Provided is a method for the detection of a protein, such as Hb, in a test sample, the method comprising the steps of: (i) exposing the sample to a surface having a binding moiety and permitting the binding moiety to specifically immobilise the protein in the sample; (ii) permitting the immobilised protein to catalyse a reaction of a first reagent with a second reagent; (iii) detecting, such as electrochemically detecting, the reaction of the first reagent with the second reagent. The binding moiety may be provided on the surface of an electrode. |
