Analytical systems, devices, and cartridges therefor

Abstract

Described here are systems, devices, cartridges, methods, and kits for detecting or quantifying at least two different analytes using at least two different techniques, in a single sample. The cartridges typically comprise at least two test sites and the location of at least one test site is not dependent on a corresponding measurement device. The systems generally comprise a device, memory, and a processing module. The device comprises a light source, an array detector, and a port configured to accept at least a portion of a cartridge. The processing module is configured to perform an image analysis of the cartridge. The methods comprise the steps of acquiring calibration information, acquiring an image of the cartridge, performing an image analysis, and cycling through specific detection or quantification techniques corresponding to the techniques required by the test sites. Computer readable media are also described.

Description

technical field [0001] The present invention relates generally to multi-analyte detection and quantification, and more particularly to multi-analyte detection and / or quantification using more than one measurement technique, a single sample, and a single device. Background technique [0002] Currently, it is common practice to detect or quantify separated analytes using separation detection or quantification techniques. For example, enzymatic assays, immunoassays, chemical colorimetric assays, fluorescent labeling and measurement, chemiluminescent labeling and measurement, and electrochemiluminescent labeling and measurement are some exemplary well-known analytical techniques that can be used to detect the presence of a variety of analytes . Many of these techniques are performed on a test strip or sample cartridge. [0003] Test strips typically have specific test zones or test sites at various locations on the strip. Certain of these strips contain arrays of test sites f...

These operations require the user to have a more detailed knowledge of QC testing needs and instrument maintenance than many potential users are willing or able to acquire

In addition, when new tests, algorithms, and procedures are developed, devices that do not have the ability to automatically update data will inevitably be eliminated
