Latex Allergy Test London | Hev b IgE
This guide explains latex IgE testing, including latex-fruit syndrome cross-reactivity and the Hev b allergen components. 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.
Latex-fruit syndrome (banana, avocado, kiwi)
Some people sensitised to natural rubber latex may also react to certain plant foods due to shared protein structures. This pattern is known as latex-fruit syndrome and commonly involves banana, avocado, and kiwi.
Cross-reactivity is not universal, and findings should be interpreted with your symptom history by your GP or specialist.
Hev b components
Hev b components are individual latex allergen proteins used in component-resolved testing. They can help characterise sensitisation patterns and support more precise clinical interpretation.
Component results should always be reviewed alongside exposure history and reaction pattern, rather than used in isolation.

Component-level latex testing support, including Hev b allergen context.

What is latex-fruit syndrome?
Latex-fruit syndrome describes cross-reactivity between natural rubber latex proteins and certain plant foods. Commonly associated foods include banana, avocado, and kiwi.
What are Hev b components?
Hev b components are individual natural rubber latex allergen proteins (such as Hev b1, Hev b3, Hev b5, Hev b6) used in component-resolved testing to help characterise sensitisation patterns.
Can a blood test alone diagnose latex allergy?
No. Specific IgE findings are supportive markers and should be interpreted with your reaction history by your GP or specialist. Our clinic provides nurse-led blood sample collection and laboratory reporting only.
What if I have a severe reaction to latex?
If severe breathing difficulty, throat swelling, collapse, or suspected anaphylaxis occurs, call 999 immediately. Blood testing is not an emergency service.
