Abstract: A method for a mobile computing device with a camera and a screen to measure a test strip in a test strip module includes, in a calibration phase before a sample is introduced to a reaction area on the test strip, detecting with the camera an ambient light effect when the test strip module is mounted on the face of the mobile computing device. In a measurement phase after the sample is introduced to the reaction area on the test strip, the method also includes illuminating the test strip with a light provided by a light source area on the screen, detecting with the camera one or more colors of the reaction area, correcting the detected one or more colors for the ambient light effect, correlating the corrected one or more colors to an analyte property, and displaying a value of the analyte property on the screen.

Abstract: A method to process an image to determine a biological property associated with a test strip (221, 313, 323, 333, 413, 423, 513, 523) in a test strip adaptor (120, 220, 620, 720). The method includes receiving the image captured by a mobile computing device (100, 600, 700) and determining whether the received image includes sensitive information. In response to determining that the image includes sensitive information, the method further includes overwriting the image with a later received image before the image can be saved as a file. In response to determining that the image does not include sensitive information, the method further includes identifying a characteristic configuration associated with the test strip (221, 313, 323, 333, 413, 423, 513, 523) and determining the biological property based on the image and the characteristic configuration.

Abstract: A method is provided for a portable computing device to read a reaction area on a test strip, which is located in a peripheral device placed over an image sensor and a light source of the portable computing device. Light is provided with the light source, which the peripheral device directs to the reaction area. An image including the reaction area is captured with the image sensor. An analyte characteristic is determined based on a color of the captured reaction area in the image.

Abstract: Example methods are provided to improve placement of an adaptor (210,220) to a mobile computing device (100) to measure a test strip (221) coupled to the adaptor (220) with a camera (104) and a screen (108) on a face of the mobile computing device (100). The method may include displaying a light area on a first portion of the screen (108). The first portion may be adjacent to the camera (104). The light area and the camera (104) may be aligned with a key area of the test strip (221) so that the camera (104) is configured to capture an image of the key area. The method may further include providing first guiding information for a user to place the adaptor (210,220) to the mobile computing device (100) according to a position of the light area on the screen (108).
