Helminthosporium halodes, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to Helminthosporium halodes and defining the allergen responsible for eliciting signs and symptoms. It aids in identifying allergens responsible for allergic response and/or anaphylactic episode, confirming sensitization before beginning immunotherapy, and investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
Not provided.
Limitations
Some individuals with clinically insignificant sensitivity to allergens may have measurable levels of IgE antibodies, and test results must be interpreted in the clinical context. 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.
