Benefits of technology

[0103]The easily usable, mass-producible, and inexpensive LOC device accepts a biological sample through its sample inlet and performs parallel amplification of the target genetic sequences in the sample, utilizing reagents stored in the LOC device's reagent reservoirs.
[0104]The amplification of target nucleic acid sequences increases the sensitivity and signal-to-noise ratio of the assay system. Furthermore, the parallel amplification chambers allow separate targets or

Problems solved by technology

Insufficient stringency can result in a high degree of nonspecific binding.
Excessive stringency can lead to a failure of appropriate binding, which results in diminished sensitivity.
Despite the advantages that molecular diagnostic tests offer, the growth of this type of testing in the clinical laboratory has been slower than expected and remains a minor part of the practice of laboratory medicine.
This is primarily due to the complexity and costs associated with nucleic acid testing compared with tests based

Overview

[0233]This overview identifies the main components of a molecular diagnostic system that incorporates embodiments of the present invention. Comprehensive details of the system architecture and operation are set out later in the specification.

[0234]Referring to FIGS. 1, 2, 3, 123 and 124, the system has the following top level components:

[0235]Test modules 10 and 11 are the size of a typical USB memory key and very cheap to produce. Test modules 10 and 11 each contain a microfluidic device, typically in the form of a lab-on-a-chip (LOC) device 30 preloaded with reagents and typically more than 1000 probes for the molecular diagnostic assay (see FIGS. 1 and 123). Test module 10 schematically shown in FIG. 1 uses a fluorescence-based detection technique to identify target molecules, while test module 11 in FIG. 123 uses an electrochemiluminescence-based detection technique. The LOC device 30 has an integrated photosensor 44 for fluorescence or electrochemiluminescence detection...
