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.
Fish oil is very beneficial for your cat’s health – both omega-3 and omega-6 are helpful at reducing inflammation, supporting the immune system, and maintaining joint and skin health.
The probable lethal oral dose in humans is 1.5 to 2 mg/kg. [2] Similarly, the median lethal dose for dogs, cats, and rats ranges from 0.5 to 2.35 mg/kg. [3]
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.
High-dose fish oil supplements are even available by prescription to reduce high triglycerides—fats that circulate in the bloodstream and increase heart disease and stroke risk. Still, research ...
The threshold dose is only a measure of acute toxicity since the drug or toxic substance investigated is administered at once. The consequence of long-term administration remains unknown. [27] As the threshold dose is the measured minimal response, its accuracy heavily depends on the machinery used. It is possible that further refinement is ...

LT50 is the median Lethal Time (time until death) [1] [2] after exposure of an organism to a toxic substance or stressful condition. LT50 is commonly used in toxicology studies to quantify amount of a stressor necessary to kill an organism. LT50 can be used in conjunction with EC50 (median Exposure Concentration) for even more precise ...
