A handheld diagnostic test device includes a port to removably receive a test cartridge, an element connected with an electronic device, and sensors for detection of test data from a biological or environment sample after reaction with reagents onboard the cartridge. The test device also includes memory storing algorithms for upload to the electronic device to enable a processor thereof: to await elapse of a pre-determined time following reaction of the sample with the reagents; to thereafter instruct the sensors to detect the test data; to generate presentation data based on the test data; and to present the presentation data from a presentation element of the electronic device to a user. A related method includes a connecting step, an uploading step, a presentation step, a cartridge inserting step, a waiting step, a sensing step, and an electronic device processing step.

Electronic test devices and methods include data transfer capabilities. In one implementation, an assay device includes wireless communication capabilities to send assay result decisions and/or values to a separate processing and display device such as a smartphone. In another implementation, light sources are modulated both for performing an assay and encoding and transmitting a result of an assay.

Methods and devices to monitor an analyte in body fluid are provided. Embodiments include continuous or discrete acquisition of analyte related data from a transcutaneously positioned in vivo analyte sensor automatically or upon request from a user. The in vivo analyte sensor is coupled to an electronics unit holding a memory with instruction to cause processing circuitry to initiate a predetermined time period that is longer than a predetermined life of the sensor, during the predetermined time period, convert signals from the sensor related to glucose to respective corresponding glucose levels, without relying on any post-manufacture independent analyte measurements from a reference device, and at the expiration of the predetermined time period, disable, deactivate, or cease use of one or more feature.

A non-invasive analyte sensor that includes first and second non-invasive analyte sensor assemblies each of which can emit transmit signals that are in a radio or microwave frequency range of the electromagnetic spectrum into a target and can detect responses resulting from emission of the transmit signals into the target.

A portable detector is disclosed for detecting certain analytes of interest, such as genetic material (e.g., nucleic acids). The detector includes a reading component for the detection of the analytes, and control circuitry for controlling operation of the reading component. Processing circuitry may be included to perform both primary analysis of acquired data, and where desired, secondary analysis. Where desired, some or all of the computationally intensive tasks may be off-loaded to enhance the portability and speed of the device. The device may incorporate various types of interface, technologies for reading and analysis, positioning system interfaces, and so forth. A number of exemplary use cases and methods are also disclosed.

An analytical method for determining a concentration of an analyte is disclosed. In this method, an image of an optical test strip having a body fluid applied thereto is obtained with a camera of a mobile device. Local temperature information is received at a current location of the mobile device from a temperature source such as a remote weather information service or temperature sensor. Additional local temperature information is received by the mobile device from a thermochromic field provided on the test strip and/or on a color reference card. A processor determines a correction temperature and/or a correction temperature function using the local temperature information. The processor also determines the analyte concentration from the image captured and taking into account the correction temperature information.
