Cool name

LD50

From Simple English Wikipedia, the free encyclopedia
The name LD50 is an abbreviation for "Lethal Dose, 50%" or median lethal dose. It is the amount of the substance required (usually per body weight) to kill 50% of the test population.

The test was created by J.W. Trevan in 19271 but has been phased out.2 The U.S. Food and D*** Administration has begun to approve non-animal alternatives to LD50, in response to research cruelty concerns and the lack of validity/sensitivity of animal tests as they relate to humans.3
