Embodiment Construction

[0028] A device for determining the concentration of an analyte in a physiological sample is provided. The device includes a calibration device, at least one light source, and a photometric detector array having at least two detectors, namely (a) at least one calibration detector, and (b) at least one other analyte concentration determination or assay detection device. In certain embodiments, one or more detectors of the detector array may serve as both calibration detectors and analyte concentration determination detectors. The at least one calibration detector is capable of detecting a photometrically readable calibration mark from the analyte concentration measurement device container to calibrate the analyte concentration determination device based on the detected calibration mark. The at least one further detector is used to detect reflected light from an analyte concentration measuring device, such as a test strip or a hollow frustum device, which is related to the anal...

Abstract

Devices for determining the concentration of an analyte in a physiological sample are provided. The subject devices include a calibration means, at least one light source, a photometric detector array having at least one calibration detector and at least one other detector. The at least one calibration detector is capable of detecting a calibration mark from an analyte concentration measurement device container for calibrating the analyte concentration determination device. The at least one other detector is used for detecting reflected light from an analyte concentration measurement device associated with the analyte concentration determination device. The means for calibrating a component, aspect or feature of the analyte concentration determination device is based on the calibration mark. The subject invention also includes methods for calibrating a component, aspect or feature of a subject device based on the detected calibration mark. Also provided are kits for use in practicing the subject methods.

Description

technical field [0001] The field of the invention is analyte concentration determination. Background technique [0002] Analyte concentration determination of physiological samples is of increasing importance to modern society. Such assays find use in a variety of application settings, including clinical laboratory tests, home tests, etc., where the results of such tests play an important role in the diagnosis and management of various disease conditions. Analytes of interest include glucose for diabetes management, cholesterol for monitoring cardiovascular symptoms, etc. [0003] In response to the growing importance of analyte concentration determination, various protocols and devices for clinical and home analyte concentration determination have been developed. Of great interest for use in the art are analyte assay devices and methods based on optics, where a sample is illuminated with light and the reflected light is detected, wherein the amount of light detected is re...
