Blood analysis detecting reactive IgE antibodies to food allergens.
Blood test measuring specific IgE antibodies to an allergen to identify a true food allergy.
The IgE test measures the presence of immunoglobulins E in the blood, produced by the immune system in response to an allergen. This examination allows identifying if the body has developed a specific allergic reaction to a food. Results are quantified in units to evaluate the intensity of sensitization. The IgE test is particularly useful for confirming immediate allergies (rapid reactions after consumption). It should be completed with skin tests or oral challenges to establish a definitive diagnosis.
Identifying true food allergies via detection of specific antibodies.
The IgE test should be prescribed by an allergist or doctor. Do not stop exposure to the allergen before the test to ensure reliable results. Positive results must be confirmed by other clinical tests.
