Diagnosis of anaphylaxis is based on the specific symptoms a patient experiences. 帮助确诊, healthcare providers might ask patients questions regarding their previous allergic reactions. 此外, patients may be given a blood test to measure the amount of a certain enzyme (tryptase) that can be elevated up to three hours after an anaphylaxis episode.
