Allergen, Weed Panel #4 (WEED4)
Test Code: ALWD4SO
Synonyms/Keywords
​Ref Lab Code: 81885, IgE Antibodies, Multi-Allergen,  Includes: Giant Ragweed, Short Ragweed, Western Ragweed  
Useful For
Testing for IgE antibodies may be useful to establish the diagnosis of an allergic disease and to define the allergens responsible for eliciting signs and symptoms.
 
Testing also may be useful to identify allergens which may be responsible for allergic disease and /or anaphylactic episode, to confirm sensitization to particular allergens prior to beginning immunotherapy, and to investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.

Interpretation
Detection of IgE antibodies in serum (Class 1 or greater) indicates an increased likelihood of allergic disease as opposed to other etiologies and defines the allergens that may be responsible for eliciting signs and symptoms.
 
The level of IgE antibodies in serum varies directly with the concentration of IgE antibodies expressed as a class score or kU/L.
