Pathology is made up of several specialty areas. The following sections include information on the range of testing and services offered by ACT Pathology within each of the specialty areas:
The Department of Anatomical Pathology provides diagnostic, consultative, research and teaching services to The Canberra Hospital, Calvary Hospital, National Capital Private Hospital and medical practitioners of the Canberra region and Southern Area Health Service.
The department is staffed by 8 Specialist Anatomical Pathologists with 6 registrars, 19 scientists , 2 mortuary staff and 5 secretaries.
The Canberra Hospital is a teaching institution hence the department is involved in teaching medical students, laboratory staff, Anatomical Pathology trainees and trainees in other specialties.

The projects can involve pure ultrastructure examination and/or the use of immunolocalisation techniques.
Chemical Pathology provides a wide range of routine and specialised assays, as well as consultative, research and teaching services.
Most of the routine investigations are performed on a 24 hour basis with some specialised Endocrinology and Protein Chemistry testing offered seven days a week.
Routine testing such as renal and liver function tests, cardiac marker testing, lipid profiles, therapeutic drugs and blood gases (including co-oximetry) are available on a 24 hour basis.
Testing for Immuno-Suppressive Drugs

We also offer glycated haemoglobins 5 days a week (normal working hours).
For investigation of phaeochromocytoma we offer urinary adrenaline/noradrenaline and for detection of Carcinoid tumour we measure 5H1AA.
Some of our manual testing includes analysis of renal calculi, detection of reducing substances in urine and faeces and performance of LS ratios in amniotic fluid.
We have recently installed atomic absorption equipment and currently offer Aluminium analysis in body fluids. Over the coming months we will be widening the range of trace and heavy metals being performed (lead, selenium, cadmium, arsenic).
Australasian Association of Clinical Biochemists (AACB)
Cytogenetics is the study of genetic material at the cellular level.
Specimens are accepted from hospital inpatients and outpatients as well as from outside sources.
The cytogenetics unit provides a high quality service in all areas of clinical cytogenetics, including testing for:
- Haematological malignancies.
- Solid tumours
- Constitutional abnormalities including paediatric dysmorphic features, developmental delay, failure to thrive.
- Multiple miscarriage or infertility.
- Primary/secondary amenorrhoea.
- Prenatal testing of amniotic and chorionic villus samples.
- Products of conception.

ACT Pathology provides a 24 hour Haematology and Transfusion service, offering a wide range of routine and specialised testing procedures.
The laboratory employs eight specialist haematologists with broad experience in both clinical and diagnostic fields, three registrars and a number of highly experienced scientific and technical staff with up-to-date specialised knowledge in the disciplines of Haematology and Blood Transfusion Medicine.
Some of the extensive services that we offer include:
- All routine Haematological, Coagulation and Transfusion procedures.
- Advice and clinical consultation in transfusion medicine and the appropriate use of blood and blood products.
- Clinical Haematology consultations with advice on the interpretation of abnormal or unexpected results and other services including the collection and reporting of bone marrow aspiration and trephine biopsies.
- Autologous haemopoietic stem cell transplantation.
- Immunophenotyping by flow cytometry- for the diagnosis of leukaemia, lymphoproliferative disorders and immunodeficiencies. This technology is also used for a number of specialised tests and in the estimation of stem cell populations in patients undergoing stem cell transplantation.
- Investigation of thalassaemia and other haemoglobinopathies.
- Specialised assessment of haemostatic function including coagulation factor assays for the diagnosis of the haemophilias, von Willebrands disease and acquired bleeding disorders. A comprehensive range of testing for prethrombotic disorders including; lupus anticoagulant, anti-thrombin III, protein C and S , and Activated Protein C resistance (APC).
- The molecular laboratory offers PCR testing for a range of conditions including leukaemia, lymphoma, Factor Va Leiden and prothrombin gene mutations.
