Since LPS is the main trigger for the immune response in our cells, it acts as an early signal of an acute infection. Therefore, LPS testing is more specific and meaningful than many other serological tests. [58] The current methods for testing LPS are quite sensitive, but many of them struggle to differentiate between different LPS groups.
Atlantic horseshoe crab Limulus polyphemus. Limulus amebocyte lysate (LAL) is an aqueous extract of motile blood cells from the Atlantic horseshoe crab Limulus polyphemus.LAL reacts with bacterial endotoxins such as lipopolysaccharides (LPS), which are components of the bacterial capsule, the outermost membrane of cell envelope of gram-negative bacteria.
This article needs to be updated.The reason given is: the section related to E.U. needs further updates (esp. in sections 3.2 and 4.2.2) as the directives 93/42/EEC on medical devices and 90/385/EEC on active implantable medical devices have been fully repealed on 26 May 2021 by Regulation (EU) no. 2017/745 (MDR); furthermore, Brexit triggers updates in these sections (U.K. developed their own ...
The main difference between the two is that validation is focused on ensuring that the device meets the needs and requirements of its intended users and the intended use environment, whereas verification is focused on ensuring that the device meets its specified design requirements.

An injector pen (also called a medication pen) is a device used for injecting medication under the skin. First introduced in the 1980s, injector pens are designed to make injectable medication easier and more convenient to use, thus increasing patient adherence. The primary difference between injector pens and traditional vial and syringe ...
Chemical structure of lipid A as found in E. coli [1]. Lipid A is a lipid component of an endotoxin held responsible for the toxicity of gram-negative bacteria.It is the innermost of the three regions of the lipopolysaccharide (LPS), also called endotoxin molecule, and its hydrophobic nature allows it to anchor the LPS to the outer membrane.

The practice of reusing medical devices labeled for only one use began in hospitals in the late 1970s. [8] After a thorough review by the U.S. FDA in 1999 and 2000, [8] the agency released a guidance document for reprocessed SUDs that began regulating the sale of these reprocessed devices on the market, [9] under the condition that third-party reprocessors would be treated as the manufacturer ...
