What is the Guaiac-Based Fecal Occult Blood Test (gFOBT)?
The *Guaiac-Based Fecal Occult Blood Test* (gFOBT) is a non-invasive screening tool used to detect hidden (occult) blood in the stool. This test is particularly important in the context of *colorectal cancer* as it can help identify early signs of cancer or precancerous polyps, which can bleed into the digestive tract.
