Diagnosis

Your doctor will ask you questions about previous allergic reactions, including whether you've reacted to:

  • Particular foods
  • Medications
  • Latex
  • Insect stings

To help confirm the diagnosis:

  • You might be given a blood test to measure the amount of a certain enzyme (tryptase) that can be elevated up to three hours after anaphylaxis
  • You might be tested for allergies with skin tests or blood tests to help determine your trigger

Many conditions have signs and symptoms similar to those of anaphylaxis. Your doctor will want to rule out other conditions.
