Process for deteccao of activity of peroxidase.The material in the form of a bar indicator to be used in the deteccao occult blood test reagent system and for the presence of activity of peroxidase deteccao

摘要

There is disclosed a method for the detection of peroxidase activity, which method comprises the steps of: a) collecting a specimen which is to be analysed for the presence of peroxidase activity; b) contacting the specimen, with a composition prepared by admixing (i) a tablet comprising from 3% to 40% of an indicator material and from 60% to 97% of an excipient; and (ii) an aqueous-organic reagent solution containing an organic solvent, an oxidizing agent being capable of oxidizing said indicator material in the presence of peroxidase activity, a buffer, and water; and c) detecting the presence or absence of peroxidase activity. A test reagent system and a tablet for use in the method are also disclosed.
