PrecisionLink Biobank for Health Discovery at Boston Children’s

The PrecisionLink Biobank for Health Discovery at Boston Children’s Hospital gives patients and families an opportunity to participate in research at Boston Children’s and helps us build a valuable collection of samples and data that can advance knowledge of health and disease and improve the medical care we provide. The Biobank is an initiative of the Computational Health Informatics Program (CHIP).

How does the Biobank work?

The Biobank helps researchers understand how biological processes in blood, tissue, and cells can help diagnose, treat, and possibly prevent certain diseases and conditions. Participants voluntarily donate samples leftover from their medical care along with health information, which allows researchers to study a variety of diseases, conditions, and disorders.

Why join the Biobank at Boston Children’s Hospital?

The Biobank allows patients and their families to contribute directly to groundbreaking research. For example, Biobank contributors have already helped us discover the following:

  • New factors that contribute to severe asthma
  • Which environmental exposures may be contributing to rising autism prevalence
  • Biomarkers that can help diagnose and evaluate patients with inflammatory bowel disease
  • New biomarkers for traumatic brain injury outcomes
  • How Trisomy 21 affects patients’ stature, growth, and bone development
  • How immune cells help us fight infection
  • How people grow and early ways to diagnose excessive weight gain in children

Who can contribute to the Biobank?

All Boston Children’s patients and their families can contribute to the Biobank. Participation is completely voluntary, and participants can withdraw at any time. There are no additional costs to you or your insurance company for participation.

What happens if I decide to join the Biobank?

You’ll be asked to take 5 minutes to review and sign a document saying you would like to be a participant.

We’ll ask your permission to:

  • Collect and store samples that are no longer needed for your clinical care
  • Allow researchers to study these samples along with information in your/your child’s medical record
  • Optional: a voluntarily one-time sample of blood which can be added to the next clinical blood draw at Boston Children’s

What happens to my samples and information?

All samples and health information are securely stored at Boston Children’s Hospital’s main campus. Samples are physically stored at in an access-restricted lab and all personal health information is stored in secured databases, behind our firewall. Samples and health information are only accessed by Boston Children’s researchers who’ve obtained approval from the Biobank Scientific Review Committee. These approved researchers use samples for a broad range of studies, including:
