ABSTRACT:
A diagnostic agent for the detection of ketones in fluids consisting of an absorbent carrier impregnated with sodium nitroferricyanide, a water-soluble lower amino acid, an alkaline buffer substance, and at least one organic acid, said organic acid serving to form a stabilizing environment around the sodium nitroferricyanide. The improved diagnostic agent may be produced by impregnating the carrier in a first step with an aqueous solution of the buffer substance and the amino acid, in a second step with a solution of an organic acid in an organic solvent and in a third step with a solution of sodium nitroferricyanide and a water-soluble organic acid in an organic solvent.
