Biobanks are collections of human biological materials (biospecimens) that are linked to relevant de-identified personal and health information and held specifically for use in health and medical research. Their object is to provide a resource for researchers to use to advance our understanding of human health and disease.

Biobanks are increasingly important to research in the areas of understanding the risk factors that underlie complex diseases, and translating biomedical research into improvements in healthcare.

This biobank will provide information for future research as advances in technology become available.

For example, research into PTSD and the mechanisms by which it can affect the body is a developing area. Advances in the understanding of mechanisms, chemical mediators that may be involved and the specific genes and epigenetic changes (changes to genes as a result of environmental influences) are occurring. By having biosamples available to us from the participants in the GMRF-PTSD study we (and other collaborators) will be able to investigate these new areas as they become known.


The comprehensiveness of the medical and psychological evaluations performed for the PTSD Initiative study makes development of a functional PTSD Biobank worthwhile. The ultimate objective of the development of the PTSD Initiative Biobank is to have a centralised database containing searchable participant data and sample information, allowing ease of access to samples and data for future research.
