Endotoxins – Quantification (Dust Samples)
Gram-negative bacteria contain structural components in their outer cell wall known as **endotoxins**. Endotoxins are **lipopolysaccharides (LPS)** that may induce inflammatory responses, predominantly affecting the respiratory system when exposure occurs through inhalation.
Elevated airborne concentrations are often observed in water-damaged or flood-contaminated buildings. Environmental dust samples can be screened in our laboratory to detect and quantify endotoxins using a **kinetic LAL (Limulus Amebocyte Lysate) assay**.
The presence of mold in a home has been correlated with increased endotoxin levels. The combination of fungal detection tests (such as ERMI or HERTSMI-2) and endotoxin testing provides a more comprehensive assessment of microbial-related contamination in buildings.
What’s Included
- Quantitative endotoxin result reported in **EU per mg of dust (EU/mg)**
- Kinetic LAL assay methodology
- Standardized laboratory processing
- Method controls and quality verification
- Final report delivered via email
Sample Type
Dust collected using sample cloths or vacuum devices
Quality Control
Our process incorporates method controls, standard curves, and verification steps to ensure reliable quantification. If a sample does not meet analytical quality criteria, you will be notified before additional processing.
Ideal For
- Evaluating Gram-negative bacterial components in indoor environments
- Assessing environmental endotoxin loading in dust
- Water-damage investigations
- Pre- and post-remediation comparisons
- Environmental monitoring and documentation
Important Information
This is a laboratory quantification test and not a medical diagnostic. Results reflect only the submitted sample. Dust represents accumulated material over time, and results depend on sampling location and collection method.
Turnaround Time
Turnaround time (TAT) is based on the option selected at the time of order.
