Bacterial endotoxins Test
Bacterial endotoxins test is an assay to detect and quantitate bacterial endotoxins which causes heat or feaver within the body.
In the medical device industry it are the endoxins, a component of the cell wall of gram negative bacteria, that usually causes the pyrogenic reaction.
Bacterial endotoxins are very difficult to remove, heat stable and toxicity is not dependant on the presence of the bacterial cell. They often remain present, even after the cells die and are considered the by-product of lysis for certain types of microorganisms.
It is thought that water supply is the most likely source of gram-negative bacteria of which the outer cell wands contain endotoxins. To ensure that the process does not contribute endotoxins to the final product routine monitoring of water systems and incoming materials can help.
A bacterial endotoxins test is performed as a part of lot release testing for medical devices to ensure its endotoxine free. The test need to be performed for medical devices with direct or indirect contact to the lymphatic system, cardiovascular system or cerebrospinal fluid.
Micro-Serve provides bacterial endotoxins tests for serveral areas of the manufacturing and production including:
- Final poduct release testing
- Raw materials testing
- Bulk lot release testing
The bacterial endotoxins test is also know as the Limulus Amebocyte Lysate (LAL) test.
