Abstract
A test composition, device and method for determining a peroxidatively active substance in a test sample, as well as a method for preparing the device, are disclosed. The composition comprises an organic hydroperoxide and an indicator capable of providing a detectable response in the presence of the organic hydroperoxide and peroxidatively active substance, wherein the organic hydroperoxide is a substituted cumene hydroperoxide having the formula: ##STR1## in which any one of the X substituents is lower alkyl of from 1 to 6 carbon atoms, Cl, Br, I, NO.sub.2 or carboxyl; or any two of the X substituents, same or different, are lower alkyl of from 1 to 6 carbon atoms, Cl, Br, I, NO.sub.2 or carboxyl. The device comprises a carrier matrix incorporated with the composition, and the method comprises contacting a test sample with the device and observing a detectable response in the device. A method for preparing the device comprises preparing a solution of the composition, wetting the carrier matrix therewith and drying the wetted matrix.
