Stool Occult Blood
The Stool Occult Blood test detects hidden blood in stool and helps screen for digestive tract disorders and colorectal cancer.About Test
The Stool Occult Blood Test is used to detect hidden (occult) blood in the stool that is not visible to the naked eye.
The presence of blood in stool may indicate bleeding in the digestive tract, which can be caused by conditions such as ulcers, haemorrhoids, polyps, inflammation, or colorectal cancer.
This test is widely used as a screening tool for colorectal cancer and helps detect issues at an early stage when treatment is more effective.
Since the bleeding may be intermittent, doctors may sometimes recommend repeating the test for accurate evaluation.
