Abstract: An assay device is disclosed comprising a housing and a test portion, electronic circuitry and an optical assembly each a least partially located in the housing. The test portion comprises one or more test zones adapted to receive an analyte and a fluorescent label associated with the analyte, the fluorescent label being excitable by excitation light and adapted to emit emission light upon excitation by excitation light. The electronic circuitry comprises one or more light sources and one or more light detectors. The optical assembly comprises one or more excitation light guides adapted to guide excitation light from the one or more light sources to the one or more test zones, and/or one or more emission light guides adapted to guide emission light from the one or more test zone to the one or more light detectors.

Abstract: Apparatus is disclosed for identifying at least a first target condition in a human or animal body. The apparatus comprises one or more test portions for identifying a first analyte in a biological sample from the body, the first analyte providing a marker of the first target condition, and a second analyte in the biological sample, the second analyte being different from the first analyte. The apparatus is configured to identify the first target condition in the body based on the identification of both the first and second analytes. In one embodiment, the first target condition is pregnancy, the first analyte is human chorionic gonadotropin (hCG) and the second analyte is luteinizing hormone (LH).

Abstract: The present disclosure relates to devices and methods for identifying conditions in a human or animal body, such as pregnancy or ovulation. For example, the present disclosure relates to devices and methods for identifying pregnancy or ovulation, which devices and methods are adapted to mitigate the “hook effect”, thereby improving accuracy of the devices and methods.

Abstract: An assay device is disclosed comprising a housing (10) and a test portion (2), electronic circuitry (30) and an optical assembly (41), each at least partially located in the housing (10). The test portion (2) comprises one or more test zones (2E, 2F) adapted to receive an analyte (22) and a fluorescent label associated with the analyte, the fluorescent label being excitable by excitation light and adapted to emit emission light upon excitation by excitation light. The electronic circuitry (30) comprises one or more light sources (31, 32) and one or more light detectors (33). The optical assembly (41-44) comprises one or more excitation light guides (41, 44) adapted to guide excitation light from the one or more light sources (31, 32) to the one or more test zones (2e, 2f), and/or one or more emission light guides (43, 44) adapted to guide emission light from the one or more test zones (2e, 2f) to the one or more light detectors (33).
