Stool for Occult Blood

The Stool for Occult Blood test checks for hidden (occult) blood in the stool, which may not be visible to the naked eye. This test is used to detect gastrointestinal bleeding that could be caused by conditions like ulcers, polyps, hemorrhoids, or even colorectal cancer. It is commonly performed as part of routine screening or when a patient presents with symptoms such as abdominal pain, unexplained weight loss, or changes in bowel movements.

Why consider this test?

Occult blood in the stool is often an early indicator of gastrointestinal issues that may not have obvious symptoms. The test helps detect bleeding from sources such as ulcers, diverticulosis, or colorectal cancer, even before visible signs like blood in the stool appear. Early detection allows for timely treatment and intervention.

Who should get this test done?

• Individuals over the age of 50 who are undergoing routine colorectal cancer screening.
• People with a family history of colorectal cancer or other gastrointestinal disorders that increase the risk of occult bleeding.
• Individuals with unexplained gastrointestinal symptoms, such as abdominal pain, bloating, or changes in bowel habits.
• Patients with anemia or low iron levels, which may be caused by chronic blood loss in the gastrointestinal tract.

More Information

The stool for occult blood test is typically done using a small stool sample collected at home. Multiple tests may be required for a conclusive result, as certain foods or medications can interfere with the test. Positive results often lead to further investigations, such as colonoscopy, to identify the source of bleeding.
