    I’m writing a persuasive speech against animal testing, and I was wondering if there was a safer alternative to the LD50 test.

    Thanks so much

    Hey @megacdrizzle,

    The LD50 test is not only incredibly cruel to animals, it’s also totally unnecessary. Despite its decades of use, the LD50 test has never been scientifically proven to actually predict chemical effects in people. One international study found that these tests were able to predict toxicity in humans with only 65 percent accuracy––while a series of human cell-line tests was found to predict toxicity in humans with about 75 percent accuracy.

    There are so many humane, non-animal alternatives to testing on animals that are actually applicable to humans. Check them out here:

    Thanks, and be sure to e-mail us at if you have any other questions. :)
