First Claim
1. An apparatus for use in determining the concentration of an analyte in a body fluid, said apparatus comprising:
- a housing;
a sample chamber;
a lance mounted within and moveable with respect to said housing toward a lance site, said sample chamber being in fluid communication with said lance site upon movement of said lance to said lance site;
said sample chamber defined by at least one inner surface, said chamber having an interior volume, all of said at least one inner surface and said interior volume being inert with respect to said body fluid;
said interior volume being no greater than about 0.5 μ

Abstract
An analyte detection system for analysis of a body fluid is provided, comprising an analysis portion and a sample collection portion which is configured to be removably coupled to the analysis portion. The analysis portion comprises a detector configured to detect electromagnetic radiation and a source of electromagnetic radiation. The source is positioned with respect to the detector such that electromagnetic radiation emitted by the source is received by the detector. The sample collection portion comprises a housing, a lance and a sample chamber. The lance is mounted within and moveable with respect to the housing. The sample chamber is configured to be positionable, upon coupling of the sample collection portion to the analysis portion, with respect to the source and detector such that at least a portion of any electromagnetic radiation emitted by the source passes through the sample chamber prior to being received by the detector.
