Allergen, Food, Mandarin IgE
Also known as: MANDARIN
Use
This test measures the specific IgE antibodies to mandarin allergens, which are part of the food allergen panel. IgE testing is used to help diagnose allergic disorders and determine if a patient has an immune response to specific foreign substances. The increase in allergen-specific IgE concentrations may indicate an allergic sensitization, but these levels may not always correlate with clinical symptoms. A comprehensive allergy assessment, including patient history and clinical symptoms, is necessary for accurate diagnosis and management of allergies.
Special Instructions
Ensure that serum is separated from cells as soon as possible, within two hours of collection. Transfer the serum into an ARUP Standard Transport Tube. For patient preparation and collection, consult the 'Allergen Specimen Collection Instructions' available at the ARUP website. The test is performed continuously from Sunday to Saturday, and it is important to verify specimen integrity, avoiding hemolyzed, icteric, or lipemic samples.
Limitations
The detection of specific IgE antibodies does not in itself confirm an allergy, and a negative test does not rule out the presence of an allergy or the possibility of anaphylaxis. Allergen test results within the range of 0.10-0.34 kU/L are primarily for specialist use due to their uncertain clinical relevance. These concentrations might not always reflect the severity of clinical response. It is critical to correlate laboratory results with clinical history and in vivo reactions to allergens. Additionally, the test was developed by ARUP Laboratories and has not been cleared by the FDA; it was performed in a CLIA-certified laboratory for clinical purposes.
