The present invention generally relates to a wearable electronic device that collects information about test sample using an optical sensor. The wearable device photographs and analyzes one or more organic samples placed on one or more immunoassay regions of a test strip in order to reveal information about the sample. The wearable electronic device may also sequentially photograph a plurality of individual organic samples applied to different immunoassay regions of a test strip.

Electronic test devices and methods include data transfer capabilities. In one implementation, an assay device includes wireless communication capabilities to send assay result decisions and/or values to a separate processing and display device such as a smartphone. In another implementation, light sources are modulated both for performing an assay and encoding and transmitting a result of an assay.

In one embodiment, a diagnostic system for biological samples is disclosed. The diagnostic system includes a diagnostic instrument, and a portable electronic device. The diagnostic instrument has a reference color bar and a plurality of chemical test pads to receive a biological sample. The portable electronic device includes a digital camera to capture a digital image of the diagnostic instrument in uncontrolled lightning environments, a sensor to capture illuminance of a surface of the diagnostic instrument, a processor coupled to the digital camera and sensor to receive the digital image and the illuminance, and a storage device coupled to the processor. The storage device stores instructions for execution by the processor to process the digital image and the illuminance, to normalize colors of the plurality of chemical test pads and determine diagnostic test results in response to quantification of color changes in the chemical test pads.

A diaper, having urine detection functionalities, comprises a urine isolation layer, an absorbent core layer and an outer layer. A urine detection device is disposed in between the urine isolation layer and the absorbent core layer. The urine isolation layer has an open end embedded in a sleeve of the absorbent core layer. The urine detection device comprises a detection circuit and a test paper composite.
