General
What is PathoTrace?
PathoTrace is a small card that tests surfaces for bacteria and mold. You place it, wait a day, and read the result by color. It works without a lab or any equipment.
Is this a medical test?
No. PathoTrace tests the environment, not people. It looks for microbial growth on surfaces and in the air. It is not meant to diagnose or treat any condition. If you have a health concern, talk to a doctor.
Using it
How do I use a card?
Peel the backing and place the card where you want to test, like near a vent or under a sink. Leave it for 24 hours, then take a photo with the app to get your result.
How should I store unused cards?
Keep them sealed in their pouch in a cool, dry place. Stored this way, they last about 12 months.
Do I need special lighting to scan?
The app adjusts for most indoor lighting. For the best read, avoid direct sunlight and heavy shadows when you take the photo.
How it works
What does the result mean?
The card holds a dye that changes color as microbes grow. Blue means the surface is clean. The more it shifts toward magenta, the more growth is present.
Can it identify a specific germ, like E. coli?
Not yet. The card tells you how much microbial activity is present. It does not identify a specific bacteria or virus.
