1. Method for determining the presence of an analyte in a sample comprising:

  • a) providing a test device incorporating a lateral flow test strip comprising a dry matrix material capable of transporting a liquid therealong by capillarity and having at least a start zone for receiving said sample and a reaction zone having at least one kind of enzyme immobilised therein;

    b) contacting the start zone with said sample thereby causing a liquid phase to move through said test strip;

    c) determining a detectable signal at the reaction zone directly or indirectly caused by covalent modification of the analyte by the enzymes at the reaction zone
