Irritant Reactions
Initial immune response to allergen, no symptoms manifested from this response, latent interval required before sensitivity can be expressed, variable # of exposures for sensitization of individual: * some people are easily sensitized with single exposure.
Sensitizing Dose of Contact Dermatitis
Name that condition: TYPE IV OR DELAYED, CAN RESULT FROM EXPOSURE TO CHEMICALS AND RUBBER, USUALLY APPEARS AS A RASH SEVERAL HOURS OR EVEN DAYS AFTER EXPOSURE
Allergic Contact Dermatitis
exposure to allergen in a sensitized person, results in manifestation of allergic symptoms, challenge occurs with much lower allergen concentration, severity of symptoms dependent on extent of sensitization, some do not react, or only slightly react, to multiple challenges —- leads to diagnosis difficulties.
