Overview of the Nut Panel Test
The Nut Panel is a broad allergy blood test measuring specific IgE antibodies to multiple nuts and sesame alongside overall Immunoglobulin E.
The profile assesses 14 allergy biomarkers.
It includes Almond, Brazil nut, Cashew nut, Chestnut, Coconut, Hazelnut, Macadamia nut, Peanut, Pecan nut, Pine nut, Pistachio, Sesame seed and Walnut-related testing together with Immunoglobulin E.
IgE-mediated food allergy occurs when the immune system produces specific antibodies against proteins within a food.
Exposure can then trigger symptoms including itching, hives, swelling, vomiting, wheezing or anaphylaxis.
One advantage of a multi-allergen panel is that several possible triggers can be evaluated from one blood collection.
This can be useful where reactions occur after mixed foods or where it is unclear which nut or seed is responsible.
A positive specific IgE result identifies sensitisation.
Sensitisation does not automatically mean that eating the relevant food will cause a clinical reaction.
Some people have detectable antibodies because of cross-reactivity with pollen or related proteins while tolerating the food normally.
The concentration should therefore be interpreted alongside actual reaction history.
Specific IgE values also do not reliably predict the severity of a future reaction.
Where individual results need further clarification, allergen-component testing can sometimes provide more detailed information.
Peanut, Hazelnut and selected other allergens have component-resolved tests capable of distinguishing sensitisation to different proteins.
The panel should support targeted allergy assessment rather than unnecessary avoidance of every nut.
What Does the Nut Panel Contain?
The Nut Panel assesses specific IgE responses to thirteen nut and seed allergens together with Immunoglobulin E. This test measures 14 biomarkers.
Almond IgE level - Measures IgE antibodies directed against Almond proteins.
Brazil nut IgE level - Measures IgE sensitisation to Brazil nut proteins.
Cashew nut IgE level - Measures IgE antibodies associated with Cashew sensitisation.
Chestnut IgE level - Measures IgE antibodies directed against Chestnut proteins.
Coconut IgE level - Measures specific IgE associated with Coconut sensitisation.
Hazelnut IgE level - Measures antibodies against Hazelnut proteins and can be followed by component testing where needed.
Macadamia nut IgE level - Measures specific IgE associated with Macadamia nut sensitisation.
Peanut IgE level - Measures IgE antibodies against Peanut proteins.
Pecan nut IgE level - Measures IgE sensitisation to Pecan nut proteins.
Pine nut - pignoles - Assesses IgE sensitisation associated with Pine nut.
Pistachio IgE level - Measures IgE antibodies directed against Pistachio proteins.
Sesame seed IgE level - Measures specific IgE associated with Sesame sensitisation.
Walnut IgE level - Measures IgE antibodies against Walnut proteins.
Immunoglobulin E - Measures total circulating IgE, providing general allergy-related immune context but not identifying a specific allergen by itself.
Who May Benefit From the Nut Panel Test?
The panel can be useful where several nuts or seeds are possible triggers.
People who have reacted to mixed nuts - Testing several allergens can help identify which individual foods may be involved.
People with hives or swelling after nut-containing foods - These are common manifestations of IgE-mediated allergy.
People with several suspected nut allergies - A panel can reduce the need to request each allergen separately.
People with uncertain reactions to Peanut and tree nuts - Peanut and tree-nut allergies can occur independently.
People with suspected Sesame allergy - Sesame is included alongside the nut allergens.
Children undergoing broad food-allergy assessment - Specific IgE testing avoids deliberate food exposure.
People with existing allergy who want individual sensitisation patterns clarified - Results can guide specialist follow-up.
People considering targeted component testing - The panel can identify which allergens may warrant more detailed investigation.
How to Prepare
There is no need to expose yourself to suspected allergens before blood testing.
The laboratory result is most clinically useful when interpreted with a detailed food-reaction history.
Symptoms and Reasons to Consider the Nut Panel Test
IgE-mediated food-allergic symptoms typically develop rapidly after eating the trigger food.
Hives or widespread itching - Immediate skin reactions can occur.
Swelling of the lips, face or tongue - Angioedema can accompany food allergy.
Throat tightness - This can indicate a potentially serious allergic reaction.
Wheezing or breathing difficulty - Respiratory involvement can occur during anaphylaxis.
Vomiting or abdominal pain shortly after eating nuts or sesame - Gastrointestinal symptoms can occur.
Repeated reactions to mixed nut products - A broad panel can help separate possible triggers.
An uncertain previous allergy result - Repeat or broader specific IgE testing can provide additional information.
Breathing difficulty, throat swelling, collapse or rapidly progressive symptoms after food exposure can represent anaphylaxis and require emergency treatment.
Specific IgE concentrations cannot predict exactly how severe a future reaction will be.

When Will I Receive My Results?
The current London Blood Tests page lists results as available approximately 1 day after laboratory receipt.
Allergen-specific IgE measurements undergo laboratory quality-control and result authorisation.
Component-resolved allergy testing, if subsequently added, can have a different turnaround.
Understanding Your Results
A negative specific IgE result means no significant sensitisation to that allergen was detected according to the assay.
This makes IgE-mediated allergy less likely but does not completely exclude it.
A positive result demonstrates sensitisation.
Clinical allergy is more likely when a positive result corresponds closely with a reproducible reaction after eating that food.
Low-level results can sometimes occur through cross-reactivity.
The strength of an IgE result does not reliably predict the severity of a future reaction.
Total Immunoglobulin E provides general immune context but cannot identify a specific food allergy.
Where uncertainty remains, component testing or specialist-supervised food challenge may be considered.
Why Book With London Blood Tests?
London Blood Tests provides private multi-allergen Nut Panel testing for targeted food-allergy assessment.
Measures 14 allergy biomarkers - Multiple nuts, Sesame and overall IgE are assessed together.
Includes Peanut and major tree nuts - Common clinically important allergens are covered.
Includes Sesame seed - Sesame allergy can occur independently of nut allergy.
No deliberate allergen exposure is required - Testing uses a blood sample.
Antihistamines generally do not affect the test - Blood IgE testing remains possible while taking them.
Can guide component testing - More detailed allergen proteins can be assessed where appropriate.
Fast current turnaround - Results are listed approximately 1 day after laboratory receipt.
Clear pricing - The Nut Panel costs £530.
