Pathology Tests Explained

Pathology Tests Explained (PTEx) is a not-for-profit organisation managed by a Board composed of representatives from professional bodies in pathology. PTEx provides a website information service for the public about pathology tests.

Vision and mission

PTEx's aim is to provide the public with information about pathology testing that you can rely on as being accurate and authoritative. Importantly, they take steps to maintain their independence. Their funding comes from a range of professional organisations and government sources, and they do not accept or post any advertising. In this way they are able to provide evidence-based information that is free from commercial interest.

How Pathology Tests Explained can help

If your health carer has asked you to go and have some blood tests you can find information about those tests on www.pathologytestsexplained.org,au. You will find information about why your doctor has requested the tests, what you may need to do as part of collecting the blood or other sample, and what the results of the tests will mean. All information is written by professionals working in Australian pathology laboratories.
