Medical Definition of Ascorbate-cyanide test
1. A test for glucose-6-phosphate-deficient red blood cells; blood is incubated with sodium cyanide and ascorbate; the hydrogen peroxide generated is free to oxidise haemoglobin to methemoglobin, since cyanide inhibits catalase; a brown colour is produced more rapidly in glucose 6-phosphate-deficient cells.
