Allergies are a common and chronic condition that involves the body’s immune system. Normally, the immune system works to fight off viruses, bacteria and other infectious agents. When there is an allergic reaction, the immune system considers the normally existing substance causing allergy as a harmful substance . To fight this perceived threat, the immune system makes antibodies called immunoglobulin E (IgE). Besides dust and pollen, other common allergens may include animal dander, foods, including nuts and shellfish, and certain medicines, such as penicillin.
Interpretation: If the total IgE levels are higher than normal, it is likely that there is some kind of allergy but it does not reveal to which substance the body is allergic to. A specific IgE test will help identify the particular allergy. Low levels mean that you are not allergic to those particular items.
