“Do I really have an allergy? If yes, what am I allergic to, and can it be treated?” These are the most common questions patients ask. Guessing your triggers, or taking anti-allergy tablets again and again, rarely solves the problem. Proper allergy testing gives clear answers. In this video, Dr. Dipak Viradia, Chest Physician & Intensivist, explains how allergy is confirmed and treated.

Step 1: Is It Really Allergy?

Not every sneeze, cough or rash is an allergy. Similar symptoms can be caused by viral infections, sinus problems, nasal polyps, reflux, asthma, TB or non-allergic rhinitis. A doctor first takes a detailed history: when symptoms occur, in which season, where (home, work, outdoors), what makes them worse, and whether family members have allergy or asthma. This, along with an examination, shows whether allergy is likely.

Step 2: What Are You Allergic To? Allergy Tests

Skin prick test. Tiny drops of common allergens, such as dust mites, pollen, mould, pet dander and cockroach, are placed on the forearm, and the skin is gently pricked. If you are allergic to a substance, a small itchy bump appears within about 15–20 minutes. It is quick, safe and gives results in the same visit.

Allergy blood test (specific IgE). A blood sample is tested for antibodies against specific allergens. This is useful when skin testing isn’t suitable, for example in people with widespread skin disease, those who cannot stop certain medicines, or young children.

Lung function test (spirometry / PFT). If you have cough, wheezing or breathlessness, this test checks whether the allergy has affected your lungs and whether asthma is present.

Other tests when needed. Blood counts (such as eosinophils), total IgE, or a chest X-ray may be advised in some cases.

Before testing: some anti-allergy tablets can affect skin test results. Tell your doctor about all your medicines. Don’t stop any medicine on your own; your doctor will tell you if anything needs to be paused.

Be cautious of unreliable tests. Some “allergy” or “food intolerance” panels offered in the market, such as IgG food tests or machine-based tests, are not reliable for diagnosing allergy and can lead to unnecessary food restrictions. Get tested under the guidance of a qualified doctor.

Step 3: Can It Be Treated?

Yes, allergy can be well controlled once the trigger is known:

• Trigger avoidance: targeted changes at home and work, such as dust-mite-proof bedding, mould control and keeping pets out of the bedroom
• The right medicines: non-drowsy antihistamines, steroid nasal sprays, eye drops, and inhalers if the lungs are involved
• Allergen immunotherapy (allergy vaccine shots): for selected patients with confirmed triggers, gradually increasing doses of the allergen are given over a period of time to reduce the body’s sensitivity, giving long-term relief and reducing the need for medicines

Allergy is a long-term tendency, but with correct diagnosis and treatment most people live comfortably without frequent flare-ups.
