ALLERGY PROFILE ELISA

An Allergy Profile (ELISA) is a blood test that measures specific IgE antibodies against common allergens using the ELISA (Enzyme-Linked Immunosorbent Assay) method.

It helps identify what substances may be triggering allergic symptoms.

🔬 How ELISA Allergy Testing Works

1️⃣ A plate is coated with specific allergens (e.g., dust mite, pollen, foods).
2️⃣ Your blood sample is added.
3️⃣ If IgE antibodies are present, they bind to the allergen.
4️⃣ An enzyme reaction produces a color change → measured by a machine.

Stronger color = higher IgE level.
