What is a Biobank?

Image.png


Biobanks are specialized repositories that collect and store biological samples and information from various sources (animals, plants, microorganisms, humans, etc.). The focus of this module is on human biobanks, which collect and store biological samples from human donors (e.g., saliva, urine, blood) and health-related data (e.g., health records, family history, lifestyle, genetic, occupational, residential information, etc.) for research purposes and the development of new diagnostic procedures,  preventive measures, and treatments. Some biobanks collect health-related data from donors throughout their life, and researchers may continue to access and make use of this data after donors’ demise.


These repositories play a crucial role in advancing biomedical research, by providing scientists with access to a diverse array of high-quality biological materials and continuously updated health-related data. Biobanks ensure the preservation of sample integrity,  allowing for researchers to conduct longitudinal studies and other investigations into various health conditions at multiple scales.


For instance, by analyzing samples and data, researchers can search for biological markers, investigate the relationship between biological markers and the sensitivity of diseases to treatment, the aggressiveness of diseases, progression, risk of death, as well as study the genetic and environmental factors that influence the development of certain diseases.


Legal instruments and guidance govern biobank operations to protect the autonomy and dignity of donors, along with their fundamental rights (e.g., private life and data protection) while also advancing the societal benefit of conducting research to address the key public health challenges.


Overall, biobanks contribute significantly to the progress of medical science and personalized medicine.

Donating Samples To A Biobank

Donating Samples.png


Alison, a 42-year-old woman in robust health, was invited to contribute to scientific advancement by donating biological material along with health-related information (data) to a biobank. Alison explained to her friends and family that she wanted to contribute to medical research ‘to give something back’ after seeing her father’s successful treatment for cancer.


The biobank provided Alison with detailed information about the purpose of the biobank,  the types of samples and data needed, risks and potential benefits related to the donation to biobanking and the right to withdraw consent.


Alison then gave her consent to the donation process, acknowledging her understanding and agreement to participate.


Before donating the samples, Alison underwent a thorough screening process which included a review of her medical history and a physical examination.


The samples were carefully labelled, processed, and stored in secure, controlled environments. Storage conditions also comply with stringent ethical and privacy protocols, ensuring the preservation of Alison’s privacy and confidentiality.


Alison was told that her personal information would be de-identified or pseudonymized to protect her identity. As part of the consent process, Alison also gave permission for the biobank to contact her in the future to follow up on her health as she ages and potentially invite her to participate in further studies beyond the scope of her original donation. Maintaining contact with donors is crucial for biobanks when samples are used for longitudinal studies or when follow-up health information is needed.


Alison's donation is now part of a valuable resource for researchers studying various health conditions,  including genetic predispositions and disease markers. Her contribution will allow scientists to conduct longitudinal studies, advancing the understanding of health and potential breakthroughs in personalized medicine. Alison's decision exemplifies the vital role individuals can play in shaping the future of medical research through biobank donations.
