What is ISO 20658?

ISO 20658 is officially titled:

"Medical laboratories โ€” Requirements for collection, transport, receipt, and handling of samples"

It outlines clear requirements and guidelines for the pre-examination phase of laboratory testing. This includes procedures for:

  1. ๐Ÿงช Sample collection (instructions for patients and clinicians)
  2. ๐Ÿšš Sample transportation (including temperature and timing)
  3. ๐Ÿ“ฅ Receipt and registration at the lab
  4. ๐Ÿ—ƒ๏ธ Handling and storage until testing is performed
  5. โœ… Ensuring patient identification, traceability, and documentation

ISO 20658 can be applied independently or in conjunction with ISO 15189, the core standard for medical laboratory quality and competence.

Why is ISO 20658 important?

Errors in the pre-analytical phase account for up to 70% of all diagnostic mistakes in clinical laboratories. These include:

  1. โŒ Mislabeling or misidentification of patient samples
  2. ๐Ÿšซ Improper transport and storage leading to sample degradation
  3. ๐Ÿงพ Incomplete clinical or patient information
  4. ๐Ÿ“‰ Delay in processing due to administrative inefficiencies

ISO 20658 addresses these challenges by ensuring that labs and collection centers:

  1. โœ… Follow structured, consistent processes
  2. ๐Ÿ“‹ Maintain complete and accurate documentation
  3. ๐Ÿ” Communicate effectively between collection points and testing facilities
  4. ๐Ÿ’ก Train staff to handle specimens safely and correctly
