Endotoxins are toxic substances found on the outer membrane of certain bacteria and can accumulate in indoor dust. SimpleLab’s Endotoxin Vacuum Test kit provides certified mail-to-lab analysis of one dust sample, aiding the identification of potential exposure risks in any environment.

How Do You Test for Endotoxins?

The best way to test for endotoxins is in a certified laboratory. With SimpleLab’s Endotoxin Vacuum Test kit, testing is simple: 

  1. Collect a dust sample using a vacuum with a hose attachment and the provided materials. 
  2. Send it to a certified lab within SimpleLab’s network in the prepaid shipping box. Upon receipt, endotoxins in your sample will be measured using the Endotoxin Analysis Method EM-BC-S-2583 
  3. Receive your results in a clear digital report. 

Unlike DIY strips or swabs, method EM-BC-S-2583 utilizes selective endotoxin detection in dust samples to provide accurate, lab-verified results.

Who Should Use this Test?

This kit is the right fit for:

  • Homeowners and renters curious about indoor dust quality
  • Building managers monitoring cleanliness in shared spaces
  • Caregivers and guardians needing to discern any possible hazards linked to poor indoor air quality
