Rabbit Pyrogen Test Procedure
Rabbit Pyrogen Test Procedure. All in vivo rabbit pyrogen tests are performed according to usp. Rabbits have a similar pyrogen tolerance to humans, so by observing a change in body temperature in rabbits it is possible to make a determination of the presence of pyrogens.

Preparation of the sample procedure: In the case of the lal test, only endotoxins can be detected causing a safety risk. The food and water is withheld to rabbit overnight.
The Dosage For Each Rabbit Depends On Body Weight, Age, And Gender.
Rabbits have similar temperature response to endotoxins as humans. The rabbit pyrogen test and the limulus amebocyte lysate (lal) test are broadly used for the detection of pyrogens. Not less than 0.5 ml per 1 kg and not more than 10 ml per kg of body mass determination of the initial and maximum temperature all rabbits should have initial.
The Requirement In 21 Cfr 610.13(B) May Be Waived If A Method Equivalent To The Rabbit Pyrogen Test Is.
The pyrogens, as their name suggests, refer to all the substances that cause an increase in fever, also known as pyrexia. Pyrogen test is performed to check the presence or absence of pyrogens in all aqueous parenterals. A clinical thermometer is inserted in the rectum of each rabbit to a depth of not less than 7.5 cm.
Not More Than 40 Minutes Immediately Preceding The Injection Of The Test Dose, 3.
Rabbits are used to perform the test because their body temperature increases when pyrogen is introduced by parenteral route. The same group of rabbits might be tested repeatedly every few days until they develop a tolerance to the drugs. Warming the product dissolving or dilution duration of injection:
Rabbits Used For Pyrogen Testing Are Reused For Additional Pyrogen
Record the temperature of each animal. All in vivo rabbit pyrogen tests are performed according to usp. The pyrogen test on rabbits is based on the measurement of the increase in the rabbit's temperature upon being injected with a product that could contain a contaminant of the pyrogen type.
Record The Initial Temperature Of.
As a consequence the rabbit pyrogen test (rpt) was implemented into the british pharmacopeia. After a pyrogen test in the course of which a rabbit's temperature has risen by 0.6° or more, or after a rabbit has been given a test substance that was adjudged pyrogenic, at least 2 weeks must be allowed to elapse before the animal is used again. The rabbit pyrogen test is the first standard technique fo.
