Abstract
A test agent for the detection of coupling compounds in liquids is described, which essentially consists of an adsorbent matrix containing a diazonium salt as the reagent and a phosphonium salt to stabilize said test agent. Furthermore there is described a process for the preparation of said test agent.

A stabilized rapid diagnostic agent for the detection of coupling compounds in biologic fluids consisting essentially of an adsorbent carrier matrix comprising fleeces, paper, asbestos or polymer films, said matrix being impregnated with a diazonium salt as reagent for said coupling compounds and a phosphonium salt as stabilizer for said rapid diagnostic agent wherein said phosphonium salt is present in an effective amount to stabilize said rapid diagnostic agent.
A process for the preparation of a stabilized rapid diagnostic agent for the detection of coupling compounds in biologic fluids which consists essentially of impregnating an adsorbent carrier matrix comprising fleeces, paper, asbestos or polymer films with a diazonium salt as reagent for said coupling compounds and thereafter impregnating said matrix with an effective amount of a phosphonium salt to stabilize said rapid diagnostic agent.
