Lentil, IgE, Serum
Use
The Lentil IgE test is useful for establishing a diagnosis of an allergy to lentil by identifying the specific allergens responsible for allergic responses and symptoms. This test can confirm sensitization before initiating immunotherapy and can be used to investigate specific allergic reactions to insect venoms or chemical allergens. It is important for identifying allergens responsible for allergic responses or anaphylactic episodes. Testing for IgE antibodies is not useful for patients who previously received immunotherapy for residual sensitivity or when medical management does not depend on allergen identification.
Special Instructions
For optimal results, it is recommended to centrifuge and aliquot serum into a plastic vial immediately after collection. If not ordering electronically, complete and send an Allergen Test Request (T236) form with the specimen. Sample should be transported refrigerated or frozen if not immediately processed.
Limitations
IgE antibody testing may not always correlate with clinical symptoms. False positives may occur in patients with very high levels of serum IgE (>2500 kU/L) due to nonspecific binding. These results need to be interpreted within the clinical context, as some patients with a mild sensitivity to allergens may still have measurable levels of IgE antibodies, and these specific antibodies may not indicate clinical sensitivity.
