Abstract
Synthetic stool, adaptable to use as a control standard in the diagnostic detection of substances contained in stools and for demonstration purposes, said stool comprising a matrix of a member selected from the group consisting of oxygen-containing organic polymers which are difficultly soluble in water and oxygen-containing inorganic solids difficultly soluble in water, a non-bleeding coloring agent adherent to said matrix and simulating the color of a stool, and a liquid selected from the group consisting of water and lubricants.
Claims2
A synthetic human stool, spreadable on a substrate and adaptable to use as a control standard in the diagnostic detection of occult blood in the stool, said synthetic stool consisting essentially of a matrix of a member selected from the group consisting of oxygen-containing organic polymers which are difficultly soluble in water and oxygen-containing inorganic solids difficultly soluble in water, a non-bleeding coloring agent adherent to said matrix and simulating the color of a human stool, a liquid selected from the group consisting of water and lubricants, and a predetermined amount of hemolyzed human blood, said coloring agent on treatment with hydrogen peroxide showing no change in color or no change in color interfering with such a diagnostic detection of occult blood.
