also known as Mesquite IgE Ab in Serum by Radioallergosorbent test (RAST)
The Immunoglobulin E IgE Test is a simple blood test used to help screen for allergic diseases and immune system reactions. IgE is an antibody produced by the immune system in response to allergens such as pollen, pet dander, mold, dust mites, and certain foods. When your body identifies a substance as harmful, it may release IgE antibodies that trigger allergic symptoms. Elevated IgE levels are commonly associated with allergic conditions, including allergic rhinitis, asthma, eczema, and certain food allergies. This test measures total IgE levels in the blood, giving insight into whether your immune system may be overreacting to environmental or other triggers. The IgE test can also be used to monitor the effectiveness of allergy treatments such as immunotherapy. Tracking IgE levels over time may help evaluate whether your body’s immune response is improving or stabilizing. What Is Included In This Test? This test includes: Measurement of total Immunoglobulin E IgE levels in the bloodLaboratory analysis to assess overall allergic responseClear numerical results for clinical interpretation This is a total IgE screening test and does not identify specific allergens. Additional testing may be recommended if specific triggers need to be identified. Why Does This Test Matter? Allergic diseases affect millions of individuals and can significantly impact quality of life. Symptoms such as sneezing, itching, wheezing, skin rashes, and digestive discomfort may be linked to elevated IgE levels. Identifying elevated IgE can help guide further allergy evaluation and treatment decisions. For individuals undergoing allergy shots or other therapies, periodic testing can help assess progress and immune response over time. Early detection of immune overactivity may support better symptom management, lifestyle adjustments, and targeted treatment strategies. Understanding your IgE level provides a clearer picture of your immune health and helps you take proactive steps toward relief and long term wellness. Who Should Consider This Test?
