What else do I need to know?

  • Patients attending the Respiratory Laboratory should bring their reading glasses if worn, any dentures and hearing aids.
  • The Laboratory is located some distance from Main Reception so patients with mobility or breathing problems are advised to arrive in good time for their appointment so that they can get an electric buggy from Main Reception.
