Allergy Tests

Allergy tests are a way of asking your immune system what it's been reacting to. Your body produces a specific antibody called IgE when it encounters something it considers a threat, even if that "threat" is perfectly harmless pollen or a piece of shrimp. Allergy tests help us detect that response, whether through your skin or your blood. It's not a single test. It's a family of diagnostic approaches, chosen depending on your symptoms, your age, and what we suspect might be causing the problem.

Testing gives you a direction. It also helps doctors avoid over-prescribing medications and treat the exact allergen. Uncontrolled allergic rhinitis often worsens asthma. Certain food allergies can cause anaphylaxis, a severe, life-threatening reaction that needs an epinephrine injection within minutes. Testing isn't just about comfort. Sometimes it's about safety.

You may need allergy testing if you're experiencing any of the following:

• Recurring sneezing that doesn't respond to usual remedies
• Watery, itchy, or red eyes - especially in certain environments or seasons
• Skin rashes or hives that come and go without a clear cause
• Unexplained swelling of the lips, tongue, or throat
• Breathing difficulties triggered by specific foods, places, or situations
• Chronic cough, particularly in children - this may have an allergic component even without fever or cold symptoms
• Digestive symptoms like bloating or cramping after certain meals, which can sometimes point to food allergies, though other conditions need to be ruled out first

Skin Prick Test

• The most commonly performed allergy test
• Small drops of allergen extracts are applied along the forearm, spaced roughly 2 cm apart, and a lancet is used to gently prick through each drop
• Results appear within 15 to 20 minutes; a raised, reddened wheal at any site suggests sensitivity to that allergen
• Mildly uncomfortable, similar to a light scratch; children generally tolerate it well

Blood Allergy Test (Specific IgE)

• Preferred when active skin conditions like eczema make the skin prick test unreliable, or when greater diagnostic precision is needed
• Measures specific IgE antibody levels in the blood, reported in kUA/L
• Levels above 0.35 kUA/L are generally considered positive, though results are always interpreted alongside your clinical history

Patch Test

• Used when contact dermatitis is suspected, reactions to metals like nickel, cosmetic preservatives, or rubber compounds
• Adhesive patches are applied to the upper back and left in place for 48 hours
• Readings are taken at both 48 and 72 hours after removal

Food Allergy Testing

• Typically combines blood testing with a structured oral food challenge conducted under supervised conditions
• Elimination diets may also be recommended in select cases, but only with careful monitoring, as unsupervised elimination can lead to nutritional deficiencies, particularly in children

Stop antihistamines at least five days before the skin prick test, ideally seven days for long-acting ones like cetirizine or fexofenadine. Some antidepressants and heartburn medications can also suppress skin reactions, so always share your complete medication list. Don't apply creams or moisturizers to your forearms on the day of testing. Blood tests have no such restrictions.

A positive test result means your immune system recognizes that allergen. It doesn't automatically mean it's causing all your symptoms. Results always need to be read alongside your clinical history. A negative result, on the other hand, makes that allergen much less likely to be the cause, though it doesn't entirely rule it out in every case.
