Bacterial Endotoxin / LAL Testing
Endotoxin testing, commonly performed using the limulus amebocyte lysate (LAL) test, is the critical quality process of detecting and quantifying bacterial endotoxins in pharmaceuticals, medical devices, or biological materials.
Endotoxins are toxic components of the outer membrane of Gram-negative bacteria. Even trace amounts of bacterial endotoxins can trigger harmful immune responses such as fever, inflammation, or septic shock. Endotoxin testing is essential for ensuring product safety and regulatory compliance in the UK, USA, and globally.
Comprehensive bacterial endotoxin testing at Lucideon
Lucideon provides comprehensive and reliable endotoxin testing services using the Kinetic Turbidimetric Method, a highly sensitive test using limulus amebocyte lysate (LAL), a trusted technique recognised by both the European Pharmacopoeia (Ph. Eur. 2.6.14) and the United States Pharmacopoeia (USP <85>).
At Lucideon, our testing helps you detect endotoxins from various sources, including bacterial contamination or leachates from raw materials and manufacturing processes. We work with clients across the pharmaceutical, biotech, and medical device sectors to deliver accurate results that support product safety and compliance.
How the kinetic turbidimetric method works
The Kinetic Turbidimetric Method is one of three established LAL methodologies (alongside gel-clot and chromogenic methods). This method monitors an increase in turbidity as endotoxins react with LAL reagent derived from the blood of the horseshoe crab. The presence of endotoxins triggers a clotting response that causes a measurable increase in turbidity that is proportional to the concentration of endotoxins.
This method is highly sensitive and is ideal for products where even trace endotoxin levels can pose a risk, thus ensuring compliance with stringent pharmaceutical and medical device regulations in the UK, USA, and globally.
Our endotoxin tests are conducted in line with the European Pharmacopoeia 2.6.14 and United States Pharmacopoeia (USP) 85.
Using an extraction process, our testing detects any endotoxins that may have adhered to device surfaces or entered solutions throughout the manufacturing process.
