Observational Study of Decentralized Urine Optical Interaction Patterns Associated With Environmental Microplastic and Nanoplastic Exposure (OMNU)
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.

Descrição detalhada
This is a decentralized, observational, product-development study evaluating the EcoExposure™ platform for at-home urine sample collection, preparation, and smartphone-based imaging. The study is non-clinical and is not intended to diagnose, treat, or provide health risk assessments.
Approximately [X] adult participants will be enrolled for a duration of about 12 weeks. All activities are performed remotely using the participant's own smartphone and the TrialKit platform for electronic consent, guided workflows, image capture, and data submission.
Participants will collect and prepare fresh urine samples at home according to provided instructions, capture guided photographs of the prepared samples, and upload the images along with brief feedback. Sampling occurs at the following timepoints: Day 0 (baseline), daily from Day 7 through Day 14 (intensive short-term variability assessment), and then at Days 21, 28, 42, 56, 70, and 84.
An optional technical reference ("spike") sample may be offered. Participants who choose this option will add a small volume of a known-concentration reference solution to one of their prepared urine samples before imaging. This step is solely for internal assay and workflow evaluation and will not be used for any clinical interpretation.
Primary focus areas include participant adherence and completion rates, image quality and usability, workflow feasibility in a fully remote setting, and qualitative assessment of optical signal consistency over time (including comparison of native versus optionally spiked samples for internal development purposes only).
No diagnostic claims, clinical endpoints, or treatment recommendations are involved. Results will support product development, workflow optimization, and assay calibration.

EcoExposure Urine Observational Cohort
All participants complete the same decentralized urine collection, preparation, and smartphone imaging workflow at scheduled timepoints over approximately 12 weeks.
An optional technical reference (spike) sample may be offered; participants who choose this option add a small volume of a known-concentration reference solution to one prepared urine sample before imaging.
This optional step is for internal assay and workflow evaluation only and does not create a separate analysis group or change the primary study procedures.

Difference in EcoExposure™ Optical Measurements Between Native and Microplastic/Nanoplastic-Spiked Urine Samples
Prazo: Day 0 through Day 84, at the study visit when optional spiked-sample testing is performed
|
When the optional spiked sample (urine sample where additional microplastic solution is added to the urine sample using an eyedropper) is performed, the participant's native urine sample and the spiked urine sample will be measured using the EcoExposure™ optical assay and image-analysis method.
Optical measurements from the native and spiked samples will be compared to evaluate differences in assay response at different microplastic and nanoplastic levels.
