Grass Panel # 3, Serum
Use
The Grass Panel #3 is useful for establishing a diagnosis of allergy to cultivated rye, rye, sweet vernal, timothy, and velvet leaf. It helps in defining the allergen responsible for eliciting signs and symptoms, such as allergic responses and anaphylactic episodes. The panel can confirm sensitization before beginning immunotherapy and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. However, testing IgE antibodies is not useful for patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or when medical management does not depend on identification of allergen specificity.
Special Instructions
Not provided.
Limitations
This test does not differentiate individual allergen responses. False-positive results for IgE antibodies may occur in patients with markedly elevated serum IgE (>2500 kU/L) due to nonspecific binding to allergen solid phases. Individuals with clinically insignificant sensitivity may still have measurable IgE antibody levels in serum, so test results must be interpreted in clinical context.
