Abstract
An article capable of both collecting interstitial fluid and detecting an analyte in that fluid and a method for use of that article. Preferably, the article is also capable of measuring the amount of analyte in the interstitial fluid. The article can be used in conjunction with a meter that contains an appropriate detection element for determining the amount of analyte in the interstitial fluid. In one preferred embodiment, the article is a multiple-layer element comprising:(1) a layer that is capable of being placed in contact with the skin of a patient;(2) a layer that is coated over the skin-contacting layer;(3) a layer, substantially coplanar with the overcoat layer, that is capable of transporting interstitial fluid by means of chemically aided wicking;(4) a layer, overlying the interstitial fluid transporting layer, that is capable of being placed in contact with a meter, said layer having an opening therein through which light can be transmitted;(5) a layer, disposed on the surface of the meter-contacting layer that faces the skin-contyacting layer, that is capable of detecting the presence of analyte or measuring the amount of analyte in the fluid.In order to use the multi…
