Abstract
Arrangements for the detection of the presence and/or concentration of an analyte in a sample of bodily fluid include diffuse transmission, diffuse reflection and edge or waveguide illumination arrangements. A vertical flow assay arrangement and/or technique is also disclosed, and includes a detection component that can be in the form of an array of optical detection elements. A number of assay pad constructions are described which may include at least one or more of the following components: a prefilter component, a reflective component, a membrane component, a reagent component, a mesh component, and a component to prevent lateral spreading.

59. A device for conducting an assay to determine the concentration of an analyte in a sample of bodily fluid, the device comprising:
-
a skin-penetration member configured to collect the sample; a sample collection chamber configured to receive the sample from the skin-penetration member; an assay pad in communication with at least one opening of the sample collection chamber, assay pad comprising a reagent adapted to produce a reaction when exposed to the analyte; and at least one detector disposed relative to the assay pad so as to detect the reaction, wherein the sample collection chamber is configured such that when the sample is received by the sample collection chamber the sample flows laterally or axially through the chamber, then flows vertically toward the assay pad. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67)
