Abstract
Fecal occult blood tests of enhanced sensitivity and specificity are provided by employing (1) a developer composition comprising a solution of a hydroperoxide in a solvent comprising at least about 50% by volume of a solvent for iron protoporphyrins such as dimethyl sulfoxide and/or (2) a solid test matrix comprising a solid support impregnated with a leuco dye and a hemoprotein solubilizing agent. Test results may be further improved by incorporating plant peroxidase inhibitors, iron/copper chelating agents and buffers in the developer and/or test matrix.
