Food Allergy Profile with Reflexes
Also known as: ImmunoCAP®
Use
This panel measures immunoglobulin E (IgE) antibodies in the blood in response to common food allergens, helping in determining sensitization and guiding potential allergy diagnosis. Reflex testing to egg, milk, or peanut component panels is automatically performed when IgE levels are above threshold, increasing specificity of results. Results must be interpreted alongside clinical history and other diagnostic methods by a healthcare provider.
Special Instructions
Reflex testing to component panels for egg, milk, or peanut is performed automatically at no additional cost when specific IgE thresholds are met. No special patient preparation is required. Sample collection is via serum at Quest Diagnostics or via Quest Mobile where available. Results may be released in as few as 1 business day.
Limitations
Presence of IgE antibodies alone does not confirm clinical allergy or reaction severity; results must be integrated with clinical history and other diagnostic tests such as skin-prick tests. Age eligibility applies (10–100 years); certain patient populations may require additional counselling.
