Is it possible to include only storage of HBM in the scope of my ISO20387 accreditation?

Acquisition, storage and distribution are all obligatory activities in the BELAC ISO20387 accreditation scope. Therefore it’s not possible to receive an ISO20387 accreditation if your biobank only includes storage in its accreditation scope, and excludes acquisition and distribution.
However, the activities of collection, preparation, testing and preservation are not obligatory activities in the BELAC ISO20387 accreditation scope. Your biobank can still apply for ISO20387 accrediation when it excludes one or more of these activities from their accreditation scope.
