Serum IgE testing

Serum IgE testing measures the level of Immunoglobulin E (IgE) antibodies in your blood, which are involved in allergic reactions. Elevated IgE levels can indicate allergies to certain foods, substances, or environmental factors. During the test, a small blood sample is taken and analyzed in a lab. Results help doctors identify specific allergies and guide treatment options. It's a useful tool for diagnosing allergic conditions and understanding the immune response related to allergies, providing valuable information without the need for direct exposure to potential allergens.
