Gerbil Epithelium, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to gerbil epithelium by identifying specific IgE antibodies responsible for allergic responses and symptoms. It can confirm sensitization prior to beginning immunotherapy and investigate the specificity of reactions to allergens, drugs, or chemicals. Testing for IgE antibodies supports assessing sensitivity to allergens in clinical contexts where allergic diseases may manifest, such as eczema and respiratory diseases in various age groups.
Special Instructions
Ordering should include the correct allergen test form if ordering manually. The test requires a serum sample that should be centrifuged and aliquoted into a plastic vial for submission. Ensure proper handling to avoid causes of rejection like gross hemolysis or lipemia.
Limitations
IgE antibody testing is not useful in patients previously treated with immunotherapy to check for residual sensitivity. False-positive results may occur in patients with high serum IgE levels due to nonspecific binding. Results must be interpreted within the clinical context, considering factors like age, history of allergen exposure, and seasonal trends.
