how is hereditary angioedema diagnosed?

 

Getting a diagnosis starts by talking with your doctor. Because hereditary angioedema (HAE) is rare, few people have heard of it, including many doctors. In fact, many doctors will never see a patient with HAE. That's why getting an accurate diagnosis can be challenging.

If your doctor thinks you might have HAE, he or she will likely ask about your symptoms and when you first noticed them. Because HAE is usually passed down through relatives, your doctor will probably also ask if anyone in your family has swelling episodes or has been diagnosed with HAE.

Tests to confirm an HAE diagnosis

If your doctor thinks you might have HAE, a blood test is often used to confirm the diagnosis. This measures how much C1-INH protein you have. They will also look at other information, like your symptoms, how they respond to certain medications, and your family history.
