Qualification of a cord blood bank (CBB) is a complex process that includes evaluation of multiple aspects of donor screening and testing, processing, accreditation and approval by professional cell therapy groups, and results of received cord blood units. The University of Minnesota Medical Center Cell Therapy Laboratory has established a CBB vendor qualification process to ensure the CBB meets established regulatory and quality requirements.
The deployed qualification of CBBs is based on retrospective and prospective review of the CBB.
Forty-one CBBs were evaluated retrospectively: seven CBBs were disqualified based on failed quality control (QC) results. Eight CBBs did not meet the criteria for retrospective qualification because fewer than 3 cord blood units were received and the CBB was not accredited. As of March 2012, three US and one non-US CBBs have been qualified prospectively. One CBB withdrew from the qualification process after successful completion of the comprehensive survey and subsequent failure of the provided QC unit to pass the minimum criteria. One CBB failed the prospective qualification process based on processing methods that were revealed during the paper portion of the evaluation.
A CBB qualification process is necessary for a transplant center to manage the qualification of the large number of CBBs needed to support a umbilical cord blood transplantation program. A transplant center that has utilized cord blood for a number of years before implementation of a qualification process should use a retrospective qualification process along with a prospective process.
脐带血库(CBB)的资质是一个复杂的过程,包括对供体筛选和检测、处理、专业细胞治疗团体的认证和批准以及所接收脐带血单位的多个方面进行评估。明尼苏达大学医学中心细胞治疗实验室已经建立了 CBB 供应商资格认证流程,以确保 CBB 符合既定的监管和质量要求。
部署的 CBB 资格认证是基于对 CBB 的回顾性和前瞻性审查。
对 41 个 CBB 进行了回顾性评估:7 个 CBB 因质量控制(QC)结果不合格而被取消资格。由于接收的脐带血单位少于 3 个,且 CBB 未获得认证,因此 8 个 CBB 不符合回顾性资格认证标准。截至 2012 年 3 月,有 3 个美国和 1 个非美国的 CBB 已通过前瞻性资格认证。一个 CBB 在完成全面调查后撤回了资格认证流程,随后提供的 QC 单位未能通过最低标准。一个 CBB 因在评估的文件部分揭示的处理方法而未能通过前瞻性资格认证过程。
对于移植中心来说,管理大量支持脐带血移植计划所需的 CBB 的资格认证是必要的。在实施资格认证流程之前已经使用脐带血多年的移植中心应该同时使用回顾性资格认证流程和前瞻性流程。
