Coffee
Use
This test measures the specific IgE antibodies to coffee, which helps in the diagnosis of allergic reactions to coffee. The presence of IgE antibodies suggests a sensitization to coffee and can be indicative of an allergic response. The results can aid healthcare providers in determining potential allergenic triggers for patients experiencing allergic symptoms.
Special Instructions
Room temperature storage of the sample is permitted for up to 14 days. Refrigeration and freezing are also acceptable; the former for 14 days and the latter for up to 3 months, with the sample remaining stable through three freeze/thaw cycles. A minimum volume of 0.2 mL serum is required for this test, ideally collected in a red-top tube or gel-barrier tube.
Limitations
This test is designed specifically for the detection of coffee-specific IgE antibodies and should not be used as a sole diagnostic tool for coffee allergies. False positives are possible, and clinical correlation with patient history and other diagnostic findings is necessary. The performance characteristics of this test have not been cleared or approved by the U.S. Food and Drug Administration. Results should be interpreted in the context of all available clinical data and additional confirmatory testing may be needed for accurate diagnosis.
