Allergy / Immunology
Also known as: IgE Allergy Test, Quantitative IgE Test, Immunoglobulin E Test
If you experience severe allergy symptoms like difficulty breathing, swelling of the face or throat, or sudden widespread hives, seek immediate medical attention. These could be signs of anaphylactic shock.
This test checks the total amount of IgE antibodies in your blood. IgE antibodies are special proteins. Your body's defense system makes them. They help protect you from things like allergens that your body thinks are bad.
Your doctor orders this test to see if you have allergies. This is especially true if you have allergy symptoms. It is also used if you cannot have skin allergy tests. This test can also help find certain infections. It can also find problems with your immune system. It helps your doctor choose the best treatment for asthma caused by allergies.
Reference ranges for total IgE can vary significantly between different laboratories and depend on factors like age. Always compare your results to the specific range provided by the lab that performed your test.
