Diagnosis of Allergies

Allergy symptoms often resemble a cold, however the cold seems to linger. Symptoms include a runny nose, itchy eyes, headaches, and sinus pain. Usually there is no fever. It is important to see a doctor about any respiratory symptoms that last longer than a week or two. Properly trained physicians can recognize patterns of potential allergens. Often skin tests or blood tests are used to determine specific antibody levels reacting to a certain allergen. If there are unusually high levels of an antibody known as IgE, it is a good indication of an allergic reaction.
