Allergy - Biomarker Test

This test is also called as the Allergy Biomarker Fluorescence Assay Blood. It helps to determine the level of IgE antibodies in the blood. This is usually performed to confirm Biomarker Allergy. It is also done during and after the treatment of Biomarker Allergy to understand if the therapy is effective and the person has outgrown the allergy. This is usually done to help diagnose an allergy a person may have, to some specific substance, called allergens, based on the symptoms seen. The idea is to find out what the allergy trigger is, whether it is some food substance, environmental, or genetic.

No special preparation is required for undergoing this test. Typically the doctor may issue specific instructions while advising the test, and if so, the same needs to be followed. It is important to inform the doctor about any specific underlying medical conditions or medications that are being taken, including that of allergies at the time. Otherwise, the test can be taken by walking into any clinic or lab at any time without any preparation.

The test reference range of Allergy Biomarker Fluorescence Assay Blood test is not gender or age specific and is uniform across. Increased IgE (>100kU/l) is seen in the results if the person is actually allergic to any specific substance. A point to be noted is that there is a small chance that the person may be allergic even if the test is negative. Elevated lgE levels just indicate that the person is allergic to a specific substance and not necessarily the severity or the cause etc. Further tests including specific allergy tests and clinical correlation of the patient’s history is used to arrive at treatment options.

The Allergy Biomarker Fluorescence Assay Blood is to be done on a blood sample drawn from the body. The procedure itself is simple and takes just a few minutes. The medical practitioner drawing the blood will clean the area for drawing the blood with an alcohol swab. Then a needle with an attached tube is inserted into a vein in your arm and the required amount of blood is drawn. The sealed and labelled blood sample is then sent to the laboratory for analysis and detection of allergen specific IgE. The prick from where the blood is drawn may be covered with gauze or a plaster.
