Allergen, Food, Spinach
Also known as: SPINACH
Use
The Allergen, Food, Spinach test is utilized to measure allergen-specific IgE levels to spinach. It is intended for the evaluation of individuals with suspected allergic reactions to spinach, aiding in the diagnosis of spinach allergy. The test measures the concentration of allergen-specific IgE antibodies to determine the likelihood of an IgE-mediated allergic reaction.
Special Instructions
Multiple patient encounters should be avoided for accurate results. Specimen collection requires serum to be separated from cells as soon as possible or within 2 hours of collection.
Limitations
Results of 0.10-0.34 kU/L have undetermined clinical relevance and are intended for specialist use. Although increasing IgE concentrations generally indicate increasing allergic sensitivity, these levels may not correlate precisely with the clinical response as observed in skin testing or exposure to the allergen. A negative test result can’t definitively rule out clinical allergy or anaphylaxis. It's important to correlate laboratory results with clinical history and in vivo reactivity.
