What does it mean when immunoglobulin IgE levels are high?

Elevated immunoglobulin IgE levels may be caused by the following factors: 1. Allergic diseases: such as allergic asthma, allergic rhinitis. When allergens enter the body, they stimulate B cells to produce increased amounts of IgE. 2. Parasitic infections: when the body is infected with parasites, the immune system produces large amounts of IgE to fight the infection. 3. Immune system disorders: such as systemic lupus erythematosus, rheumatoid arthritis, which may also lead to elevated IgE levels. 4. Other diseases: IgE-producing multiple myeloma and other hematologic disorders, as well as idiopathic nephrotic syndrome, can also cause increased IgE levels. Elevated IgE levels are usually associated with various factors including allergies, infections, and immune system disorders. Diagnosis and treatment should be based on specific symptoms and test results.
