Peanut Allergy Test
Allergy
This blood test measures IgE antibodies against peanut proteins to determine if you have a peanut allergy and estimate sensitivity.
VAT-exempt medical service
Peanut allergy is one of the most common and potentially severe food allergies. Even trace amounts can trigger reactions ranging from mild hives to life-threatening anaphylaxis in highly sensitive individuals. This IgE blood test detects antibodies against peanut proteins, helping to confirm a diagnosis, estimate the degree of sensitivity, and guide safe management of peanut exposure in daily life.
This test is recommended if you or your child have experienced allergic symptoms after eating peanuts or peanut-containing foods, if you are unsure whether you react to peanuts, if you have a family history of food allergies, or if you need a confirmed diagnosis before introducing or eliminating peanuts from the diet.
What a high value can mean
High IgE levels indicate a likely peanut allergy. The level can also suggest the degree of sensitivity. Even low exposures may cause a reaction in highly sensitised individuals. An action plan should be discussed with an allergist.
What a low value can mean
Low or negative IgE levels reduce the likelihood of a peanut allergy but do not completely rule it out. Results must always be interpreted in combination with symptoms and medical history.

Peanut allergy can cause anaphylaxis, a life-threatening reaction involving breathing difficulties, a drop in blood pressure, and loss of consciousness. People with confirmed peanut allergy should carry an adrenaline auto-injector.
About 20% of children with peanut allergy outgrow it. Regular follow-up testing and supervised oral food challenges can help determine if the allergy has resolved.
The IgE blood test is a strong indicator, but diagnosis should always be made in consultation with an allergist, who may also consider your history, symptoms, and possibly an oral food challenge.
