Contamination testing

See what is growing in your space.

PathoTrace is a small card that finds bacteria and mold on everyday surfaces. Place it, wait a day, and read the result by color. No lab. No equipment.

How you read it

The result is a color.

The card holds a dye that reacts to living microbes. It stays blue when a surface is clean. It shifts toward magenta as bacteria grow. You match the window to the scale on the card.

How it works

Three steps.

  1. 01

    Place it

    Peel the backing and press the card onto the surface you want to test. A counter, a vent, a wall.

  2. 02

    Wait a day

    Leave it for 24 hours. The dye reacts as microbes grow. There is nothing to plug in and nothing to calibrate.

  3. 03

    Read the color

    Match the window to the scale printed on the card. Blue means the surface is clean. Magenta means something is growing.
