Question

Quizplus · Accepted Answer

The most commonly used test for confirming hay fever is the measurement of Immunoglobulin E (IgE) levels in the blood. Elevated levels of IgE indicate an allergic response to specific allergens, such as pollen or dust mites, which are typically responsible for hay fever symptoms. IFE, IgA, and immunosuppressant cyclosporine are not relevant tests for diagnosing hay fever.
