First, a healthcare provider will insert a small needle into one of the veins in your arm.
After insertion, a small amount of blood will be collected into a test tube or vial.
There is no preparation for an IgE blood test.
You may have a small bruise for a few days at the site.
Results
Everyone has some IgE in their blood.
High IgE
Atotal IgE testresult that is high means that you could have some kind of allergy.
A highspecific IgE testresult means that you may be allergic to the allergen tested.
But both results don’t show what you’re allergic to or how severe your allergy may be.
Your healthcare provider may recommend more testing.
Normal IgE
Everyone has some IgE in their blood.
Different allergy blood test brands can vary in how they test for IgE.
Your healthcare provider may recommend that you get retested to confirm a diagnosis.
One of the most effective treatment plans for allergies involves avoiding the allergen altogether.
