Allergic Reaction (cont.)

Allergic Reaction Diagnosis

For typical allergic reactions, your health-care provider will examine you and ask questions about your symptoms and their timing. Blood tests and X-rays are not needed except under unusual circumstances.

In case of severe reactions, you will be evaluated quickly in the emergency department in order to make a diagnosis. The first step for the health-care provider is to judge the severity of the allergic reaction.

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