What is IgE?
A total IgE test may be ordered when you have periodic or persistent symptoms that may be due to an allergic reaction. Symptoms may include those that suggest skin, respiratory, and/or digestive involvement, like itching, itchy eyes, eczema, nausea, vomiting, sneezing, coughing, difficulty breathing, or Asthma symptoms: wheezing, breathlessness, coughing, tightness in the chest. It is also ordered when a doctor suspects a parasitic infection.
Why is IgE done?
- If you have symptoms suggesting an allergic disorder like periodic or persistent itching, nausea, vomiting, diarrhea, eczema, itchy eyes, sneezing, coughing etc.
- If your doctor is suspecting a parasitic infection
Interpreting IgE results
- If your total IgE level is increased, it usually indicates that you are suffering from one or more allergies. Sometimes, increased levels are also associated with parasitic infections.
- An elevated IgE indicates an allergic process but does not indicate what a person is allergic to. In general, the greater the number of things a person is allergic to, the higher is the IgE level.
