Allergy Testing - Conjunctival Challenge Test

DESCRIPTION

Conjunctival challenge tests also known as provocation tests in allergic individuals are proposed as a method to confirm the diagnosis of allergy, study the signs and symptoms of the allergic reaction, sample the cells and mediators of the allergic reaction and evaluate anti-inflammatory therapy.  The test is performed by applying a single drop of allergen solution directly into the conjunctival sac of the eye followed by observation for redness, itchiness, tearing and other similar symptoms.  These tests are often used in research protocols that require an objective standard for evaluating clinical sensitivity to an allergen.
