Overview of the Sesame Ige Test
The Sesame IgE blood test measures Immunoglobulin E antibodies directed against sesame proteins, supporting assessment of IgE-mediated sesame allergy.
The test assesses 1 allergy biomarker: Sesame seed IgE level.
Sesame is a recognised food allergen and can be found in sesame seeds, tahini, bakery products, sauces, hummus and many processed foods.
People with IgE-mediated sesame allergy produce allergen-specific antibodies against proteins within sesame.
After exposure, these antibodies can trigger rapid allergic reactions.
Symptoms can include hives, itching, swelling, vomiting, wheezing or, in severe cases, anaphylaxis.
A specific IgE blood result identifies sensitisation, which is not always identical to clinical allergy.
Some people have measurable Sesame IgE but can eat sesame without symptoms.
The result therefore needs to be interpreted alongside the person's actual reaction history.
Higher specific IgE concentrations can increase the likelihood that sensitisation is clinically important, but they do not reliably predict the severity of a future reaction.
Sesame IgE testing is different from testing for food intolerance.
Food intolerance does not involve the same immediate IgE-mediated immune mechanism.
Where the history remains unclear, an allergy specialist may consider sesame component testing or a medically supervised oral food challenge.
What Does the Sesame Ige Test Check?
The test measures IgE antibodies directed against sesame proteins. This test measures 1 biomarker.
Sesame seed IgE level
Measures sesame-specific IgE antibodies, supporting assessment of immediate IgE-mediated sesame sensitisation when interpreted alongside clinical reaction history.
Who May Benefit From the Sesame Ige Test?
Testing can be useful where symptoms occur rapidly after sesame exposure or sesame is suspected as a food-allergy trigger.
People who develop hives after eating sesame - Immediate skin reactions can be consistent with IgE-mediated allergy.
People with lip, tongue or facial swelling after sesame exposure - Angioedema can occur during food-allergic reactions.
People who develop wheezing or breathing symptoms after sesame - Respiratory symptoms require careful allergy assessment.
People with rapid vomiting or abdominal symptoms after sesame-containing food - Gastrointestinal symptoms can occur during systemic allergic reactions.
People who react to tahini or sesame-containing foods - A reproducible exposure pattern increases the clinical relevance of testing.
People with other food allergies - Individual Sesame IgE testing can help clarify whether sesame is an additional trigger.
Children with suspected sesame allergy - Sesame is an important allergen in paediatric allergy assessment.
People with a previous positive sesame test requiring reassessment - Repeat testing can occasionally contribute to allergy follow-up.
How to Prepare
You do not need to expose yourself to sesame immediately before testing.
A blood specific-IgE measurement can be performed without deliberate allergen exposure.
Symptoms and Reasons to Consider the Sesame Ige Test
IgE-mediated sesame reactions generally occur within minutes to a few hours after exposure.
Hives or widespread itching - Urticaria is a common immediate allergic symptom.
Lip or facial swelling - Angioedema can occur following sesame exposure.
Throat tightness - This can indicate a potentially serious allergic reaction.
Wheezing or breathing difficulty - Respiratory involvement can occur during systemic allergy.
Vomiting or abdominal pain shortly after exposure - Food allergy can cause rapid gastrointestinal symptoms.
Dizziness or collapse after eating sesame - These can occur during severe anaphylaxis.
Difficulty breathing, throat swelling, collapse or other symptoms of anaphylaxis require emergency medical treatment.
The specific IgE concentration cannot predict how severe a future allergic reaction will be.

When Will I Receive My Results?
The current live London Blood Tests page lists a turnaround of approximately 1 day after laboratory receipt for Sesame IgE.
The sample undergoes allergen-specific IgE measurement, quality-control procedures and result authorisation.
Understanding Your Results
A negative or very low result means significant sesame-specific IgE was not detected by the laboratory assay.
This makes IgE-mediated sesame sensitisation less likely but cannot exclude every food reaction.
A positive result demonstrates sensitisation to sesame proteins.
It does not automatically prove that eating sesame will cause symptoms.
The concentration can be considered alongside the person's reaction history, age and other allergy findings.
Someone who regularly eats sesame without symptoms may have laboratory sensitisation without clinically significant allergy.
Where the history is strongly suggestive despite an uncertain blood result, specialist allergy assessment can be appropriate.
Why Book With London Blood Tests?
London Blood Tests provides private individual Sesame IgE testing for focused food-allergy assessment.
Measures sesame-specific IgE - The test directly assesses allergic sensitisation to sesame proteins.
Useful for immediate food reactions - Results can support investigation where symptoms follow sesame exposure rapidly.
Suitable for adults and children - Specific IgE testing can be used across age groups.
No food challenge is required for the blood test - Deliberate sesame exposure is unnecessary.
Antihistamines generally do not affect the result - Blood testing can usually be performed while taking antihistamines.
Can complement broader allergy testing - Sesame components and other individual allergens can be added where appropriate.
Rapid laboratory turnaround - Results are expected approximately 1 day after laboratory receipt.
Clear pricing - The Sesame IgE test costs £55.
