  • Interference-resistant composition, device and method for determining a peroxidatively active substance in a test sample
    Patent number: 4310626
    Abstract: A composition, test device and method of use in determining the presence of a peroxidatively active component in a test sample are disclosed. The composition comprises an organic peroxide, an indicator capable of providing a detectable response in the presence of the peroxide and a peroxidatively active substance, and a complex of Co(III). Inclusion of the Co(III) complex renders the composition resistant to the adverse effects of ascorbate, which might be present in the test sample. The test device comprises a carrier matrix incorporated with the composition. The method comprises contacting the test sample with the device and observing a detectable response therein.
