Blood Allergy Test Fluorescence Assay Blood is used to detect the presence of immunoglobulin E (IgE) antibodies against a specific allergen in the blood. This test helps to know the immune response of the body towards the specific allergen.
What are Antibodies and their types?
Antibodies are the protective proteins produced by the immune system and also known as immunoglobulins. Antibodies are produced when any foreign substance or virus or bacteria enters into the body. These foreign substances are known as antigens. Antibodies recognize and attach to the antigens in order to remove them from the body. There are five (5) subtypes of antibodies and they are IgG, IgM, IgA, IgD, IgE.
When someone is exposed to the specific allergen, the body detects it as a foreign substance and releases the specific IgE antibody. IgE binds to the basophils and mast cells and then recognize the allergen and cause an allergic reaction. IgE binds to the basophils and mast cells.
Why this test is performed?
This test is performed when you are suspected to have an allergy. Your doctor may ask to perform this test if you experience signs and symptoms such as red skin, runny or itchy nose, sneezing, itchy or watery eyes, sore throat, coughing or wheezing, hives, difficulty breathing, nausea, vomiting, stomach pain, diarrhea, etc. This test may also be performed to evaluate and to check the effectiveness of the treatment.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your Blood Allergy Test Fluorescence Assay. Your doctor will give specific instructions depending on your condition on how to prepare for Blood Allergy Test Fluorescence Assay.
No specific preparation is required for this test. However, follow all the instructions given by the healthcare provider.
The normal reference range may vary depending on gender, age, health history, etc.
If your test results show high levels of IgE antibodies than the given normal reference range, it may indicate that the person is most likely to have an allergy.
If your test results are lower than the normal reference range, it may indicate that the person is unlikely to have an allergy.
Based on the test results, your doctor may advise appropriate medical treatments, lifestyle modifications, or further diagnostic tests.
