Allergen, Food, Chocolate

Also known as: CHOCOLATE

Clinical Use

Use

This test is used to measure the concentration of allergen-specific IgE antibodies to chocolate in the blood, which can indicate the likelihood of an allergy and the potential for clinical reactions upon exposure to chocolate. The test results help in assessing the presence of IgE-mediated allergic reactions, guiding management strategies, and determining the need for further allergy testing or avoidance measures. However, the IgE levels may not directly correlate with clinical reactions or skin test results, making clinical correlation essential.

Special Instructions

Not provided.

Limitations

The test measures allergen-specific IgE concentrations, which may not correlate perfectly with the degree of clinical response or skin test results when challenged with a specific allergen. A negative result does not rule out clinical allergy or anaphylaxis. Levels in the range of 0.10-0.34 kU/L require specialist interpretation as their clinical significance is undetermined. The interpretation of results must be related to clinical history and in vivo reactivity to specific allergens.
