The IC50 values can be converted to estimate the lethal dose that kills 50 % of the animals (LD50) following the regression formula given by the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM): log LD50 (mg/kg) = 0.372 log IC50 (µg/mL) + 2.024 (ICCVAM, 2006).
How do you calculate the LD50?
The new LD50 formula (LD50 = ((ED)_50/3) × Wm × 10-4) yielded value (0.29 mg/kg) of comparative significance with reported value (0.32 mg/kg).
How is LC50 different from LD50?
LD50 and LC50 are the parameters used to quantify the results of different tests so that they may be compared. LD50 is the abbreviation used for the dose which kills 50% of the test population. LC50 is the abbreviation used for the exposure concentration of a toxic substance lethal to half of the test animals.
What does the 50 represent in LD50?
LD stands for "Lethal Dose". LD50 is the amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 is one way to measure the short-term poisoning potential (acute toxicity) of a material.

What is LC50 value?
An LC50 value is the concentration of a material in air that will kill 50% of the test subjects (animals, typically mice or rats) when administered as a single exposure (typically 1 or 4 hours).
What is LD50 value?
The median lethal dose (or LD50) is defined as the dose of a test substance that is lethal for 50% of the animals in a dose group. LD50 values have been used to compare relative acute hazards of industrial chemicals, especially when no other toxicology data are available for the chemicals.
Is LD50 and IC50 the same?
The IC50 values can be converted to estimate the lethal dose that kills 50 % of the animals (LD50) following the regression formula given by the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM): log LD50 (mg/kg) = 0.372 log IC50 (µg/mL) + 2.024 (ICCVAM, 2006).
What is an LC50 value?
An LC50 value is the concentration of a material in air that will kill 50% of the test subjects (animals, typically mice or rats) when administered as a single exposure (typically 1 or 4 hours).
What does an LD50 indicate and what are the units for this value?
An LD50 or 50% Lethal Dose value is the amount of a solid or liquid material that it takes to kill 50% of test animals (for example, mice or rats) in one dose. It is also called the median lethal dose. This is closely related to the LDLo value which is the lowest dosage reported to have killed animals or humans.
