Allergen-specific IgE Antibody Test

Allergen-specific IgE Antibody Test, also known as Allergy Blood Test, measures the level of Immunoglobulin E (IgE) antibody in the blood, in an attempt to screen for allergies to particular allergens.

The results will be positive or negative.

  • A normal result is negative. It suggests that the person is very likely to have no allergy to the allergen. But that can be wrong in some cases.
  • An abnormal result is high/positive. This indicates that the person has an allergy to the allergen. However, the result is not diagnostic of the severity of the condition.

Note: Allergy Blood Test results must be interpreted with great care, lest false negatives/positives occur.
