Doetinchem Cohort Study – National Institute for Public Health and the Environment

The Doetinchem Cohort Study is a population based cohort, focussed on lifestyle and chronic diseases. About 6,000 individuals aged 20-59 years entered the study during 1987-1991, and are re-examined every five years. For each round of investigation biological samples (plasma, serum, buffy coats) have been stored.

Biobank access procedure:

Major terms for access: Contact the principal investigator.
Ethical and legal compliance: Approved by medical ethics committee
Speed and reliability of delivery: Depending on the nature of the collaboration, we ask a lumpsum contribution to maintenance of the data collection up to 5 kE, and (if needed) the costs for datamanagement/retrieval.’

Quality management system:

Storage: A total of 25 ml of non-fasting venous blood is collected in every round using three types of vacutainers: NaF, serum and EDTA. Samples are centrifuged and aliquoted in 25 cryovial tubes, including plasma, serum, erythrocytes and buffy coat. Standard storage is at -80˚ C. Blood samples are available for all participants for all rounds, though there are some differences per measurement round refer-ring to storage conditions (in round 1 only -20˚ C, and additional -196˚ C storage in round 2 only) or number of tubes. From round 5 onwards we took spot urine samples and stored those at -80˚ C, after testing the sample for urinary tract infection.
