<p>An electrochemical diagnostic device and a method for conducting diagnostic tests in clinical, veterinary, industrial and laboratory applications comprises a fibrous matrix feeder strip (2, 13) contacting at one end a sample holder (1) and incorporating optional filter elements (3-5), the other end being contactable with working (16), reference (19) and auxiliary electrodes (10) and reagent carriers (12, 15). Sample is transferred by capillary action from the sample holder along the feeder strip to allow a reaction between the target analyte and reagents to take place and also allowing electrical conductivity between the electrodes. The reaction end product is measured by amperometric, coulometric or other voltammetric means.</p> |
