摘要： Assays used in conjunction with a thermal contrast reader are disclosed. In the assay, the test strip includes materials that can develop a thermal response if a target analyte is present in a sample. The thermal contrast reader includes housing having an opening to receive the test strip at a test location, an energy source directed at the test location and a heat sensor directed at the test location. The heat sensor is configured to sense heating of the test strip upon activation of the heat source at the test location, if the target analyte is present in the sample. The heat sensor can provide sensor output using diagnostic circuitry coupled to the sensor output and configured to provide a diagnostic output. The diagnostic output can indicate the diagnostic condition of the patient as a function of the sensor output. The present disclosure also includes methods of detecting target analytes and kits comprising lateral flow assays and thermal contrast reader.

摘要： A portable system and method for measuring the concentration of multiple chemical or biological substances where an onsite analysis of such substances is needed. The new and original handheld sensor system uses a disposable optical test element and a spectroscopic detector that measures the test element response to specific analytes through a change in light absorbance, luminescence, and other forms of light-based response. In this way, reflection light intensities indicative of the test element response can be used to measure the concentration of the target analytes. The sensor system is also capable of being interfaced to an information processing unit or computer so that analytical data can be manipulated or stored electronically.

摘要： An assay result reading device for reading the result of an assay performed using a liquid transport carrier may include at least one light source capable of emitting light incident upon at least one of two or more spatially separated zones of the carrier, a photodetector so positioned as to be capable of detecting light emanating from each of the two said zones and generating signals representing the presence or absence of a fluid sample in the respective zone, and a computation circuit. The computation circuit may be responsive to the signals to calculate a flow rate for a fluid flowing along the carrier, compare the calculated flow rate to upper and lower limits, and reject the assay result if the calculated flow rate is outside the upper and lower limits.

摘要： A method and system for automatically analyzing the presence of an analyte in a liquid specimen of biological origin are described. The liquid specimen is added to a testing substrate that has a receptor immobilized on a portion of its surface. If analyte is present in the specimen, it will specifically bind to the receptor. A labeled reagent is added to the testing substrate which will bind to the analyte, if present, and generate a color on the testing substrate. The testing substrate is then illuminated and, using electronic equipment, a digital image of its surface is acquired and automatically scanned to locate an area that has the highest color density, which corresponds to the presence of labeled reagent. A measurement of color density, corresponding to pixels per unit area, is generated. An area peripheral to the area of highest color density, which represents background density, is also located and a measured. The presence or absence of analyte in the liquid sample is determined by adjusting the measurement of labeled reagent with the background density measurement in accordance with a predefined mathematical function. In some cases, the result of the test will be interpreted as a binary, positive/negative result according to whether the measurement taken is above or below a given threshold. In other cases, a continuous range of values may be generated from different samples that correspond to the concentration of the analyte present in each tested sample.
