The test is based on the interpretation of the discoloration of the feces solution after the addition of the reagents, which allows the detection of occult blood in stool specimens.
- The presence of blood hemoglobin (Hb) may convert H2 and O2 into H2O and O2; at the same time, the O2 may oxidize the indicator (O-Tolidine) and generate a green-colored solution.
