Allergen, Food, Rice
Also known as: RICE
Use
This test is used to detect allergen-specific IgE antibodies to rice using a quantitative ImmunoCAP Fluorescent Enzyme Immunoassay. It assists in identifying patients with rice allergies and determining the likelihood of an IgE-mediated allergic reaction. Results should be interpreted in the context of the clinical history, as the presence of IgE antibodies may not correlate with clinical symptoms or skin test results. A negative test result does not rule out the possibility of a clinical allergy or anaphylaxis.
Special Instructions
Multiple patient encounters should be avoided when collecting specimens. Follow the specimen collection instructions carefully to ensure adequate volume for allergen testing. For multiple allergen orders, refer to the provided 'Allergen Specimen Collection Instructions' on the website.
Limitations
Allergen results indicating levels from 0.10-0.34 kU/L are meant for specialist assessment as the clinical relevance at these levels is not determined. The test measures specific IgE concentrations that may not correspond with the degree of clinical reaction or skin test outcomes. Proper correlation with clinical history and in vivo reactivity to specific allergens is necessary for accurate diagnosis.
