What is an Allergy?
An allergy is an exaggerated immune system response to a foreign substance (allergen) that is typically harmless to most people. In allergic individuals, the body produces Immunoglobulin E (IgE) antibodies that trigger the release of histamine and other chemicals, leading to symptoms such as sneezing, itching, rashes, or digestive issues.
Common allergens include tree and grass pollen, mould spores, dust mites, cockroach droppings, pet dander, certain foods, and airborne pollutants.
Understanding Allergies and Triggers
Allergies can develop at any age, though many begin in childhood. Genetic predisposition, environmental factors, and immune system status play significant roles. Exposure to allergens during periods of weakened immunity—such as after an illness or during pregnancy—may increase susceptibility.
Airborne particles from smoke, exhaust fumes, aerosol sprays, and industrial pollution can exacerbate symptoms. Perennial allergic rhinitis, which occurs year-round, is often triggered by indoor allergens like house dust mites, animal dander, and mould spores.
Food Allergy vs. Food Intolerance
It is crucial to distinguish between a food allergy (an immune-mediated reaction) and food intolerance (a digestive or metabolic issue). Food allergies involve IgE antibodies and can cause severe reactions, including anaphylaxis. Food intolerance, such as lactose intolerance, does not involve the immune system and typically causes digestive discomfort.
About 90% of food allergies are triggered by cow's milk, soy, eggs, wheat, peanuts, tree nuts, fish, and shellfish. The most common food allergy in adults is to crustaceans (shrimp, crab, lobster).
The Test: Food Intolerance, Drug Sensitivity & Air Pollution Panel
This comprehensive blood test measures specific IgE antibodies against a wide range of food allergens, drug sensitivities, and environmental pollutants. Using advanced immunoassay techniques (e.g., ELISA, microarray), the test identifies potential triggers for allergic reactions.
The panel includes common food allergens (dairy, eggs, nuts, seafood), drug sensitivities (penicillin, sulfa drugs), and airborne pollutants (dust mites, pollen, mould). Results help guide personalized avoidance strategies and treatment plans.
Why Allergy Testing is Performed
Allergy testing is essential for diagnosing allergic conditions and preventing severe complications. The World Allergy Organization estimates that asthma, an allergic disease, causes approximately 250,000 deaths annually—many of which are preventable with proper allergy management.
Testing helps identify specific triggers, allowing patients to avoid allergens and reduce reliance on medications. It also aids in distinguishing between allergies and other conditions with similar symptoms.
Interpreting Results
Diagnosing food allergies requires careful correlation of test results with clinical history. A positive specific IgE test indicates sensitization, but not necessarily a clinical allergy. A negative test is more useful for ruling out an allergy.
Your allergist will interpret the results in the context of your symptoms, dietary habits, and exposure history. They may recommend an elimination diet or oral food challenge for confirmation.
