The present invention includes a body case having a biological sample sensor mounting portion on one end side, a temperature sensor (A) provided on the one end side inside the body case, a measurement portion connected to the biological sample sensor mounting portion, and a control portion connected to the measurement portion. A temperature sensor (B) is provided on one other end side inside the body case, and when measurement is performed by the measurement portion, temperature change amounts in the two end portions are compared using the temperature sensors (A) and (B). Furthermore, a measurement value obtained by the measurement portion is corrected using temperature information from either one of the temperature sensors (A) or (B) that is provided in the end portion on the side where the temperature change is smaller.

This present invention relates generally to devices, systems, and methods for performing optical and electrochemical assays and, more particularly, to devices and systems having universal channel circuitry configured to perform optical and electrochemical assays, and methods of performing the optical and electrochemical assays using the universal channel circuitry. The universal channel circuitry is circuitry that has electronic switching capabilities such that any contact pin, and thus any sensor contact pad in a testing device, can be connected to one or more channels capable of taking on one or more measurement modes or configurations (e.g., an amperometric measurement mode or a current drive mode).

A method for obtaining a point-of-collection, selected quantitative indicia of an analyte on a test strip using a smartphone involves imaging a test strip on which a colorimetric reaction of a target sample has occurred due to test strip illumination by the smartphone. The smartphone includes a smartphone app and a smartphone accessory that provides an external environment-independent/internal light-free, imaging environment independent of the smartphone platform being used. The result can then be presented quantitatively or turned into a more consumer-friendly measurement (positive, negative, above average, etc.), displayed to the user, stored for later use, and communicated to a location where practitioners can provide additional review. Additionally, social media integration can allow for device results to be broadcast to specific audiences, to compare healthy living with others, to compete in health based games, create mappings, and other applications.

One side of the surfaces of the crystal resonator 4 including an adsorbing film 46 that absorbs a sensing object on an excitation electrode 42A is pressed with the channel forming member 5 using the upper-side cover body 21 to fonn a channel 57, which runs from one end side to the other end side on one side of surfaces of the crystal resonator 4. A depressed portion 84 is disposed in at least one of: a position opposed to the channel 57 and at a surface on an opposite side of the channel 57 in the channel forming member 5, and a position opposed to the channel 57 and at a surface on the opposite side of the channel 57 in the pressing member with respect to the channel forming member 5.

Embodiments described herein relate to an analyte monitoring device having a user interface with a display and a plurality of actuators. The display is configured to render a plurality of display screens, including a home screen and an alert screen. The home screen is divided into a plurality of simultaneously displayed panels, with a first panel displays a rate of change of continuously monitored analyte levels in interstitial fluid, a second panel simultaneously displays a current analyte level and an analyte trend indicator, and a third panel displays status information of a plurality of components of the device. When an alarm condition is detected, the display renders the alert screen in place of the home screen, the alert screen displaying information corresponding to the detected alarm condition. Furthermore, the actuators are configured to affect further output of the analyte monitoring device corresponding to the detected condition.

A system and method with increased sensitivity to microorganism growth. The system includes signal processing electronic circuit connected to a consumable or vessel through two or more electrodes that fully penetrate the vessel and are in contact with the fluid contents. The electronic circuit is configured to detect a component of the total impedance of the sample, specifically the “out-of-phase” or imaginary reactance component, which has a sensitive response to organism growth in a frequency-dependent manner. The system detects changes in both the composition of charged molecules in the liquid matrix and the number of microorganisms based on monitoring the sample for change in this parameter. This results in a 5-70% reduction in time-to-detection (TTD). The system and method detect organisms in a plurality of vessel shapes, volumes, and matrix (or media) formats. The electrodes are fully immersed in a continuous body of liquid sample. The distance between electrodes may be adjusted or tuned to fit the needs of the vessel. The voltage inputs can also be adjusted to allow proper detection of the contents within the vessel.
