Why Allergy Testing is Important for Conjunctivitis
Although there isn't a single blood test to diagnose allergic conjunctivitis itself, allergy testing is essential for determining the specific environmental triggers causing your symptoms. This information is crucial for developing effective avoidance strategies and targeted treatment plans to prevent future episodes.
Understanding Your Results
Positive results on allergy testing indicate sensitization to specific allergens that may be triggering your conjunctivitis symptoms. This information helps healthcare providers recommend appropriate antihistamines, eye drops, or other treatments, as well as environmental control measures to reduce exposure to identified triggers.
