We offer two main types of allergy tests. Skin prick tests introduce tiny amounts of allergens into the skin surface and produce results within 20 minutes, making them ideal for environmental allergens. Blood tests measuring specific IgE antibodies test for a broad panel of allergens from a single blood sample and are useful when skin testing is not possible, such as during antihistamine use or with widespread skin conditions. Your doctor will recommend the most appropriate test based on your symptoms and medical history.

For skin prick testing, you must stop antihistamines five to seven days before testing as they suppress skin reactions and can produce false negative results. Common antihistamines include cetirizine, loratadine, and fexofenadine. Continue other medications unless your doctor advises otherwise. Blood-based IgE tests are not affected by antihistamines, so no medication changes are needed. Bring a list of suspected triggers and note when and where your symptoms are worst to help guide testing decisions.

Yes, skin prick testing is very safe and has been used for decades in allergy diagnosis. The test introduces only tiny amounts of allergen into the skin surface, producing small localized reactions (red bumps) at positive test sites. Systemic allergic reactions are extremely rare. All patients are monitored throughout testing, and our clinic is equipped with emergency medications and resuscitation equipment as a precaution. The test is well-tolerated by both adults and children and causes only mild, temporary discomfort.

Skin prick tests have high sensitivity (around 85 to 90 percent) for environmental allergies such as dust mites, pollen, and pet dander. Blood IgE tests are equally accurate and particularly useful for food allergy evaluation. However, a positive test indicates sensitization, which does not always correlate with clinical symptoms. This is why results must be interpreted alongside your clinical history by an experienced specialist. False positives and negatives can occur, and sometimes additional testing or oral food challenges are needed for definitive diagnosis.

Immunotherapy, also known as desensitization, gradually trains your immune system to tolerate specific allergens. It is available as subcutaneous injections (allergy shots) given regularly over three to five years, or as sublingual tablets or drops placed under the tongue daily. Immunotherapy is the only treatment that modifies the underlying allergic disease rather than just controlling symptoms. It can provide lasting relief even after treatment is completed and may prevent the development of new allergies and asthma in children.

Yes, allergy testing is safe and appropriate for children of all ages. Skin prick testing can be performed on children as young as six months, though it is more commonly done from age two onwards. Blood IgE testing has no age restrictions. Identifying allergies early in children is particularly valuable because it allows targeted avoidance strategies, appropriate medication, and consideration of immunotherapy that can modify the allergic march, preventing progression from eczema and food allergies to allergic rhinitis and asthma.

The most common allergens in Dubai include house dust mites, which thrive in the humid indoor environment, mold spores from air conditioning systems, pet dander from cats and dogs, cockroach allergens, and seasonal pollens from date palms and grasses. Food allergens including nuts, shellfish, dairy, and wheat are also prevalent. The unique combination of desert climate, air conditioning culture, and diverse expatriate population means allergen exposure patterns in Dubai differ from other regions, making local testing expertise important.

An allergy involves an immune system response mediated by IgE antibodies, producing symptoms that can range from mild (sneezing, hives) to severe (anaphylaxis). An intolerance does not involve the immune system and typically causes digestive symptoms. For example, lactose intolerance is caused by enzyme deficiency, not an immune reaction to milk protein. IgE allergy testing identifies true allergies but not intolerances. The distinction is important because allergies can cause potentially dangerous reactions, while intolerances, though uncomfortable, are generally not life-threatening.
