At Pulmovista Clinics, patients can book directly — a GP referral is not required. Many of my patients self-refer after researching their symptoms, or are referred by a family member who has previously been treated at Pulmovista. That said, if you do have a GP referral letter summarising your history and previous investigations, please bring it — it helps me start the consultation with important background information and avoids repeating investigations you have already had.
