Penicillium chrysogenum, IgE, Serum
Use
This test is useful for establishing a diagnosis of an allergy to Penicillium chrysogenum. It is helpful in defining the allergen responsible for eliciting signs and symptoms and can be used to identify allergens responsible for allergic responses or anaphylactic episodes. Additionally, it can confirm sensitization prior to beginning immunotherapy and investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
Not provided.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists, or in patients where medical management does not depend upon allergen identification. False-positive results can occur in patients with elevated serum IgE due to nonspecific binding. Test results must be interpreted within the clinical context as individuals with clinically insignificant sensitivity may still show measurable IgE levels.
