View in Spanish: Análisis inmunológico de sangre oculta en la materia fecal

Immunologic fecal occult blood test (IH-myoo-noh-LAH-jik FEE-kul uh-KULT)
A test to check for blood in the stool. A brush is used to collect water drops from around the surface of a stool while it is still in the toilet bowl. The samples are then sent to a laboratory, where they are checked for a human blood protein. Blood in the stool may be a sign of colorectal cancer. Also called iFOBT, immunoassay fecal occult blood test, and immunochemical fecal occult blood test.
