Allergy, Elm
Elm allergy blood test measures the total amount of allergen specific immunoglobulin E (IgE) in an individual’s blood. IgE is a type of antibody which is produced by the body’s immune system. A substance that triggers an allergic immune response is known as an allergen.
Elm trees begin to bloom in February and continue to release pollen until late March. If someone is allergic to Elm pollen, they may experience asthma-like symptoms after inhaling this wind pollen.
Thus, getting an Elm allergy test is recommended to diagnose an allergy to Elm pollen.

What foods should be avoided if you have an Elm allergy?
