Abstract: A method for analyzing a sample includes introducing the sample into a vessel including a cation-exchange resin, where the cation-exchange resin has a high affinity to one or more interferent species in the sample, directing the sample through the cation-exchange resin to thereby capture one or more interference species in the cation-exchange resin to purify the sample, and releasing the purified sample from the vessel. Additionally, a method for analyzing a sample includes receiving an image depicting a diagnostic test region and a color reference chart, converting a test region image portion of the image to an analytical color space, determining first and second coordinate values characterizing the test region image portion in the analytical color space, and providing a quantitative measurement of an analyte of interest in the sample based on the first and/or second coordinate values and a predictive formula based on the color reference chart.

Abstract: A biomedical measuring device, such as a test strip, has a simple structure, by which analyte can be measured easily using a small amount of specimen. In embodiments, the test strip generally includes a plastic first film layer having structure defining an aperture for retaining the reacting components, a porous membrane coupled to an inner-facing surface of the first film layer and configured to reduce background signal, an absorbent pad coupled to the porous membrane and first film layer to sandwich the porous membrane therebetween, the absorbent pad being configured for rapid absorption, and a plastic second film layer coupled to the absorbent pad, the second film layer being configured to provide a barrier to prevent liquid from leaking out of the test strip during use. The test strip can be easily used with an optical sensing device coupled to or containing an analyzer device (or reader device) for quickly detecting and measuring the analyte concentration.

Abstract: In some implementations, a system may identify one or more account identifiers associated with a user account and corresponding to one or more account types. The system may determine an action to perform if account information associated with the user account or with a particular account identifier satisfies a condition. The system may transmit, to a user device, user interface (UI) data associated with an icon-based UI element. The UI data indicates a rectangular-shaped element, of the icon-based UI element, associated with the particular account identifier, and an interactable icon, of the icon-based UI element, positioned within a bottom portion of the rectangular-shaped element. The interactable icon is representative of the action. The system may include receiving, from the user device, interaction data indicating an interaction, by a user of the user device, with the interactable icon. The system may perform the action based on receiving the interaction data.

Abstract: In some implementations, a system may receive a user identifier associated with a user account, and may identify account identifiers associated with the user account. The system may obtain account information associated with the account identifiers, and may determine priority levels for the account identifiers based on the account information. A primary account identifier may be associated with a highest priority level. The system may transmit a first set of user interface (UI) data indicating account UI elements, corresponding to the account identifiers, and an order of the account UI elements based on the priority levels. A primary account UI element, corresponding to the primary account identifier, may be arranged first in the order. The first set of UI data may indicate a first set of the account information to be visually presented on the account UI elements and associated with the account identifiers corresponding to the account UI elements.

Abstract: In some implementations, a system may receive interaction data indicating an interaction time and amount. The system may categorize the interaction in a category of a plurality of categories. For each category, the system may compare a total category amount with an average category amount. The system may determine, for each category, a proportion of the total category amount relative to a total account amount. The system may transmit, to a user device, user interface data associated with a ring-shaped user interface element that includes a plurality of segments corresponding to the plurality of categories. The user interface data indicates a width of a particular segment that is based on the comparison of the total category amount for a corresponding category with the average category amount, and an arc length that is based on the proportion of the total category amount for the corresponding category to the total account amount.

Abstract: A method for analyzing a diagnostic test may include receiving an image depicting a diagnostic test, wherein the diagnostic test comprises a test region indicating a test result, validating quality of the image, locating a test region image portion of the image depicting the test region of the diagnostic test; and predicting the test result based on the test region image portion. Furthermore, a method for facilitating analysis of a diagnostic test may include receiving one or more images depicting one or more control markings on a scan surface, wherein the one or more control markings are representative of one or more predetermined test results for the diagnostic test, and verifying detection of the one or more control markings in the one or more images using at least one computer vision technique.

Abstract: In some implementations, a system may transmit a first set of user interface (UI) data indicating a UI having a first interaction element. The system may receive interaction data indicating a user interaction with the first interaction element. The system may determine one or more suggestions to provide based on one or more factors related to account information associated with a user account. The system may transmit a second set of UI data associated with a UI element and that may indicate a first portion, extending downward from a top of a display of the user device, that may include one or more second interaction elements corresponding to the suggestions, and a second portion extending upward from a bottom of the display and including a virtual keyboard. An intermediate portion of the UI may be exposed through a gap between the first and second portions of the UI element.
