Allergen, Food, Coffee
Also known as: COFFEE
Use
This test is used to measure allergen-specific IgE levels in patients suspected of having an allergy to coffee. The concentration of allergen-specific IgE can provide insight but may not directly correlate with the severity of the clinical response or skin testing results. Interpretation of results must be made in the context of clinical history and observed reactivity to coffee allergens. This test helps allergy specialists assess the likelihood of IgE-mediated reactions, although results within certain ranges require specialist interpretation due to undetermined clinical relevance.
Special Instructions
Serum must be separated from cells as soon as possible or within 2 hours of collection and transferred to an ARUP Standard Transport Tube. For multiple allergen orders, refer to 'Allergen Specimen Collection Instructions'.
Limitations
Allergen results within the range of 0.10-0.34 kU/L have undetermined clinical relevance and should be interpreted by a specialist. Concentrations of allergen-specific IgE identified in this test may not directly correlate with the clinical response or in vivo skin test results upon exposure to the specific allergen. A negative result does not rule out the possibility of a clinical allergy or anaphylactic reaction upon exposure to coffee allergens.
