The present invention involves an improvement tonan assay for the activity of a metal chelate, such asncopper II/creatinine, which activity is related to thenconcentration of the analyte in a fluid test sample.nIn carrying out the assay, there is combined the fluidntest sample, the metal chelate or precursors thereof,na hydroperoxide, an oxidizable indicator and a pyrazolenderivative which inhibits the ability of hemoglobinnto oxidize the oxidizable dye. |
