How is Angioedema Diagnosed?

Angioedema is diagnosed based on clinical evaluation, medical history, and, if necessary, laboratory tests. The doctor may ask about recent exposure to potential allergens, new medications, and family history of angioedema. For hereditary angioedema, specific blood tests to measure C1 inhibitor levels and function can confirm the diagnosis. In cases of idiopathic angioedema, other underlying conditions may be ruled out through various tests.
