Systems, methods, and apparatus allow for capturing the results of drug tests using mobile devices. One or more implementations include apparatus that interface a mobile computing device with a drug test, while ensuring that an imaging device of the mobile computing device is optically aligned with a test display areas of the drug test. One or more additional implementations include a method for analyzing drug testing results. The method includes receiving and analyzing drug testing data, which includes an identification of a type drug testing apparatus being used at a remote testing device, and an image that visually represents a portion of a drug test. The method also includes analyzing the test results of the drug test based on the identification of the type drug testing apparatus.

Adaptable stand for mobile device based drug testing

Devices, methods and kits for conducting an assay to determine the presence or amount of an analyte in a fluid sample. The device includes a sample application element and a flow path matrix that facilitates fluidic flow by capillary action. The sample application element includes a non-absorbent or absorbent carrier that has a conjugate reagent that is readily solubilized by the liquid sample. In various aspects of the invention, the sample application element and the matrix are associated with a housing that allows for releasable contact between the element and the matrix. In other aspects, the invention includes methods using the device and kits including the device.

Lateral flow device with onboard reagents

There is provided a device for partitioning a liquefied sample into discrete volumes. The device includes a bottom member; a top member disposed adjacent the bottom member; and at least one channel member disposed between the top and bottom members. The at least one channel member is at least partially defined by the top and bottom members and has first and second end portions. The first end portion of the at least one channel has an opening to receive liquid and the second end portion of the at least one channel has a reaction compartment and a vent opening. Accordingly, when the liquefied sample is introduced to the first end portion, capillary action assists in causing the liquefied sample to travel from the first end portion to the second end portion and at least a portion of the liquefied sample is caused to remain in the reaction compartment.

Apparatus and method for liquid sample testing

A device for conducting an assay to determine the presence or amount of an analyte in a fluid sample. The device includes a flow path that facilitates fluidic flow by capillary action. The flow path has a first fluid permeable region, a second fluid permeable region, a barrier that inhibits fluidic flow between the first and second regions, and a fluidic bridge. The bridge includes a fluid permeable material overlapping at least a portion of each of the first region, the barrier and the second region.

Bi-directional flow assay device with reagent bridge

Invention performs an assay to determine presence or quantity of specific analyte in fluid sample. Representative device has two separate flow paths established sequentially in device with a single user activation step. First flow path delivers sample, and conjugate soluble binding reagents to solid phase. If analyte is present, an analyte:conjugate complex is formed and immobilized. Sample volume delivered by first path determined by absorbent capacity of solid phase, and not by amount of sample added to device. User need not measure sample volume. Sample/conjugate mixture is prevented from entering second flow path because capillary and surface energy of second flow path prevent it from being wetted by this mixture. Second flow path allows wash reagent to remove unbound conjugate and sample from solid phase to the absorbant, and optionally deliver detection reagents. Adaptable for many formats including, sandwich immunoassays, colloidal gold, sol particle, heterogeneous generic capture, and competitive assays.

Device and method for integrated diagnostics with multiple independent flow paths

Disclosed are devices and methods for performing an assay which determines the presence or quantity of an analyte in a fluid sample by detecting binding of the analyte to at least one immobilized analyte capture reagent and washing unbound material from the immobilized analyte capture reagent. The devices and methods an elongated solid phase flow matrix, including capillary channels capable of driving capillary fluid movement, and further including (i) a first region adapted for receipt of the fluid sample, (ii) a second region at which the analyte capture reagent is immobilized, (iii) a third region for application of a wash reagent capable of removing unbound substances from the second region; and (iv) an absorbent reservoir of high volume capacity. The second region is positioned intermediate to the first region and the third region and intermediate to the absorbent reservoir and the third region. The device also includes means to detect analyte bound at the second region. The flow matrix and the regions thereof are sized and positioned to cause the fluid sample to flow initially along the elongated flow matrix in one direction toward and through the second region, and subsequently, the liquid reagent to flow along the elongated flow matrix in a second direction opposite the first direction, through the second region, and into the absorbent reservoir, drawing unbound substances with it.

Disclosed are assay systems, kits, and methods for performing an assay which determines the presence or quantity of an analyte in a fluid sample by detecting binding of the analyte to at least one immobilized analyte capture reagent and washing unbound material from the immobilized analyte capture reagent. An elongated solid phase flow matrix includes: (i) a first region adapted for receipt of the fluid sample, (ii) a second region at which the analyte capture reagent is immobilized, (iii) a third region for application of a liquid wash and/or detector reagent capable of removing unbound substances from the second region; and (iv) an absorbent reservoir of high volume capacity. The second region is positioned between the first region and the third region and between the absorbent reservoir and the third region. The device also includes means to detect analyte bound at the second region. The fluid sample flows by capillary action initially along the elongated flow matrix in one direction toward and through the second region, and subsequently, liquid wash and/or detector reagent flows along the matrix in a second direction opposite the first direction, through the second region, and into the absorbent reservoir, drawing unbound substances with it.
