Normal IgE levels vary, typically from 3 to 423 IU/mL for adults. They are measured using a blood test, which assesses total IgE in the serum. This test is crucial for diagnosing allergic diseases and understanding the immune system's response to allergens. The normal range can differ slightly depending on the laboratory's reference intervals.
