  • Multiplexed lateral flow assay device
    Patent number: 11906515
    Abstract: A multiplexed lateral flow device includes an impermeable internal reservoir having an opening to receive a sample deposition. A fluid distributor pad is arranged in fluid communication with a lower surface of the internal reservoir. The fluid distributor pad includes a paper based microfluidic element having a pattern of a hydrophobic material to distribute a portion of the sample deposition substantially equally among a plurality of flow paths. Lateral flow assays having a plurality of flow lines are aligned with flow paths of the distributor pad. An impermeable top cover has a first window arranged over the opening of the internal reservoir, and at least a second window arranged over the test results of the lateral flow assays. A housing element houses the reservoir, the distributor pad and lateral flow assays.

  • ARTIFICIAL CALIBRATION VIRUS TO CONTROL HIV VIRAL LOAD TESTS BY PCR IN REAL TIME
    Publication number: 20100291538
    Abstract: The present invention refers to the design of an artificial calibrating virus (ACV), as well as a methodology quality guarantee system, which has controlling characteristics in the performance of all the stages carried out during a detection and/or quantification molecular test. More specifically, the referred to ACV is used for the validation and calibration of quantitative determinations of circulating viruses in blood plasma samples by means of polymerase chain reaction (PCR) technology in real time (or ‘real time PCR’).
