Allergen, Food, Asparagus IgE
Also known as: ASPARAGUS
Use
The Allergen, Food, Asparagus IgE test is used to measure the concentration of IgE antibodies specific to asparagus allergens in the patient's serum. It is intended to aid in the diagnosis of asparagus allergies in individuals exhibiting allergic symptoms. The test measures IgE levels using a fluorescent enzyme immunoassay, helping clinicians determine an individual's sensitivity to asparagus and assisting in allergy management.
Special Instructions
Multiple patient encounters should be avoided. After serum separation, it should be transferred to an ARUP Standard Transport Tube for transport. For those ordering multiple allergen tests, refer to the Allergen Specimen Collection Instructions available on the ARUP Laboratories website.
Limitations
This test has not been cleared or approved by the FDA, but is performed in a CLIA-certified lab for clinical purposes. The results may not directly correlate with clinical allergy severity or skin test reactions. A negative result does not exclude the possibility of clinical allergy or anaphylaxis to asparagus. The test is intended for specialist interpretation, especially for results between 0.10-0.34 kU/L, where clinical relevance is undetermined. Correlation with patient history and in vivo reactivity is crucial.
