If you have ever taken any form of medicine, one important study that must be conducted before that medicine is put on the market is that of the LD. 50 test.. LD 50 (lethal dose 50%) is a toxicological value that measures the dose that kills 50% of a test population over the course of 14 days. In other words, if you are exposed to this dosage, you have a 50% chance of dying within two weeks. ................
