Description

"Oral Allergen Challenge" test helps determine what’s triggering allergic symptoms when standard tests haven’t provided clear answers. Conducted under close medical supervision, you’ll consume specific foods or medications while being monitored for reactions. This test is especially helpful when a food or drug allergy is suspected but not confirmed. Based on the outcome, your doctor may suggest dietary changes, new treatments, or further testing to help control symptoms and manage allergies with more accuracy and confidence.

Allergy Group

Test Group Description

Allergy Group: Tests in this group pinpoint allergic sensitivities by measuring specific antibodies (like IgE) in response to common allergens. They help identify triggers such as pollen, dust mites, pet dander, and certain foods, guiding personalized allergy management plans.

Optimal Range

For All Individuals:

  • Result: Negative: No abnormalities detected.

Normal Range

For All Individuals:

  • Result: Negative: No abnormalities detected.

Results That Differ From The Norm (Direct and Indirect Causes)

Abnormal results may indicate:


  • Drug allergies (Allergic reactions triggered by specific medications)

  • Eosinophilic esophagitis (Chronic allergic inflammatory condition of the esophagus)

  • Exercise-induced anaphylaxis (Allergic reaction triggered by physical activity)

  • Food allergies

  • Insect sting allergies

  • Latex allergy

  • Oral allergy syndrome (Allergic reaction to certain raw fruits, vegetables, or nuts due to cross-reactivity with pollen proteins)

Key Reasons For Testing

  • Allergy Diagnosis Confirmation: Confirms food allergies by inducing controlled allergic reactions under medical supervision.

  • Assessment of Allergic Sensitivity: Determines reaction severity and sensitivity thresholds for specific allergens.

  • Identification of Causative Allergens: Identifies specific allergens responsible for symptoms when testing is inconclusive.

  • Evaluation of Tolerance Development: Assesses whether individuals, particularly children, have outgrown food allergies.

Important Note

Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.


Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
