Water, packaging, food preparation, dust, and textiles can all shape everyday contact with plastics. Pick one practical change, then use a future screening as a separate awareness snapshot.
plastic particles per liter measured in bottled water in an NIH-highlighted study — roughly 90% nanoplastics.

In one peer-reviewed study, polyethylene cutting boards were identified as the source of microplastic contamination transferred to chicken and fish during preparation.

Household dust carries fragments shed by carpets, furnishings, and packaging you already live with.

Polyester, nylon, and acrylic can shed microfibers through everyday wear and washing.
One swap to tryWash synthetics less often, on cooler cycles, and choose natural fibers where practical.

Before you order
The essentials, without the fine-print maze.
Candidate particles visually consistent with microplastics in a saliva sample, using Nile Red staining and observational microscopy. It is an awareness screening—not a diagnosis or clinically validated measurement of total exposure.
Collection takes about two minutes. Your private result is typically ready within 72 hours after the lab receives and accepts your sample; shipping time is separate.
Your collection kit, instructions, prepaid lab-return materials, our lab screening, and private digital snapshot are all included.
Yes. Multi-test plans let you compare separate observational snapshots over time. Differences are for awareness and are not a validated measure of exposure change or health improvement.
