Western Diagnostic Pathology

At Western Diagnostic Pathology, we're committed to supporting practitioners by delivering timely, accurate, and high quality diagnostic results. We know that patients all across Western Australia and the Northern Territory rely on us to collect, analyse, and report results – and it's a responsibility we take very seriously. We have a team of more than 900 people who work year round to deliver results. Our team includes collectors, couriers, laboratory assistants, scientists, and pathologists, all supported by operations, logistics, administration, data entry, and call centre teams. While our core laboratory is located in Myaree, we have 10 laboratories across WA– many based in hospitals – and two in the NT to ensure we can get results back to doctors as soon as possible. We also have more than 200 collection centres for patients to visit at their convenience. In addition to this, we provide a number of Workplace Health & Safety testing for commercial clients. Western Diagnostic Pathology (WDP) was founded in 1972 by Dr D.J. McCully and four other pathologist partners from the Sir Charles Gardner Hospital. "Western Pathology" as it was then known, expanded rapidly and quickly became recognised as the pre-eminent Western Australian pathology provider. In 1986, Markalinga, the developer and owner of Perth and Sydney's premier tertiary private hospitals of the time, purchased the shares in the operating company of the pathology service, with Dr McCully and the other senior pathologists continuing to retain ownership of the pathology partnership. Since that date, the practice has experienced a number of different controlling shareholders and eventually was acquired in 2008 by Healius Ltd and became part of the Specialist Diagnostic Services network of pathology practices.
