Study Outline

In the Material Mediated Pyrogen test, a medical device is extracted in a 0.9% saline solution and injected into the marginal ear vein of each of three animals. Rectal temperatures will be recorded for each animal prior to injection and between 1 and 3 hours post-injection (at minimum 30 minute intervals). The test article will be considered negative if none of the animals has an individual temperature difference greater than or equal to 0.5°C when the baseline temperature is subtracted from the maximum temperature recorded between 1 and 3 hours post-injection. If any rabbit has an individual temperature rise greater than or equal to 0.5°C, then the sample is considered a potential pyrogen.
