Recently, I have had some allergies and went to the hospital for a blood test, which showed high levels of immunoglobulin E (IgE). May I ask what elevated immunoglobulin E levels indicate?

Dr. Yang Ziqi
Elevated immunoglobulin E (IgE) levels generally indicate that a patient may be facing various health conditions. 1. It may suggest the presence of allergic reactions in the patient, such as allergic rhinitis or extrinsic asthma, conditions that can lead to a significant increase in IgE levels. 2. Liver diseases, such as autoimmune liver disease, may also lead to elevated IgE levels, which may be related to the patient's living environment, dietary habits, viral infections, and other factors. 3. Parasitic infections can also stimulate the immune system, causing an increase in IgE levels. It is important to note that elevated IgE does not necessarily mean the patient has an allergic disease; it may also be associated with infectious diseases or immune system disorders such as systemic lupus erythematosus and rheumatoid arthritis. Therefore, when elevated IgE levels are detected, patients should seek medical attention promptly and undergo further examinations to identify the underlying cause, enabling targeted treatment.
