The guaiac fecal occult blood test (gFOBT) is a noninvasive colorectal cancer (CRC) screening test performed on normal-appearing stool to detect occult blood originating from the lower gastrointestinal tract. Such bleeding may represent a cancer or adenomatous polyp, and may be the only sign of smoldering disease.

Clinical Information (ข้อมูลทางคลินิก):
A variety of parasites can cause infections of the digestive system (gastrointestinal (GI) infections). An ova and parasite (O&P) exam is a microscopic evaluation of a stool sample that is used to look for parasites that may infect the lower digestive tract, causing symptoms such as diarrhea. The parasites and their eggs (ova) are shed from the lower digestive tract into the stool.
