Tree Panel #3, Serum
Use
This test is useful for establishing a diagnosis of an allergy to trees in panel #3. It helps define the allergen responsible for eliciting signs and symptoms in patients and is important for confirming sensitization prior to beginning immunotherapy or investigating the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens. Testing for IgE antibodies is particularly useful for identifying allergens responsible for allergic responses and/or anaphylactic episodes.
Special Instructions
Not provided.
Limitations
False-positive results may occur in patients with markedly elevated serum IgE due to nonspecific binding. In some cases, individuals with clinically insignificant sensitivity may have measurable levels of IgE antibodies. Therefore, results must be interpreted within the clinical context. Since only one result is generated, follow-up testing is required to identify individual allergen responses within the panel.
