Question

Quizplus · Accepted Answer

Immunoglobulin E (IgE) is an antibody produced by the immune system in response to an allergen. In cases of allergy, the level of IgE increases in response to the allergen. Therefore, if the level of IgE is elevated in a patient suspected of having a cat allergy, it would confirm the suspicion. Cortisol, aldosterone, and blood glucose levels are not specifically associated with allergic reactions.
