Learn more
Immunoglobulins or antibodies, play an important role in the immune system and help fight against harmful bacteria and viruses in the body. There are five classes of antibodies and several subclasses. In those that have an allergy, their immune system overreacts to a harmless allergen (such as food, grass or animal dander) by producing IgE. This reaction usually causes irritation to the nose, lungs, throat and skin. The allergen-specific IgE antibody test is used to check for an allergy to a specific allergen. It measures the amount of IgE antibody in the blood targeted for a suspected allergen.
How to prepare for your test
Test limitations
Please be aware that allergy blood tests can sometimes produce false positive results, meaning that a positive result does not always indicate an actual allergy to the substance. Maintaining an allergy diary can be a valuable tool in identifying the most likely triggers of your symptoms. Whenever you experience a reaction, make a note of your exposures over the previous 1–2 hours (e.g., foods, toiletries, pets, plants, etc.). We encourage you to include these details in the supporting information section of your test request to enable our doctors to provide the most accurate and informed interpretation of your results.
