Your body bodyweight and temperature circumstances of your rabbit tend to be taken and recorded just before and soon after injection in the test compound. A rise in the body temperature with the test rabbit just after certain measured time intervals is indicative of the favourable test consequence; and this implies the test sample contained pyrogens – which brought about the rise in the body temperature with the animal.
