In veterinary medicine, oxidase discs are small, sterile filter paper discs impregnated with a specialized chemical reagent used in microbiological testing to rapidly determine whether a bacterial isolate synthesizes the enzyme cytochrome c oxidase.

Specs & features.
These diagnostic discs are constructed from high-quality, absorbent filter paper precut into small circles. They come pre-treated with an analytical redox indicator reagent—most commonly Kovacs reagent (N,N,N',N'-tetramethyl-1,4-phenylenediamine) or N,N-dimethyl-p-phenylenediamine oxalate combined with α-naphthol. To perform the test, a clinician uses a plastic loop or sterile wooden stick to pick up an isolated bacterial colony from an agar plate and rubs it directly onto the disc.

- Ultra-Fast Visual Diagnostics: Delivers a clear, unmistakable color change from colorless to deep purple-blue within 5 to 30 seconds for an immediate presumptive diagnosis.
- Pre-Impregnated Convenience: Eliminates the historical need for veterinary technicians to compound fresh, highly unstable liquid oxidase reagents daily.
- Auto-Oxidation Protection: Formulated with added stabilizers like ascorbic acid, which prevents the discs from reacting prematurely with ambient atmospheric oxygen while in storage.
