If after injection with the test substance an animal developed signs of infection – this might take up to forty eight hours – the pattern was determined to be contaminated (and the rabbit died). The invention of LAL has saved numerous rabbits from fatal testing, however in turn hundreds of thousands of crabs every year take part in an involuntary blood drive.
