[[cohort|Lifelines]] has collected a wide variety of biosamples from participants in all of our [[general assessments]] as well as during some of our [[additional assessments]]. The following types of biosamples are stored in our biobank and can be requested for use in your research project:

  * [[blood_samples|Blood (plasma)]] samples were collected from Lifelines participants (ages 8+) as part of the [[1A|baseline]], [[2A|second]], and [[3A|third]] assessments.
  * [[blood_samples|Blood (serum)]] samples were collected from Lifelines participants (ages 8+) as part of the [[1A|baseline]], [[2A|second]], and [[3A|third]] assessments.
  * [[blood_samples|Blood (buffycoat)]] samples were collected from Lifelines participants (ages 8+) as part of the [[1A|baseline]], [[2A|second]], and [[3A|third]] assessments.
  * DNA has been extracted from 100,000+ buffycoat samples (during the [[GWAS]] and [[UGLI]] additional assessments for example).
  * [[urine_samples|Urine]] samples were collected from Lifelines participants (ages 8+) as part of the [[1A|baseline]], [[2A|second]], and [[3A|third]] assessments.
  * [[Faecal samples]] were collected from subcohorts of Lifelines participants as part of the following additional assessments: [[DEEP]], [[DAG2]], and [[DAG3]].
  * [[Hair samples]] were collected from participants (ages 18+) during the [[2A|second]] assessment.
  * [[cryopreserved_whole_blood|Whole blood]] samples were collected from 20,000 adult participants during the [[1A|baseline]] assessment.

Note that Lifelines also has results from various [[blood analyses|blood]] and [[urine analyses|urine]] analyses available for reuse.
