What Allergy Profile 11 (Combined Shellfish/Finfish) measures
Laboratories file the Allergy Profile 11 (Combined Shellfish/Finfish) under shellfish allergy, finfish allergy and seafood sensitivity. The following sections set out how an allergy panels and profiles test of this kind is measured and read.
Allergy panels measure specific IgE to a group of related allergens in one sample — UK aeroallergens, common foods, nuts and seeds, shellfish and finfish, insects, antibiotics, or a broad screen covering both foods and inhalants. Multiplex tests such as ALEX² report several hundred allergens and components at once from a single blood draw. Profiles built around a symptom, such as allergic rhinitis or eczema, group the allergens most often relevant to that presentation.
Who considers Allergy Profile 11 (Combined Shellfish/Finfish)
- People often consider a panel if they have year-round or seasonal nasal symptoms and cannot identify the trigger.
- Those with eczema or asthma that seems to flare with food or environment frequently want a broad first look.
- Reactions to several different foods, or to restaurant meals where the ingredients were unclear, are a common reason for a food panel.
- A large multiplex screen suits people who want one comprehensive assessment rather than several visits.
- Suspected antibiotic allergy is sometimes investigated with a drug panel before a planned course of treatment.
Understanding your Allergy Profile 11 (Combined Shellfish/Finfish) results
Each allergen is reported as a class or numeric value; the higher the level, the more likely a genuine reaction, though the pattern across related allergens often matters more than any single number. Broad panels frequently show several positives that reflect cross-reactivity between similar proteins — birch pollen and apple, for example — rather than separate allergies. A report with many low positives is common in atopic people and is interpreted alongside your history rather than treated as a list of foods to avoid.
Panels indicate sensitisation across many allergens at once, so false positives are expected; results should be reviewed with an allergy clinician before any dietary or lifestyle change.
Related areas of testing at Wimpole Street: allergy — specific IgE, food intolerance and digestive sensitivity, inflammation markers, wellness and biochemistry profiles.
