A body fluid testing device includes a body member and a tissue penetrator carried by the body member. A test strip holder is carried by the body member, and a test strip is carried by the test strip holder. The test strip is capable of receiving a body fluid thereon and processing the body fluid into a form suitable for yielding test results relating to the content of the body fluid. The body member, tissue penetrator, test strip holder and test strip are designed for a single use and for disposal as a unit without disassembly.

Consolidated body fluid testing device and method

A body fluid testing device includes a body member and a tissue penetrator carried by the body member. A test strip holder is carried by the body member, and a test strip is carried by the test strip holder. The test strip is capable of receiving a body fluid thereon and processing the body fluid into a form suitable for yielding test results relating to the content of the body fluid.

A miniaturized, vented capillary channel test strip device for estimating the concentration of an analyte in a fluid is disclosed. The channel transports analysis fluid through interior capillary space defined by the plastic casing of the device. The casing is preferably manufactured by flow injection molding. The capillary channel includes a reaction and a wicking component. Movement of analysis fluid from sampling to reaction to wicking site is enabled by a gradient of capillary force. The gradient is generated by a differential in surface/volume ratio between reaction and wicking component. The reaction component is comprised of a thin reagent film embodying the reactive chemicals, as well as a rehydrating polymer. The polymer absorbs a defined volume of analysis fluid. When the analysis fluid is whole blood, the polymer absorbs blood plasma. Surprisingly and uniquely, cellular component of blood is wholly removed from the reagent film surface by the gradient of capillary force. In this fashion, the reacted test field becomes exposed for visual or instrumented quantification of analyte.
