Soya Allergy Test London | Gly m IgE
This guide explains soya IgE testing, including the Gly m allergen components and the way soya commonly appears in processed foods. Our service is CQC-registered and diagnostic-only: we provide nurse-led venous sample collection and laboratory reporting, while diagnosis and treatment decisions remain with your GP or specialist.
Safety note
If severe breathing symptoms, throat swelling, collapse, or suspected anaphylaxis occur, call 999 immediately. Blood testing is not an emergency service.
Gly m IgE components
Gly m components are individual soya allergen proteins used in component-resolved testing. They can help characterise sensitisation patterns and support more precise interpretation.
For example, the Gly m4 component can be relevant in birch-associated cross-reactivity. Component results should always be reviewed with your reaction history by your GP or specialist.
Common in processed foods
Soya is widely used across processed foods, including some breads, sauces, spreads, ready meals, bakery items, and protein products.
Soya is a declarable allergen in the UK, so packaged foods must identify it when present. Checking labels remains important for people managing soya allergy.
Soybean Components Test
Component-level soya (soybean) testing support, including Gly m allergen context.

What are Gly m components in soya allergy?
Gly m components (such as Gly m4, Gly m5, Gly m6) are individual soya allergen proteins used in component-resolved testing to help characterise sensitisation patterns.
Where is soya commonly found in processed foods?
Soya is widely used in processed foods, including some breads, sauces, ready meals, protein products, spreads, and bakery items. Always check labels, as soya is a declarable allergen in the UK.
Can a blood test alone diagnose soya allergy?
No. Specific IgE results are supportive markers and should be interpreted with your reaction history by your GP or specialist. Our clinic provides nurse-led sample collection and laboratory reporting only.
Does soya allergy relate to birch pollen sensitisation?
In some patients, the Gly m4 component can be associated with birch pollen cross-reactivity. Interpretation should be made by your clinician using your full history.
