Allergen, Food, Sesame Seed Component rSes i 1
Also known as: SESAME COM
Use
This test is used to quantify specific IgE levels for the allergen sesame seed component rSes i 1 using the ImmunoCAP Fluorescent Enzyme Immunoassay. These quantifications are beneficial for diagnosing potential IgE-mediated allergic responses to sesame seeds. Allergen results of 0.10-0.34 kU/L have clinical relevance which remains undetermined and should be utilized by specialists. The presence of increasing concentrations of allergen-specific IgE may not precisely correlate with the severity of clinical reactions or predict allergy challenge test outcomes.
Special Instructions
Multiple patient encounters should be avoided while preparing for the collection of this test. It is crucial to follow the specific specimen preparation and storage instructions to ensure the integrity of the test results. Refer to the 'Allergen Specimen Collection Instructions' for multiple allergen orders at www.aruplab.com/testing/resources/specimen.
Limitations
The results of the allergen-specific IgE test do not always correlate directly with the severity of clinical symptoms or with results from other methods such as skin testing. A negative result does not rule out the possibility of a clinical allergy or anaphylaxis to the sesame allergen. Interpretation of laboratory results should be combined with clinical evaluations, including patient history and all in vivo reactivity tests to specific allergens.
