A lancet (10) for drawing blood or other bodily fluid is provided with a region (17) where a chemical reagent resides that reacts with at least one constituent of the bodily fluid to ascertain information about the bodily fluid. The lancet (10) has a body (11) and a head (12) provided with a sharp tip (14) for penetrating the skin. The tip (14) is provided with at least one channel or groove (16) in fluid communication with the area where the chemical reagent is positioned. An electroconductive ink is positioned on the lancet to form electrical contacts (19, 20), extending from the area where the chemical reagent is deposited to a location away from the chemical reagent. The chemical reagent positioned on the lancet undergoes a reaction with the bodily fluid that creates an electrical potential between the two ends of the electrical contacts (19, 20). |
