What diseases can stool occult blood detect?

Fecal occult blood test is a test used to detect gastrointestinal bleeding. It can be used to diagnose a variety of diseases, including peptic ulcer, digestive tract polyps and digestive tract tumors.

1. Peptic ulcer,

such as gastric ulcer and duodenal ulcer, can lead to erosion and bleeding of gastrointestinal mucosa. When bleeding is small, it may not be detected after mixing with feces, but it is helpful to diagnose by fecal occult blood test.

2. Digestive tract

polyps, such as gastric polyps and colon polyps, may lead to damage to gastrointestinal mucosa and bleeding, thus making fecal occult blood test positive.

3. Digestive tract tumors, such

as gastric cancer, rectal cancer and colon cancer, are one of the common causes of gastrointestinal bleeding. They can also be detected by fecal occult blood test.
