carefully to ensure accurate results. If the test detects blood, further diagnostic procedures such as colonoscopy may be recommended to determine the cause of the bleeding.

Conclusion

The Fecal Occult Blood Test is a crucial tool in the detection of bowel cancer and other gastrointestinal problems. It is a simple, cost-effective, and efficient means of catching potential health issues before they become severe. Participating in regular screening and staying informed about the test can significantly contribute to early diagnosis and improved health outcomes.

What is a Fecal Occult Blood Test?

A Fecal Occult Blood Test (FOBT) checks for hidden blood in your poo. You can't see this blood with your eyes. This test is important because finding blood early can help doctors find and treat problems like bowel cancer or other issues like piles, ulcers, or bleeding inside your tummy. Early detection means better treatment.

How Does the Test Work?

The test looks for a protein called haemoglobin in your poo. This protein is in red blood cells. There are two types of FOBT: the gFOBT and the FIT. The gFOBT uses a chemical to find blood, and the FIT uses a special tool to find human blood. People like the FIT because it is more accurate and you don’t have to change what you eat before the test.

Why is the Test Important?

Finding bowel cancer early makes treatment work better. Regular FOBT tests can catch cancer early when it can be treated more easily. In the UK, bowel cancer is a big health issue. Using FOBT tests can save lives because it helps find cancer early. It can also find other tummy problems that need a doctor’s help.

Who Should Take the Test?

In the UK, people aged 60 to 74 get a free FOBT kit every two years. This is part of a health check called the NHS Bowel Cancer Screening Programme. If you are younger or have family members with bowel cancer, talk to your doctor. It’s important to take the test if you are in the age group because it helps find cancer early.

How to Perform the Test?

You can do the FOBT at home. The NHS sends you a kit with instructions. You use the kit to collect a small amount of your poo. You then send it back in a prepaid envelope. It’s very important to follow the instructions correctly. If the test finds blood, you might need more tests like a camera test (colonoscopy) to find out why there is bleeding.

Conclusion

The Fecal Occult Blood Test is important for finding bowel cancer and other tummy issues. It’s a simple and cheap way to catch problems early. Doing regular tests and knowing about them can help find and treat problems early, making you healthier.
