Endotoxin in Dust Kit

Quantify the bacterial-toxin load hiding in household dust.

Coming soon
What it tests for
  • Bacterial endotoxin (lipopolysaccharide / LPS), reported in Endotoxin Units (EU) per gram or per m2
Why it matters

Endotoxin is a fragment of the outer membrane of gram-negative bacteria. Inhaled, it drives airway inflammation and is associated with asthma severity, wheezing, and respiratory symptoms - independent of whether the bacteria are alive.

Levels tend to be higher in homes with pets, dampness, or poor ventilation, and matter most for occupants with asthma or COPD.

How to collect your sample

Attach the nozzle to a household vacuum and collect dust onto the filter cassette from a defined area, following the instructions. Seal in the sterile vial and return.

How the lab analyzes it

The LAL assay uses a clotting reaction derived from horseshoe-crab blood cells that is exquisitely sensitive to endotoxin, quantifying the bacterial-toxin load in the dust.

Did you know
  • The LAL test famously relies on horseshoe-crab blood - one of the most sensitive biological detectors known.
  • Endotoxin doesn't require living bacteria to cause harm; the toxin remains active in dead-cell debris.
The Sacred Sampling standard

Laboratory data — not estimates.

Independently operated, with no ties to filter or remediation companies. Every sample is analyzed by an accredited partner laboratory under EPA-referenced methods, with a documented chain of custody — and your data is yours.
