Weed Panel # 1, Serum

Useful For Suggests clinical disorders or settings where the test may be helpful

Establishing a diagnosis of an allergy to English plantain, lamb's quarters, mugwort, Russian thistle, and short ragweed allergen


Defining the allergen responsible for eliciting signs and symptoms


Identifying allergens:

-Responsible for allergic disease and/or anaphylactic episode

-To confirm sensitization prior to beginning immunotherapy


Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients in whom the medical management does not depend upon identification of allergen specificity.


This multi-allergen IgE antibody panel, combined with measurement of IgE in serum, is an appropriate first-order test for allergic disease.


It requires less specimen volume and less cost for ruling out allergic response; however, individual (single) allergen responses cannot be identified. In cases of a positive test, follow-up testing must be performed to differentiate between individual allergens in the panel.


Note: Only one result is generated for each panel.
