LAL testing normally takes benefit of this endotoxin-delicate clotting reaction to supply a Wager assay that may be trustworthy, delicate and precise.
There exists also some proof that phosphate-made up of formulations may also be impacted by LER. Even so, the LER influence has only been noticed together formulations with the aforementioned excipients, instead of in person raw components.
