Abstract
As of 2007, the 8 Dutch University Medical Centers (UMCs) have agreed to collaborate in, and exchange knowledge regarding, setting up local biobanks, where materials for a wide variety of diseases were collected under the same protocol. These nation-wide protocols are, to a large extent, still in place for most materials collected in the extant 7 UMC biobanks. Materials collected comprise blood derivates, DNA, urine, and tissue samples.
All materials and data are handled in accordance with GDPR (AVG) and Biobank regulations. Researchers may request human body material and/or clinical data.
At LUMC, the protocols to collect and store biomaterials according to national standards have been refined over the years, for example, through automation improvements in sample processing. Registration and storage of all materials is carried out in the Biobank information management system, Sample Navigator. All materials intended for scientific research are assigned a unique code that cannot be traced to the donor without access to Sample Navigator. Access is strictly governed by the LUMC IT department under supervision of the LUMC Biobank Facility.
All pre‑analytical deviations are systematically documented at the sample level to ensure transparency, reproducibility, and high‑quality downstream data use. Deviations are recorded using predefined categories, each accompanied by structured metadata and optional free‑text clarification. This enables traceability, supports FAIR data principles, and allows researchers to assess potential impact on biomarker analyses or clinical interpretation.
This protocol outlines the procedure for processing urine samples at the LUMC, implemented since 2023 and adapted from the national Dutch standard protocol. Primary modifications are the omission of centrifugation and the homogenization of samples.
Materials
  • Urine collection tube (Sarstedt)
  • Various adjustable calibrated pipettes
  • Corning pipette tips with filter, sterile, 100-1000 µl
  • Capped mixing tube
  • Micronics/2D barcode tubes
Safety warnings
No hazardous substances are used.
Ethics statement
Sample collection under this protocol may only be performed with prior approval from the user’s Institutional Ethics Board (or equivalent ethics committee) and only when patients have provided informed consent for the specific biobank.
Procedure
10 ml urine is collected in a commercially available urine collection tube.
The urine collection tube is processed within 4 hours after collection.

Before initiating sample processing (and within 4 hours after collection), the urine collection tube is inspected for pre‑analytical deviations. The following deviation categories are captured for the tube, each accompanied by a free‑text field for additional notes:
  • Incorrect storage temperature prior to processing
  • Deviated storage duration prior to processing
The urine is then transferred to a mixing tube with cap by pipetting.
After homogenization of the collected urine by thoroughly mixing, 3 aliquots of urine (400 µl each) are distributed in Micronics/2D barcode tubes.
The barcode tubes with urine are then stored overnight at -20°C (or until 5 pm on Fridays), after which the tubes are stored in a UHT freezer at -80°C.

After completion of the storage procedure, additional pre‑analytical deviations related to the processing phase are recorded. The following deviation categories are captured for the sample, each with a free‑text field for additional notes:
  • Deviation during centrifugation
  • Storage incident
