Abstract

A microfluidic-based lab-on-a-test card is described. The test card is used with a point-of-care (POC) analyzer. The test card is designed to receive a sample and then, with the use of the POC analyzer, quantify or count a particular substance in the sample. The test card may be comprised of multiple layers. In one embodiment, the test card includes a primary separation chamber with a filtration surface, a trapping channel, and a particle detector. The test card may also include a nanowire sensor.
