Clinical significance:
The Peanut Allergen Test helps to assess a patient's level of risk of an allergic reaction, and may reassure patients when the risk for allergic symptoms is low or when they will most likely experience mild or localized reactions upon exposure to peanut. The test helps the health care provider identify primary, species-specific allergic sensitization, differentiate between symptoms caused by a primary allergen source and those caused by cross-reactivity, assess the level of risk for life-threatening allergic reactions, and provide clarity regarding the patient's risk of an allergic reaction to ease fears and help target effective management.
