A blood test is a quick and simple way to get answers to your underlying allergy questions. Also called a specific IgE (sIgE) blood test, this powerful tool can aid in accurately diagnosing your allergies by measuring the level of specific antibodies in the blood. These antibodies are an indicator of allergic sensitization and can help your healthcare provider determine if you are allergic and to what.
This powerful diagnostic tool can reveal potential sensitization to hundreds of possible allergens with one blood sample. Blood testing has fewer limitations on who can receive it or when it can be performed compared to other types of testing.
You can get an sIgE blood test by making an appointment to visit your healthcare provider, or by taking advantage of convenient options at your local MinuteClinic®, booking an appointment at a lab, or online via telehealth.

Specific IgE Summary:
Specific IgE blood testing for allergies isn’t new, but it’s not as well-known as other options, such as skin-prick testing, and your healthcare provider may not be familiar with it. It’s perfectly OK to research your options and tell your healthcare provider that you want a specific IgE blood test. It can also be helpful to share what you’ve learned with your provider.
