Snail, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to snail by identifying the specific allergen responsible for symptoms. It assists in confirming sensitization before immunotherapy and investigates allergic reactions to various allergens, such as insect venom or drugs. IgE antibody testing is best suited for use in patients who are suspected of having an allergy and for whom allergen identification influences medical management.
Special Instructions
Not provided.
Limitations
The presence of IgE antibodies is not always indicative of clinically relevant sensitivity; results must be interpreted in the context of clinical presentation. False positives may occur in patients with high IgE levels due to nonspecific binding. The test is not useful for determining residual sensitivity post-immunotherapy or if allergen specificity does not impact management.
