Brief Summary
The goal of this observational study is to evaluate the feasibility and usability of at-home urine sample collection, preparation, and smartphone imaging using the EcoExposure™ platform in adults. The main questions it aims to answer are: Can participants successfully collect, prepare, and photograph urine samples at home and upload the images using a smartphone app? How consistent is image quality and participant adherence across repeated sampling over approximately 12 weeks? What is the short-term day-to-day variability in optical signals during an intensive daily sampling period? Participants will: Complete electronic consent and a brief intake questionnaire Collect and prepare urine samples at home at scheduled timepoints Capture guided smartphone photographs of the prepared samples Upload the images and provide brief feedback through the TrialKit app Optionally add a small reference solution (spike sample) to one sample for technical evaluation only The study is fully remote and lasts approximately 12 weeks. It is intended for product development and workflow validation purposes only and does not involve any diagnostic or clinical decision-making.
