This invention is in the field of medical devices. Specifically, the present invention provides portable medical devices that allow real-time detection of analytes from a biological fluid. The methods and devices are particularly useful for providing point-of-care testing for a variety of medical applications. In particular, the medical device reduces interference with an optical signal which is indicative of the presence of an analyte in a bodily sample.

Devices and methods incorporate lysis agents into a point-of-care testing device. The sample is loaded, and then the sample travels until it encounters a lysis agent. The lysis agent is preferably pre-loaded onto the collection device. In a preferred embodiment, the initially lysis agent is localized between the sample application zone and the conjugate zone. The lysis agent is preferably soluble or miscible in the sample transport liquid, and the lysis agent is solubilized and activated upon contact with the sample transport liquid. The sample transport liquid then contains both lysis agent in solution or suspension and sample components in suspension. Any lysis-susceptible components in a sample, then being exposed in suspension to the lysis agent, are themselves lysed in situ. The running buffer then carries the analyte, including any lysis-freed components, to the detection zone.

Disclosed herein is a fully-integrated, disposable biochip for point-of-care testing of clinically relevant parameters. Specifically, in accordance with an embodiment of the present invention, the biochip is designed for POCT (point-of-care-testing) of an array of metabolic parameters including partial pressure of oxygen, Glucose, and Lactate concentration from venous blood samples. The biochip is fabricated on a low-cost plastic substrate using mass manufacturing compatible fabrication processes. Furthermore, the biochip contains a fully-integrated metallic micro-needle for blood sampling. The biochip also uses smart passive microfluidics in conjunction with low-power functional on-chip pressure generators for microfluidic sequencing. The design, configuration, assembly and operation of the biochip are ideally suited for a disposable biochip specifically targeted towards POCT applications.
