| tetrazolium | Any of a group of organic salts having the general structure which on reduction (cleaving the 2,3 bond) yields a coloured insoluble formazan; used as a reagent in oxidative enzyme histochemistry. Nitroblue tetrazolium (NBT), a pale yellow dye that is converted on reduction to coloured formazans in the histochemical demonstration of dehydrogenases; used in haematology for staining of neutrophils to help indicate the presence of bacterial infections.

| tetrazolium salts | <chemical> Quaternary salts derived from tetrazoles. They are used in tests to distinguish between reducing sugars and simple aldehydes, for detection of dehydrogenase in tissues, cells, and bacteria, for determination of corticosteroids, and in colour photography. Pharmacological action: indicators and reagents. (12 Dec 1998) |
| amine tetrazolium reductase | <enzyme> Tetrazolium salts as hydrogen acceptors Registry number: EC 1.4.- Synonym: tryptamine dehydrogenase, monoamine tetrazolium reductase, monoamine dehydrogenase (26 Jun 1999) |

| NADH tetrazolium reductase | <enzyme> Catalyses the reduction of tetrazolium compounds in the presence of NADH. Registry number: EC 1.6.- (12 Dec 1998) |
| NADPH-tetrazolium reductase | <enzyme> Reported to possess activity identical with NADPH cytochrome c reductase EC 1.6.2.4 Registry number: EC 1.6.2.- Synonym: NADPH-neotetrazolium reductase, NADPH-nbt reductase (26 Jun 1999) |
| nitroblue tetrazolium | <chemical> 3,3'-(3,3'-dimethoxy-4,4'-biphenylene)bis (2-(p-nitrophenyl)-5-phenyl-2h-tetrazolium. Colourless to yellow dye that is reducible to blue or black formazan crystals by certain cells; formerly used to distinguish between nonbacterial and bacterial diseases, the latter causing neutrophils to reduce the dye; used to confirm diagnosis of chronic granulomatous disease. Pharmacological action: indicators and reagents. Chemical name: 2H-Tetrazolium, 3,3'-(3,3'-dimethoxy(1,1'-biphenyl)-4,4'-diyl)bis(2-(4-nitrophenyl)-5-phenyl-, dichloride (12 Dec 1998) |
| nitroblue tetrazolium reduction | <chemical> Nitroblue tetrazolium, a yellow dye, is taken up by phagocytosing neutrophils and reduced to insoluble formazan, which is deep blue, if the metabolic burst is normal. Reduction does not take place in chronic granulomatous disease. (18 Nov 1997) |
| nitroblue tetrazolium test | A test to detect the phagocytic ability of polymorphonuclear leukocytes by measuring the capacity of the oxygen-dependent leukocytic bactericidal system. (05 Mar 2000) |
