    In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.

    The median toxic dose encompasses the category of toxicity that is greater than half maximum effective concentration (ED 50) but less than the median lethal dose (LD 50). However, for some highly potent toxins (ex. lofentanil , botulinum toxin ) the difference between the ED 50 and TD 50 is so minute that the values assigned to them may be ...

    The median lethal dose (LD 50) of a venom is the dose required to kill half the members of a tested population after a specified test duration. A lower LD 50 number indicates increased toxicity. There are four methods in which the LD 50 test is measured: Subcutaneous: Venom is injected into the fatty layer beneath the skin.
