System, method, and computer program product for improving the accuracy of blood glucose measurements in a blood glucose meter by compensating for thermal effects of the glucose meter hardware. A machine learning model is used to predict the reaction site temperature on a blood glucose test strip based on one or more temperature measurements and device status information. The model receives several inputs including at least one temperature measurement sensed near the reaction site as well as device usage and other factors that may influence the reaction site temperature. The model provides a predicted reaction site temperature to the glucometer software or firmware to be used in a blood glucose calculation.

The present invention discloses an electrophoretic chip comprising: (a) a non-conductive substrate designed to support elements of said electrophoretic chip; (b) an electrode structure for conducting current through said electrophoretic chip, printed on said non-conductive substrate and comprising a counter electrode and at least one working electrode, each electrode comprising a conductive low-resistance ink layer printed on the non-conductive substrate, and a carbon ink layer printed on top of and fully or partially covering said conductive low-resistance ink layer; (c) a dielectric ink insulator layer placed on top of, and covering, said electrode structure, said dielectric ink insulator layer having at least one opening above the counter electrode and at least one opening above said at least one working electrode, thereby forming at least one addressable location; and (d) a molecule capturing matrix spotted on and covering said at least one addressable location, thereby creating at least one microgel region.

The invention relates to a direct sample collection pad for assay diagnosis of a sample without introducing an additional sampling device into the assay method. This simplifies the system and method of sample collection and assay diagnosis, thus reducing waste and potential for patient irritation or injury during diagnosis.

In one configuration, a handheld compound tester to process and detect presence of a compound in a tablet is disclosed. The handheld compound tester may include a sampling chamber configured to receive a tablet and a lid couplable with the sampling chamber. The coupling of the lid with the sampling chamber may cause cutting of the tablet. A liquid may be added inside the sampling chamber to create a mixture with segments of the tablet. The mixture may be then received by a housing adjoining the sampling chamber. A test strip disposed within the housing, upon contacting the mixture, may be configured to indicate a presence of the compound in the mixture.

An apparatus includes a housing, a first cavity, a volumetric pool having a limited internal volume and a squeezing mechanism. The first cavity supports a first strip having a first end portion for receiving a fluid substrate and a second end portion. The squeezing mechanism is disposed corresponding to at least a portion of a second width (W) of the first cavity in a lateral direction (Z). When the first strip is drawn along a longitudinal direction (X) such that the first end portion moves into the first cavity, the first end portion is squeezed by the squeezing mechanism to squeeze out the fluid substrate to be transferred to the volumetric pool. The fluid substrate excess to the limited internal volume of the volumetric pool overflows from the volumetric pool to retain a desired volume.

The invention provides a device for detecting an analyte in a liquid sample. The device comprises a receiving chamber for receiving an absorbent element, wherein the absorbent element is used for collecting a liquid sample; and a detection chamber configured to receive a testing element, wherein the testing element is set to test an analyte in a liquid sample, the receiving chamber is provided with a first position and a second position, when the receiving chamber is located at the first position, the receiving chamber is not in fluid communication with the detection chamber, and when the receiving chamber is located at the second position, the receiving chamber is in fluid communication with the detection chamber.

The present invention provides a device for detecting whether an analyte is contained in a fluid sample; the device includes an absorbing element used for absorbing the fluid sample and a testing element, and fluidic communication between the testing element and the absorbing element may be controlled. By means of such a test device, quantitative detection can be achieved, and the liquid sample on the absorbing element can be prevented from flowing onto the testing element in advance to start test at the same time.

Lateral flow devices, methods and kits for performing lateral flow assays are provided.

The present invention relates to a device and a method for qualitative and quantitative analysis of heavy metals and more particularly provides a device and a method for qualitative and quantitative analysis of heavy metals utilizing a rotary disc system.

There is provided a histology system that comprises a microtome configured to expose a face of a tissue block comprising a tissue sample embedded in an embedding material and remove one or more tissue sections from the sample, a hydration system configured to hydrate the tissue block by depositing a hydrating liquid on the face of the tissue block, and a transfer system configured to transfer the one or more tissue sections from the microtome to one or more slides. In some embodiments, the hydration system is configured to produce droplet condensation of the hydrating liquid and deposit the condensation on the face of the tissue block.
