The present disclosure relates to a process that comprises, in at least one embodiment: accessing a camera via an application; prompting a user to induce blanching for a time period of 10 seconds; processing information from the camera to automatically detect one or more fingernails for each of the one or more fingers; accessing video data from the camera; computing a capillary refill time; causing a display screen to display the capillary refill time; and transmitting the capillary refill time to a computing device.

Capillary refill image processing systems and processes

A smartphone-based hemoglobin (Hgb) assessment application quantitatively analyzes pallor in patient-sourced photos using image analysis algorithms to enable a noninvasive, accurate quantitative smartphone app for detecting anemia. A user takes a photo of his/her fingernail beds using the app and receives an accurate displayed Hgb level. Since fingernails do not contain melanocytes, the primary source of color of these anatomical features is blood Hgb. At the same time, quality control software minimizes the impact of common fingernail irregularities (e.g. leukonychia and camera flash reflection) on Hgb level measurement. Metadata recorded upon capturing the image is leveraged for determining a users' Hgb level thereby eliminating the need for external equipment. A personalized calibration of image data with measured Hgb levels improves the accuracy of the application.

Systems and methods for quantitative diagnosis of anemia

Diagnostic kits and methods configured to rapidly and non-invasively determine physiologic levels of hemoglobin. A diagnostic kit may include a chamber pre-filled with an indicator, the indicator solution including a tetramethylbenzidine (TMB) solution, the indicator being configured to change color; a collection device configured to collect a test sample from a subject. The kit may also include a hemoglobin physiologic level identifier legend, the legend indicating 1) at least one color of the indicator and 2) a physiologic level and/or range of the hemoglobin and/or disease state associated with the color.
