What is it? Why is it important?
- Sample processing (e.g. BM handling prior to long or short-term storage)
- Sample storage, where BM is kept until analysis (e.g. storage at -80°C)
The aim is to document the reception of BM, which includes:
- Reception time = duration of sample transport (e.g. time-laps between the collection and reception of BM)
- A quality check documenting:
- BM received (e.g. type, volume or amount)
- Packaging (e.g. condition of transport container, temperature, broken collection tubes / spillage)
- Labelling (e.g. correct coding, matching and identification of BM, collection tube(s) and paper document(s))
- Non-conformities (e.g. BM is damaged, missing, or additional material is included)
- Measures taken in the event of quality concerns upon arrival of BM (maintain or destroy)
- The registration of BM-related information in BIMS (e.g. includes all information collected from collection until reception)
What do I need to do?
Define sample reception processes. Aspects to consider include:
- Quality checks: Create a list of standardised questions to be answered upon BM reception:
- Define sample acceptance criteria (e.g. minimal volume, maximum acceptable delay between collection and reception).
- If criteria are not met define how to proceed (e.g. BM destruction, adaptations to processing procedures, report non-conformity)
- Follow-up procedures: Upon reception, BM is either forwarded for additional processing, or directly stored in a storage unit. Include relevant information regarding laboratory or storage conditions (e.g. on ice, current freezer temperature during storage time)
- Documentation in BIMS: Include all required information needed for:
- The tracking of BM (e.g. BM identifier for subsequent retrieval, ongoing surveillance of BM inventory)
- BM quality evaluation during downstream analysis
