What are the units of LD50?

Posted April 9, 2021


Answer

LD50 is usually expressed as mg/kg bw/d. This stands for milligram of a substance per kilo of body weight administered per day. A lower LD50 value indicates a higher acute toxicity. It means that a smaller dose is sufficient to kill 50% of a group of organisms.
