How to prevent allergic reactions?
The best way to prevent allergic reactions is to avoid exposure to the allergen. However, this may not always be possible. In such cases, medications and immunotherapy can help.
What is the role of IgE in allergies?
IgE is a type of antibody that is produced by the immune system when it overreacts to an allergen. It triggers the release of certain chemicals that cause the symptoms of an allergic reaction.

The tests are important tools in diagnosing allergies. They can provide valuable information about what substances you may be allergic to, so that you and your doctor can develop a treatment plan to help manage your symptoms. However, these tests are not definitive. You can have high levels of IgE antibodies to a substance but never experience symptoms when exposed to that substance. Therefore, these tests should be used in conjunction with other diagnostic tools and clinical symptoms for an accurate diagnosis. Always consult your doctor if you are experiencing symptoms of an allergic reaction.
