Since the late 1970s, horseshoe crab blood has been approved to make what’s called the Limulus amebocyte lysate test, or the LAL test – an alarm system triggered by a type of bacteria that can cause fever, and in some cases, death.

It works like this: A mixture of lysate is made from the horseshoe crab’s amebocyte or blood cells. That fluid is added to whatever material a researcher is testing for safety. Depending on the test, the fluid will either clot or change color to signal the presence of a dangerous toxin.
