Abstract
A dry strip element for use in an electrochemical assay for determining theophylline in a sample, the test element carrying a working electrode and a reference electrode and separately carrying at the working electrode an alkaline phosphatase and an electroinactive phosphate ester which is a substrate for the alkaline phosphatase and from which an electroactive compound can be released by catalytic activity of the alkaline phosphatase.
