How can a blood test help me know if I have allergies?
Requested by Age2B visitor

If you are atopic, or have a predisposition toward developing allergic reactions, your body may produce an antibody called Immunoglobulin E (IgE) that is specific to what causes your allergic reactions. Immunoglobulin E (IgE) is a protective mechanism that is produced when you are exposed to a substance that your body views as a threat. These tests measure the amount of IgE to that specific substance in your blood. Your specific IgE test results are as personal and unique as your fingerprint, and your healthcare professional can use your results to identify any underlying allergic triggers that may be contributing to your symptoms. It is a simple blood test that is easier and less risky to perform than a Skin-Prick Test (SPT) or Oral Food Challenge (OFC).
