ADRs have been classified by Rawlins and Thompson in four types: • Type A reactions • Type B reactions that are uncommon (approximately 10% to 15%), not predictable, and occur only in susceptible individuals • Others: type C and type D reactions.

Allergic reactions are, by definition, immunologically mediated. A single drug may initiate multiple immune responses, and multiple antigenic determinants may be formed from a single drug.

Is a fishing net adequate for our purposes ? http://www.monografias.com/trabajos59/fabula-lanzador-redes/Image23883.gif
My personal opinion is that, like our fisherman here • Our fishing net is not big enough to catch all drug allergies
My personal opinion is that, like our fisherman here • AND • Our fishing net allows too many of them to escape
OR MAYBE... • We need to discover new knowledge or create a new system that captures everything.

The World Allergy Organization has recommended the use of the adjectives immediateanddelayed referring to the onset of the symptoms, as helpful in distinguishing whether the probable immunologic mechanism is antibody mediated or T-lymphocyte-mediated.

Skin Testing: Skin testing is the basic diagnostic tool, although in patients with a history of severe reactions, in vitro tests may be the recommended choice. Diagnosis tests • Skin testing is highly accurate for the identification of penicillin allergy. • Blanca M., Romano A., Torres M.J., Fernández J, et al. Update on the evaluation of hypersensitivity reactions to betalactams. Allergy 2009. 64, 183-193
Other Testing: The measurement of IL-2, IL-5, IL-13 or IFN-gammaor a combination there of might be a useful in vitro tool for detection of T-cell sensitization to drugs Diagnosis tests Lochmatter P., Beeler A., Kawabata T.T., Gerber B.O., Pichler W.
