Pinpointing LAL for a remarkably sensitive detector of endotoxins was a twentieth-century medical security breakthrough. Now, even so, critics are raising questions on environmental impacts and the procedure for reviewing and approving synthetic alternatives to horseshoe crab blood.

Often known as the rabbit pyrogen take a look at, it essential scientists to inject intravenous prescription drugs into rabbits, then observe the animals. A feverish rabbit intended that a batch of medicine was contaminated.
