A point of care testing assay system for determining the presence and/or amount of an analyte of interest in a sample, and methods for using such assay system, are disclosed. The system comprises a microfiuidic means capable of performing testing with low sample volume in a sample matrix, and having high sensitivity and substantially a 5-log wide dynamic range and capable of performing an assay in approximately fifteen minutes, and in which the microfiuidic means comprises a microfiuidic testing cartridge with associated electronics, a precision pipettor, a high sensitivity detection module, a motion stage, and an on-board electronics display means that can be read by a user as an indication of the presence and/or amount of the analyte in the sample.

Point of care testing assay system using novel microfluidics

This invention discloses novel improvements to conventional microtiter plates, involving integrating microfluidic channels with such microtiter plates to simplify the assay operation, Increase operational speed and reduce reagent consumption. The present invention can be used in place of a conventional microliter plate and can be easily substituted without any changes to the existing instrumentation systems designed for microtiter plates. The invention also discloses a microfluidic device integrated with sample loading wells wherein the entire flow process is capillary driven.
