Best Allergy Test Center in Kolkata: Skin Prick Test, Blood Test & More | Dr. Naren Pandey
By Dr. Naren Pandey | Allergist & Asthma Specialist, Kolkata
Are you suffering from repeated sneezing, skin rashes, breathing difficulty, or constant nasal congestion — but don’t know exactly what is causing it? The answer lies in a simple, accurate allergy test.
At the Allergy Asthma Centre, Dr. Naren Pandey offers comprehensive allergy testing in Kolkata — identifying your exact allergen so that the right treatment can be started. This complete guide explains the different types of allergy tests available, how they work, and why accurate diagnosis is the first step toward permanent allergy relief.
Why Is Allergy Testing Important?
Many allergy patients in Kolkata spend years taking antihistamines without knowing exactly what they are allergic to. This leads to:
- Incomplete symptom control
- Repeated flare-ups
- Unnecessary dietary restrictions
- Delayed immunotherapy — the only permanent treatment
Allergy testing identifies your exact trigger — allowing Dr. Naren Pandey to create a personalised treatment plan targeting the root cause of your allergy.
Types of Allergy Tests Available in Kolkata
At Allergy Asthma Centre, we offer the following allergy tests:
1. Skin Prick Test (SPT) — The Gold Standard
The Skin Prick Test is the most accurate, most affordable, and most widely used allergy test in the world — and it is available at our clinic in Kolkata.
How it works:
- Small drops of allergen extracts are placed on the forearm or back
- A tiny lancet is used to prick the skin through each drop
- After 15–20 minutes, the skin is examined for reactions
- A raised, red wheal at any site confirms allergy to that allergen
What it tests:
- House dust mites
- Cockroach allergens
- Mold and fungal spores
- Tree and grass pollen
- Pet dander (cat, dog, bird)
- Common food allergens (milk, egg, wheat, nuts, seafood)
Advantages:
- Results in just 20 minutes ✅
- Tests multiple allergens simultaneously ✅
- Highly accurate — gold standard worldwide ✅
- Affordable and available in-house ✅
- Minimal discomfort — not a blood draw ✅
Who should get a Skin Prick Test:
- Anyone with allergic rhinitis, asthma, or skin allergy
- Patients with recurrent sneezing, itchy eyes, or nasal congestion
- Anyone considering allergy immunotherapy (mandatory before starting)
2. Blood Allergy Test (Specific IgE Test)
The Blood Allergy Test — also called the Specific IgE test or RAST test — measures allergen-specific antibodies in the blood.
How it works:
- A blood sample is drawn from the arm
- The sample is tested in a laboratory for IgE antibodies to specific allergens
- Higher IgE levels indicate greater sensitivity to that allergen
When is it used:
- When skin testing is not possible — due to severe eczema covering the skin
- Patients taking antihistamines who cannot stop medication
- Infants and young children who cannot cooperate with skin testing
- Patients with dermographism (skin that reacts to any pressure)
Advantages:
- No skin reaction risk ✅
- Can be done while on antihistamines ✅
- Objective laboratory measurement ✅
Limitations:
- More expensive than skin prick test
- Results take 1–3 days
- Slightly less sensitive than skin prick test
3. Patch Test — For Contact Allergy
The Patch Test identifies allergens that cause allergic contact dermatitis — skin reactions from substances that touch the skin.
How it works:
- Small patches containing common contact allergens are applied to the back
- Patches remain in place for 48 hours
- Skin is evaluated at 48 hours and again at 72–96 hours for reactions
What it tests:
- Nickel (jewellery, metal accessories)
- Cosmetics, perfumes, and hair dyes
- Rubber and latex
- Preservatives in skincare products
- Industrial chemicals and detergents
Who needs a Patch Test:
- Patients with skin rashes from jewellery, cosmetics, or clothing
- Healthcare workers with latex allergy
- Anyone with suspected contact dermatitis
4. Food Allergy Test
Food allergy testing helps identify which specific foods are triggering your allergy symptoms.
Methods used:
- Skin Prick Test with food allergen panel — milk, egg, wheat, nuts, seafood, soy
- Specific IgE Blood Test for food allergens
- Oral Food Challenge — gold standard for food allergy confirmation
Common food allergens tested in Kolkata:
- Prawns and shellfish — very common in Bengali diet
- Hilsa (ilish) and other fish
- Milk and dairy products
- Eggs
- Peanuts and tree nuts
- Wheat and gluten
- Soy
- Mustard — widely used in Bengali cooking
5. Spirometry (Lung Function Test) — For Asthma
While not a traditional allergy test, spirometry is an essential diagnostic tool for patients with suspected allergic asthma.
How it works:
- Patient breathes into a spirometer device
- Measures lung capacity and airflow speed
- Confirms airway obstruction characteristic of asthma
- Tests response to bronchodilator medication
Available in-house at Allergy Asthma Centre, Kolkata.
