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 lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 (lethal concentration and time) of a toxin, radiation, or pathogen is the dose required to kill half the members of a tested population after a specified test duration.

Other reports list the lethal dose (LD50) at 24 to 30 mg per kilogram when given by IV. The LD50 is when half the dogs die at that dose, so the toxic dose may be a lot lower, and if your dog has a ...
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.
It is the minimum dose or concentration of a drug that produces a biological response in 50% of a population being studied. Median lethal dose: For either drugs or toxins, it is a toxic unit that measures the minimum dose that causes death (lethal dose) in 50% of cases. Median toxic dose
For an adult human, exposure to 2 Gy from an unfocused radiation source such as an excursion will cause radiation sickness but is not definitely lethal; about 4.5 to 5 Gy is the LD 50, or median lethal dose; 8 Gy is the LD 99. [6] [7] [8] Kelley had received more than 7 times the LD 50.
Prescriptions for lethal doses of medication in Oregon increased by nearly 30% in 2023, ... Some out-of-state deaths are not reported; some people die before taking the lethal dose; and some 5% ...
