True or False. Does a chemical with a LD50 of 1000mg over kg have less toxicity than one with LD50 of 100mg over kg?
True. The chemical with an LD50 of 1000mg/kg is less toxic than the one with an LD50 of 100mg/kg. LD50 is the lethal dose at which 50% of the test subjects die, so the higher the LD50 value, the less toxic the chemical is considered.
What color tube for a phenobarbital level?
A lavender/purple top tube is typically used for collecting blood specimens for phenobarbital level testing. This tube contains EDTA as an anticoagulant.
What is the formula used in calculation of ld50 of a substance?
LD50 ('50%-Lethality' dose) is a meaured value from many statical investigations. So there's only a good definition on how it should be 'measured' and can not be calculated from other values by formula.
What does LD50 measure?
LD50 measures the lethal dose of a substance that causes death in 50% of the test subjects, typically expressed in milligrams of substance per kilogram of body weight. It provides a standardized way to compare the toxicity of different substances.
What is the LD50 of sarin?
In toxicology, the median lethal dose, of a toxin is the dose required to kill half the members of a tested population after a specified test duration. LD50 figures are frequently used as a general indicator of a substance's acute toxicity.
Why is the LD50 of a mouse different from a human's LD50?
ld50 for lamotrigine

Will Phenobarbital crystallize in D5?

Phenobarbital and alcohol?

What is the LD50 standard?
1mg/kg
What is the LD50 of methanol for a 100 gram rat?
The LD50 of methanol for rats is typically around 5628 mg/kg. To calculate the LD50 for a 100 gram rat, you would multiply the LD50 value by the weight of the rat in kilograms (100 grams = 0.1 kg) to get an estimated lethal dose.
