Allergic Reaction Diagnosis

Patient Comments

For typical allergic reactions, a doctor will examine an individual and ask questions about his or her symptoms and their timing. Blood tests and X-rays are not needed except under unusual circumstances.

In the case of severe reactions, an individual will be evaluated quickly in an emergency department in order to make a diagnosis. The first step for the doctor is to judge the severity of the allergic reaction.

  • Blood pressure and pulse are checked.
  • An examination determines whether the patient needs help breathing.
  • Often, an IV line is placed in case anti-allergy (antihistamine) medications are needed quickly.
  • If the patient can speak, he or she will be asked about allergy triggers and previous reactions.
