Conditions and Shipment

Please label the sample tube(s) with a minimum of two (2), and ideally three (3), unique identifiers (e.g. name, date of birth, and either address or Medical Record Number) on each tube. In the interest of patient safety, we are unable to accept improperly or inadequately labelled samples.

For some indications, to further minimise the risk of mis-identification, duplicate blood samples should be collected, at an interval of greater than 20 minutes apart. Where duplicate samples are collected, every effort should be made to ensure the two samples are collected and processed independently of each other.

Ship all patient samples at room temperature. Do not freeze any sample! Do not place any sample directly on ice or in direct contact with ice!

Blood samples should ordinarily arrive in our lab within 3 days after collection. All other samples must be provided on the same day, or by overnight courier.

Contact the laboratory if you are uncertain as to the amount of DNA required.


Important: for MBS tests the Medicare Assignment information must be completed on the SEALS referral form. For non-MBS rebateable tests an invoice will be sent either to the institution, or the individual nominated by the referrer. Some tests may not proceed until a patient has provided a signed financial consent for payment.

Other general laboratory information

Please contact the laboratory for additional information such as Turn-around Times, non-standard consent forms, and lists of factors that can interfere with test results.

Dr Buckley's research interest is principally in disease gene identification in paediatric congenital anomalies; with major publications concerning the identification of the SP110 gene as the cause of a form of severe combined immunodeficiency, the SCL29A3 gene in pigmented hypertrichosis with insulin dependent diabetes mellitus, and the FREM1 gene in metopic craniosynostosis.  Between 2008 and 2011 he was the recipient of a Marie Curie International Incoming Fellowship for a project directed at the implementation of massively parallel sequencing for disease gene identification in diagnostics and in research, a project which is ongoing with the development of a Centre for Medical Genomics within the SEALS Genetic Laboratory. Current research funding includes support for Centre of Research Excellence for neuromuscular disease and an NHMRC project grant for neuromuscular diseases (PI Prof Kathryn North).

Dr Buckley is actively involved in specialist training having held positions as Registrar of the RCPA Board of Censors, RCPA Chief Examiner in Genetics, HGSA Chief Examiner in Molecular Genetics, and is currently a member of the RCPA/RACP JSAC in Clinical Genetics/Genetic Pathology.

Professor Leslie Burnett MB BS, MSc (Bioinf), PhD, DBA, FHGSA (Molecular Genetics), FRCPA, MAACB, FACB, FCAP

Senior Staff Specialist
Conjoint Professor, School of Medical Sciences, UNSW
Honorary Professor in Pathology and Genetic Medicine, University of Sydney

Dr Leslie Burnett is a Clinical Pathologist, specialising in Genetic Pathology, Chemical Pathology and Bioinformatics. He holds qualifications in Medicine, Science and Information Technology, and Fellowships in Genetics from the Royal College of Pathologists of Australasia and the Human Genetics Society of Australasia, as well as Fellowship of the College of American Pathologists. Professor Burnett holds honorary appointments with a number of universities. He is also a consultant genetic pathologist of the Kinghorn Centre for Clinical Genomics at the Garvan Institute of Medical Research.

Leslie pioneered the development and introduction of a number of pathology and genetics initiatives, which today have become mainstream pathology and healthcare programs. These include introducing Community Genetics into Australia, and developing the Australasian pre- and post-analytical Quality Assurance programs. He has served in senior national and international professional roles in pathology, including as Ministerial appointee, Chairman, or President of several peak National and International organisations. His contributions have been recognised with both national and international Awards.

His current interests are in the areas of genetic biochemistry, screening for genetic conditions in at-risk communities, genomic bioinformatics, and bioinformatic modelling of population genetics and cell biology processes.


Dr Scott Mead MBChB, BHB, PhD, FRCPA

Staff Specialist Genetic Pathologist
Conjoint Senior Lecturer, St Vincent’s Clinical School, UNSW
Dr Scott Mead is a medical graduate of the University of Auckland (New Zealand), where he also gained a PhD in Molecular Medicine. He obtained fellowship of the RCPA in 2011, following genetic pathology training undertaken at the University of Otago (Christchurch, NZ) and Royal Prince Alfred Hospital (Sydney).
Dr Mead is currently a Conjoint Senior Lecturer at the School of Medical Sciences, UNSW and is a member of the RCPA Genetics Advisory Committee. He is actively involved in genetic pathology registrar placement at SEALS Genetics and in conjunction with his role as a consultant genetic pathologist at Douglass Hanly Moir Pathology (Sonic Genetics) and at the Kinghorn Centre for Clinical Genomics at the Garvan Institute of Medical Research.
Scott has a long-standing interest in cancer genetics and has been involved in cancer research initiatives in Australia and overseas. This has included identifying translocation breakpoints in neuroblastoma patients (Institute of Child Health, Great Ormond Street Hospital, UK), modelling acute myeloid leukaemia in zebrafish (University of Auckland, NZ) and most recently characterising mutations in pancreatic cancer as part of the Australian Pancreatic Cancer Initiative (APGI) and International Cancer Genome Consortium (ICGC). This work (Garvan Institute of Medical Research, Sydney) has led to a clinical trial (IMPACT) looking at stratifying pancreatic cancer patients to different treatment options based on the mutation profile of their tumour. This reflects Dr Mead’s primary interest in genetic diagnostics, which is the clinical application of massively parallel sequencing (NGS) technologies.
