Specific Inhalation Challenge
The Specific Inhalation Challenge (SIC) is defined as a diagnosis tool to assess airway responsiveness to "sensitizing" substances as opposed to nonspecific stimuli such as pharmacological agents (i.e. histamine, methacholine), cold air and exercise. Subjects are exposed to a suspected occupational agent in a controlled way under close supervision in a hospital laboratory. The specific inhalation challenges has been considered as the gold standard in confirming the diagnosis of occupational asthma.

Famous quotes containing the words specific and/or challenge:
“Patriotism is proud of a country’s virtues and eager to correct its deficiencies; it also acknowledges the legitimate patriotism of other countries, with their own specific virtues. The pride of nationalism, however, trumpets its country’s virtues and denies its deficiencies, while it is contemptuous toward the virtues of other countries. It wants to be, and proclaims itself to be, “the greatest,” but greatness is not required of a country; only goodness is.”
—Sydney J. Harris (1917–1986)
“He’s indestructible. Frankenstein’s creation is man’s challenge to the laws of life and death.”
—Edward T. Lowe, and Erle C. Kenton. Dr. Edelman (Onslow Stevens)
