A test sheet for the determination of the presence of a substance having peroxidase-like activity in a throw-in-the-bowl fecal occult blood test, includes a specimen test area and a positive control area. The test area has deposited thereon a test ink having at least one oxygen donor reagent and a chromogen reagent capable of being oxidized by the oxygen donor in the presence of blood or a substance having peroxidase-like activity, to provide a visually observable change of color. The test ink also includes a water soluble polymer for immobilizing the chromogen and oxygen donor. The positive control area has deposited thereon the test ink and a substance having the peroxidase-like activity.
