A method is disclosed for determining concentration of an analyte in a body fluid with a mobile device having a camera. The camera captures an image of an optical test strip having a test field. The analyte concentration value is determined from color formation of the test field. Provided in the mobile device is a correlation for transforming color formation of the test field into analyte concentration. Also provided in the mobile device is an item of clearance information indicating a level of confidence for the correlation. When the item of clearance information indicates a sufficient level of confidence for the correlation, the mobile device indicates to a user that the capturing of the image does not require using a color reference card. Further disclosed are a method of controlling analytical measurements, a mobile device, a system for controlling analytical measurements and computer programs for performing and/or controlling analytical measurements.

A method for analyzing a biological fluid specimen. The collection cartridge is inserted into a reader. The plurality of reactive elements of the collection cartridge following insertion of the collection cartridge is optically read recurrently. The first color change of at least one reactive element of the collection cartridge is detected and dated following the recurrent optical reading. The biological fluid specimen from the collection cartridge is analyzed following the detection of the color change of at least one reactive element of the collection cartridge.

An application-analysable bodily fluid testing equipment (100, 200, 300) is provided. The application-analysable bodily fluid testing equipment comprises at least one testing region (109, 209, 309) sensitive to an indicator of a bodily condition in bodily fluid from which image data is capturable and analysable by an associated application on a device. The bodily fluid testing equipment further comprises a handling indicator (107, 207, 307) indicating an area of the equipment for a user to hold during the application of a bodily fluid to the at least one testing region, and during capture of the image data for analysis of the bodily fluid applied to the at least one testing region using the application on the device.

A method for determining an indicator of a bodily condition in an image of a bodily fluid testing equipment captured by an electronic device is provided. The method comprises determining colour data of a first bodily fluid testing region (109, 209) of a bodily fluid testing equipment (100, 200) from image data of the bodily fluid testing equipment, determining colour calibration data of at least one background sub-region (543) of a background region (545) of the bodily fluid testing equipment, calibrating the colour data based upon the determined colour calibration data, determining whether an indicator of a bodily condition has interacted with the first bodily fluid testing region, and providing an output, wherein the output is based upon whether the indicator of the bodily condition has interacted with the first bodily fluid testing region.

A lateral flow bodily fluid testing system is provided. The system comprises an application-analysable bodily fluid testing equipment (100, 200, 300) and an electronic device (1001) comprising a camera (1002) and one or more processors (1004). The one or more processors are configured to acquire image data of the application-analysable bodily fluid testing equipment with the camera of the electronic device, perform testing of bodily fluid applied to the application-analysable bodily fluid testing equipment using the image data to determine whether indicators of one or more bodily conditions are present in the applied bodily fluid, and output a result indicating whether the indicators of one or more bodily conditions are present in the applied bodily fluid.

A test strip for urinalysis is provided, the test strip including a reagent pad for detecting a concentration of a selected analyte, the reagent pad attached to the test strip and comprising a substrate and an analyte detection system retained thereon, the analyte detection system including a plurality of components necessary for detection of the selected analyte, wherein at least one of the plurality of components is a variable component, the variable component immobilized on the substrate at a plurality of amounts on the reagent pad.

A portable detection kit for identifying the presence of cannabinoids is provided and includes a colorimetric dye, a catalytic reagent, a solvent, a surfactant, and a delivery device containing a solvent or solvent mixture including the solvent. The delivery device is configured to deliver a portion of the solvent or solvent mixture to a target residue to form a sample residue. The colorimetric dye is configured to undergo a chemical reaction when the sample residue contains a cannabinoid. The chemical reaction is configured to produce a visible color change that corresponds to a predetermined cannabinoid of a plurality of cannabinoids.

A mobile device based multi-analyte testing analyzer for use in medical diagnostic monitoring and screening, and a method of manufacturing the same are disclosed. A reflectance based, colorimetric test strip reader for use with a mobile device having a jack plug receiving socket, said test strip reader adapted for removably receiving a test strip having a test strip longitudinal axis, comprising a housing; a jack plug operably coupled to and extending from said housing and adapted for operable coupling with said jack plug receiving socket; a test strip adapter including structure defining a test strip receiving channel; a light source oriented within said housing for directing light toward said test strip receiving channel to illuminate a test strip arranged within said test strip adapter; and a light sensor oriented within said housing to sense light reflected from a test strip carried by said test strip receiving channel.

The present invention provides a detection device, and the device comprises a testing element, wherein the testing element comprises a detection area used for detecting a presence of an analyte in a liquid sample; and a transparent area through which the test result on the detection area is read, and the transparent area includes a hydrophilic area and a hydrophobic area. Thus, the detection device reduces formation of droplets on the transparent area is reduced, that is, it avoids formation of a mist layer on the transparent area; or avoids accumulation of small droplets on the transparent area, thus to make the result on the test area be clearly read.

The present disclosure provides compositions and methods for detecting the presence of neutralizing antibodies in a sample. Unlike conventional assays, the methods provided herein do not require the use of live virus or virus pseudoparticles to identify neutralizing antibodies.
